Questions to Ask Before Buying a Gemstone Online

Buying a gemstone online can be convenient, but it can also make it harder to judge the stone in person.

Unlike shopping at a physical store, you may not be able to hold the gemstone, view it under different lighting, or examine it with a loupe before placing your order.

That is why asking the right questions before buying a gemstone online is important.

Whether you're looking for an Emerald (Panna), Ruby (Manik), Blue Sapphire (Neelam), Yellow Sapphire (Pukhraj), Pearl (Moti), Cat's Eye (Lehsunia), Amethyst, Aquamarine, Turquoise, Tourmaline, or another gemstone, understanding the product specifications can help you make a more informed decision.

Before purchasing, it is worth asking about:

• Gemstone identity
• Natural or synthetic status
• Treatments
• Carat weight
• Ratti weight, if applicable
• Dimensions
• Color and clarity
• Certification
• Origin
• Return policy
• Product photographs and videos
• Jewelry metal and setting
• Care requirements

At MithilaShri, we believe customers should have access to clear gemstone information before making an online purchase.

Why Should You Ask Questions Before Buying a Gemstone Online?

A gemstone photograph does not tell you everything about the stone.

Images and videos can show:

• Color
• Shape
• Cut
• Setting
• General appearance

But they may not fully establish:

• Natural or synthetic status
• Treatment history
• Exact weight
• Internal characteristics
• Laboratory identification
• Origin

Asking questions before purchasing helps you understand what you are actually buying.

1. What Type of Gemstone Is It?

Start with the most basic question:

What exactly is the gemstone being offered?

For example, if a listing says "Panna," confirm that the stone is actually being identified as Emerald.

Likewise:

• Manik = Ruby
• Neelam = Blue Sapphire
• Pukhraj = Yellow Sapphire
• Moti = Pearl
• Lehsunia = Cat's Eye

Traditional names can sometimes be used broadly in the marketplace, so checking the exact gemstone identity is important.

2. Is the Gemstone Natural, Synthetic, or an Imitation?

This is one of the most important questions to ask.

A gemstone may be:

Natural

Formed through natural geological or biological processes.

Synthetic

Laboratory-grown material with essentially the same chemical composition and crystal structure as its natural counterpart.

Imitation

A different material used to resemble another gemstone.

For example, glass can be manufactured to resemble certain gemstones.

These categories are not interchangeable and can have very different values.

Always ask the seller to clearly state which category applies.

3. Has the Gemstone Been Treated?

Ask:

Has this gemstone undergone any treatment or enhancement?

Gemstone treatments can include:

• Heat treatment
• Oiling
• Resin filling
• Fracture filling
• Dyeing
• Diffusion
• Coating
• Irradiation
• Other enhancement methods

Treatment is not automatically a negative characteristic.

Many gemstone treatments are widely used in the industry.

The important point is disclosure.

You should know whether the gemstone has been treated and, where relevant, what type of treatment was used.

4. What Is the Exact Carat Weight?

Ask for the gemstone's actual carat weight.

For example:

Weight: 2.08 ct

Carat is the internationally recognized unit used to measure gemstone weight.

Remember:

1 carat = 0.2 grams

Do not assume that a gemstone described as "large" or "premium size" has a particular weight.

Check the actual specification.

5. Is the Weight Given in Carat or Ratti?

This question is particularly important in India.

Some gemstone listings use:

Carat (ct)

while others use:

Ratti

Ratti is a traditional Indian weight measurement commonly used in gemstone and astrological markets.

A commonly used modern market conversion is approximately:

1 Ratti ≈ 0.91 Carat

However, traditional standards can vary.

If a seller gives you the weight in ratti, ask:

What is the equivalent carat weight?

This makes it easier to compare gemstones from different sellers.

6. What Are the Exact Gemstone Dimensions?

Ask for the gemstone's dimensions in millimeters.

For example:

9.3 × 6.6 × 4.7 mm

These measurements generally represent:

Length × Width × Depth

Dimensions are particularly important when buying a gemstone that will be placed into an existing ring or jewelry setting.

Remember:

Carat = Weight

Millimeters = Physical Dimensions

7. What Is the Gemstone's Shape and Cut?

Ask whether the gemstone is:

• Round
• Oval
• Cushion
• Pear
• Marquise
• Emerald cut
• Princess
• Cabochon
• Freeform
• Another shape

Also ask whether it is faceted or cabochon-cut.

The cut affects:

• Appearance
• Light behavior
• Face-up size
• Proportions
• Setting requirements

Two gemstones with the same carat weight can look very different because of their shape and cut.

8. What Is the Color Like in Natural Lighting?

Color is one of the most important visual characteristics of a colored gemstone.

Ask whether the photographs and videos were taken under:

• Daylight
• Studio lighting
• LED lighting
• Other artificial lighting

Gemstone color can look different under different light sources.

This is especially important when buying colorful stones such as:

• Emerald
• Ruby
• Sapphire
• Amethyst
• Aquamarine
• Tourmaline

If possible, look for photographs or videos taken under neutral lighting.

9. Are the Photos and Videos of the Actual Gemstone?

This is a very useful question.

Ask:

Are the photographs and videos showing the exact gemstone I will receive?

A stock photograph may represent a product category rather than the individual stone being sold.

For a loose gemstone or unique high-value stone, actual product photographs and videos can provide more useful information.

10. Can I See the Gemstone From Multiple Angles?

A single front-facing photograph may not show:

• Depth
• Pavilion
• Back surface
• Side profile
• Inclusions
• Surface-reaching fractures

Ask whether the seller can provide photographs or videos from multiple angles.

Useful views include:

• Front
• Side
• Back
• Angled view
• Rotating video

11. Can I See the Inclusions?

If the gemstone is natural, ask about its internal characteristics.

You can ask:

Are there visible inclusions?

Can you provide a magnified photograph or video?

Inclusions are not automatically negative.

They may provide useful information about:

• Internal structure
• Formation
• Possible identity
• Natural characteristics

However, some inclusions or fractures may affect transparency or durability.

12. Is the Gemstone Transparent, Translucent, or Opaque?

Ask about the gemstone's transparency.

It may be described as:

• Transparent
• Translucent
• Opaque

Transparency describes how readily light passes through the gemstone.

This is different from clarity.

A gemstone can contain inclusions and still be transparent.

Understanding both characteristics helps you evaluate the gemstone more accurately.

13. What Is the Gemstone's Clarity Like?

Ask about the gemstone's clarity and visible inclusions.

For example:

• Eye-clean
• Slightly included
• Moderately included
• Heavily included

Keep in mind that clarity standards differ between gemstone varieties.

A natural Emerald, for example, commonly contains inclusions, so it should not necessarily be judged by the same expectations as a Diamond.

14. Is the Gemstone Lab Certified?

For valuable gemstones, ask:

Is a laboratory report available?

A suitable gemological report may provide information such as:

• Gemstone identification
• Weight
• Measurements
• Natural or synthetic status
• Treatment information
• Other relevant observations

A certificate can provide additional information, but buyers should still understand what the specific report does and does not establish.

15. Which Laboratory Issued the Report?

If a certificate is provided, check:

• Laboratory name
• Report number
• Date
• Gemstone identification
• Weight
• Measurements
• Treatment information

It is also useful to determine whether the report is for the exact gemstone being purchased.

Do not assume that every document labeled "certificate" provides the same level of gemological information.

16. Does the Certificate Match the Gemstone?

This is an important step.

Check whether the certificate details match the product listing.

For example:

Certificate Weight: 2.08 ct

Product Weight: 2.08 ct

Also compare:

• Measurements
• Shape
• Gemstone identity
• Report number
• Photographs, if included

If the details do not match, ask the seller for clarification before purchasing.

17. What Is the Origin of the Gemstone?

For some gemstones, origin can be an important value factor.

You can ask:

What is the claimed geographic origin of the gemstone?

However, origin determination can require specialized laboratory analysis and may not always be possible.

If origin is important to you, ask whether the laboratory report specifically provides an origin opinion.

Do not assume that a seller's stated origin is automatically laboratory-confirmed.

18. Is the Origin Laboratory-Confirmed?

This is different from simply asking where the seller says the gemstone came from.

For example:

"Kashmir Sapphire"

and:

"Sapphire with a laboratory origin opinion identifying Kashmir origin"

are not necessarily equivalent claims.

If origin matters to the purchase, ask for appropriate documentation.

19. What Is the Return or Exchange Policy?

Always check the return policy before buying an expensive gemstone online.

Ask:

• How many days do I have to return it?
• Is the return free?
• Is there a restocking fee?
• Is the gemstone required to be unworn?
• Does the certificate need to be returned?
• Are custom-made rings returnable?
• How long does the refund take?

A clear return policy can make online purchasing more comfortable.

20. What Happens If the Gemstone Is Damaged During Shipping?

Ask about shipping protection.

Find out:

• Whether the package is insured
• How damage claims are handled
• Whether signature delivery is used for high-value orders
• What you should do if the package arrives damaged

Keep the packaging until you have inspected the gemstone and confirmed that everything is correct.

21. Is the Gemstone Suitable for My Jewelry Setting?

If you already have a ring or pendant setting, ask whether the gemstone's dimensions will fit.

Provide the jeweler with:

• Setting dimensions
• Stone length
• Stone width
• Stone depth
• Shape

This can prevent problems later.

A gemstone that looks suitable in a photograph may not physically fit your existing setting.

22. What Metal Is Used in the Jewelry?

If you are buying a mounted gemstone, ask about the metal.

Common options include:

• Sterling Silver
• Gold
• Panchdhatu
• Gold-plated metals
• Other jewelry alloys

Also ask about:

• Metal purity
• Plating
• Hallmarks, where applicable
• Care requirements

The gemstone is only one part of a finished jewelry piece.

23. Is the Gemstone Natural or Treated According to the Certificate?

If a laboratory report is available, compare the seller's description with the report.

For example, if the listing says:

Natural and untreated

the report should support that claim where the report covers those characteristics.

This is particularly important for expensive gemstones.

24. What Care Does the Gemstone Require?

Different gemstones have different levels of durability and sensitivity.

Ask:

How should this gemstone be cleaned and stored?

Depending on the gemstone, you may need to avoid:

• Harsh chemicals
• Ultrasonic cleaners
• Sudden temperature changes
• Strong impact
• Prolonged exposure to certain conditions

The appropriate care method depends on the gemstone and any treatments it has received.

25. Is the Gemstone Suitable for Everyday Wear?

Not every gemstone is equally suitable for everyday jewelry.

Consider:

• Hardness
• Toughness
• Cleavage
• Fractures
• Treatment
• Setting style

A gemstone intended for a daily-wear ring may require different considerations from one intended for occasional wear in a pendant.

Ask the seller or jeweler about suitable use and care.

26. Is This Gemstone Suitable for Astrological Use?

If you are buying a gemstone for traditional astrological purposes, ask the seller for factual information about the stone rather than relying only on broad claims about results.

You may want to confirm:

• Gemstone identity
• Weight
• Natural or synthetic status
• Treatment
• Certification
• Dimensions

For the appropriate gemstone and weight according to a specific astrological tradition, consult a qualified astrologer.

Traditional astrological recommendations are based on cultural and astrological beliefs and should not be treated as scientifically proven methods for producing specific outcomes.

27. What Ratti-to-Carat Conversion Are You Using?

If the gemstone is recommended in ratti, ask the seller which standard they are using.

A commonly used approximate conversion is:

1 Ratti ≈ 0.91 Carat

But different traditional standards can exist.

Therefore, instead of simply asking:

"Is this 5 ratti?"

also ask:

"What is the actual carat weight?"

This gives you a more precise basis for comparison.

28. Are There Any Disclosures About Treatments or Enhancements?

Treatment disclosure is particularly important because treatments can affect:

• Appearance
• Durability
• Care
• Value
• Market expectations

Ask for a clear answer rather than relying on terms such as:

• "Premium"
• "Original"
• "Natural-looking"
• "High quality"

These marketing terms do not replace specific treatment information.

29. What Makes This Gemstone Different From Cheaper Options?

If you are comparing multiple gemstones, ask the seller what differentiates the products.

For example:

Why is this Emerald priced higher than another Emerald of the same carat weight?

Possible differences could include:

• Color
• Clarity
• Transparency
• Cut
• Origin
• Treatment
• Rarity
• Certification

This question can help you understand what you are paying for.

30. Is the Price Based Only on Carat Weight?

A gemstone's price is rarely determined by weight alone.

Two gemstones with the same carat weight can have very different prices.

Pricing may depend on:

• Color
• Clarity
• Transparency
• Cut
• Treatment
• Origin
• Rarity
• Demand
• Overall quality

Therefore, avoid assuming that:

More Carats = Automatically Better Value

Red Flags to Watch for When Buying Gemstones Online

While shopping online, be cautious if a seller:

Avoids Giving Exact Specifications

If there is no clear information about weight or dimensions, ask for it.

Uses Only Marketing Claims

Terms like "100% original," "powerful," "super premium," or "guaranteed results" do not replace gemological information.

Refuses to Disclose Treatment

Treatment disclosure is important when evaluating gemstones.

Uses Only Stock Photos

Ask whether the photograph shows the actual stone.

Provides an Unclear Certificate

Check what the report actually identifies and whether it matches the gemstone.

Makes Guaranteed Astrological Claims

Astrological benefits are matters of traditional belief and should not be presented as scientifically guaranteed outcomes.

How to Compare Two Gemstones Online

Suppose you are comparing two Emeralds.

Don't look only at price and carat weight.

Create a comparison like this:

This makes it easier to understand why two seemingly similar gemstones may have different prices.

Why Gemstone Certification Matters

A laboratory report can provide independent information about a gemstone's characteristics.

Depending on the laboratory and report type, it may identify:

• Gemstone species or variety
• Natural or synthetic status
• Weight
• Measurements
• Treatment information
• Sometimes origin

However, not every certificate covers every characteristic.

Always read the actual report rather than relying only on the word "certified."

Why Product Videos Are Useful

Videos can provide a better impression of a gemstone than a single photograph.

A useful gemstone video may show:

• Rotation
• Color from different angles
• Facet reflections
• Surface condition
• Overall appearance

However, video still cannot replace professional laboratory examination when definitive identification or treatment determination is required.

Why Lighting Matters When Buying Online

Gemstones can look different under different lighting conditions.

A photograph taken under strong studio lights may not look identical to the gemstone under:

• Daylight
• Indoor lighting
• Warm lighting
• Cool lighting

This is particularly important for colored gemstones where color is a major consideration.

If possible, review multiple photographs and videos under different lighting conditions.

Why Screen Settings Can Change Gemstone Appearance

Your phone or computer display can affect how a gemstone appears.

Differences in:

• Screen brightness
• Color temperature
• Display calibration
• HDR settings

can change the perceived color.

Therefore, online photographs should be treated as a useful visual reference, not a perfect representation of the gemstone's color in every environment.

Buying a Loose Gemstone vs Buying a Gemstone Ring

The questions can be slightly different.

Loose Gemstone

Pay particular attention to:

• Carat
• Dimensions
• Shape
• Cut
• Clarity
• Transparency
• Treatment
• Certification

Gemstone Ring

Also consider:

• Ring size
• Metal
• Setting
• Prong security
• Ring dimensions
• Wearability
• Return policy

A mounted gemstone can also be harder to inspect because part of the stone is hidden by the setting.

Frequently Asked Questions

What should I ask before buying a gemstone online?

Ask about gemstone identity, natural or synthetic status, treatment, carat weight, dimensions, color, clarity, transparency, certification, origin, return policy, and care requirements.

How do I know if an online gemstone is natural?

Ask whether it is natural, synthetic, or an imitation and look for appropriate gemological documentation. Appearance alone cannot reliably establish natural origin.

Should I ask whether a gemstone is treated?

Yes. Treatment disclosure is an important part of understanding a gemstone's characteristics, care requirements, and market value.

What is more important, carat or dimensions?

They describe different things. Carat measures weight, while dimensions describe physical size. Both can be useful when evaluating a gemstone.

Should I buy a gemstone based only on ratti?

No. If ratti is provided, ask for the actual carat weight as well because ratti standards can vary.

Are gemstone certificates important?

For valuable gemstones, an appropriate laboratory report can provide useful independent information. However, you should check exactly what the report covers.

Do all gemstone certificates prove that a gemstone is natural?

No. Different reports provide different information. Read the report details carefully.

Can a treated gemstone still be natural?

Yes. A gemstone can be natural in origin while also having undergone a treatment. Natural status and treatment status are separate characteristics.

Should online gemstone photographs be trusted completely?

Photographs and videos are useful, but lighting, camera settings, editing, and screen differences can affect appearance. They should not be treated as a substitute for professional examination.

What should I check if I am buying an astrological gemstone?

Check the gemstone identity, weight, dimensions, natural status, treatment, and certification. For the appropriate gemstone and weight according to a particular astrological tradition, consult a qualified astrologer.

Final Thoughts

Buying a gemstone online does not have to be complicated.

The key is to ask the right questions before placing your order.

Before purchasing, confirm:

Gemstone Identity + Natural Status + Treatment + Carat Weight + Dimensions + Color + Clarity + Transparency + Certification + Return Policy

Don't rely only on photographs, product names, or marketing descriptions.

A gemstone that looks similar to another may differ significantly in quality, treatment, origin, transparency, clarity, or value.

And remember that natural does not automatically mean untreated, while treated does not automatically mean fake. These are separate characteristics that should be clearly disclosed.

Whether you're buying an Emerald, Ruby, Blue Sapphire, Yellow Sapphire, Pearl, Cat's Eye, Amethyst, Aquamarine, Turquoise, Tourmaline, or another gemstone, taking a few minutes to verify the specifications can help you make a more informed purchase.

At MithilaShri, we encourage customers to review the gemstone's identity, weight, dimensions, treatment information, authenticity, certification, and overall specifications before making a purchase.
