Introduction
Gemstones have been valued for centuries for their beauty, rarity, cultural significance, and traditional connection with astrology. From Ruby and Emerald to Yellow Sapphire, Blue Sapphire, Pearl, and Red Coral, gemstones are commonly used in jewellery and are also popular in Vedic astrology.
However, with the growing demand for gemstones, customers may come across natural, treated, synthetic, and imitation stones. Knowing the difference is important before making a purchase.
In this guide, we will explore practical ways to identify gemstones and what to check before buying one.
What Is a Genuine Gemstone?
A genuine gemstone generally refers to a naturally occurring gemstone that comes from the earth. However, natural gemstones can also be treated to improve their colour, clarity, or appearance.
This means that “natural” and “untreated” are not necessarily the same thing.
A gemstone can be:
- Natural – formed naturally in the earth.
- Treated – natural but enhanced through an accepted treatment.
- Synthetic – laboratory-grown material with essentially the same chemical composition and crystal structure as its natural counterpart.
- Imitation – a different material made to look like a gemstone.
Understanding these categories can help customers make better purchasing decisions.
1. Check the Gemstone Certificate
One of the most reliable steps is to ask for a gemstone identification report from a reputable gemological laboratory.
Depending on the laboratory and stone, a report may provide information about:
- Gemstone variety
- Natural or synthetic origin
- Treatments detected
- Weight and measurements
- Colour and characteristics
A certificate should be verified with the issuing laboratory whenever possible.
2. Examine the Colour
Natural gemstones often display subtle variations in colour and tone. Extremely uniform colour does not automatically mean a gemstone is fake, but unusual perfection can be a reason to ask more questions.
For example, a seller claiming that a large gemstone has exceptional colour and clarity at an unusually low price should be approached carefully.
Remember: Colour alone cannot prove whether a gemstone is genuine.
3. Look at Internal Inclusions
Many natural gemstones contain internal characteristics known as inclusions. These can sometimes provide useful clues about their origin.
However, inclusions should not be used as a simple “real vs fake” test. Some natural stones can be very clean, while synthetic stones can contain manufactured inclusions designed to imitate natural ones.
A trained gemologist can examine these characteristics using professional equipment.
4. Be Careful With Home Tests
You may find online advice recommending tests such as:
- Scratch tests
- Glass-scratching tests
- Heating tests
- Breath tests
- Water tests
- Newspaper tests
These methods are often unreliable and can potentially damage the gemstone.
For valuable gemstones, avoid experimenting with household tests. Professional examination is a much safer option.
5. Check the Price
Price can provide an important warning sign.
If a seller offers a gemstone described as rare, natural, high-quality, and untreated at an unusually low price, investigate before buying.
However, price alone cannot establish authenticity. Different gemstones vary greatly in value based on colour, clarity, size, origin, treatments, and market demand.
6. Ask About Treatments
Gemstone treatments are common in the jewellery industry. Some treatments are accepted and can improve a stone’s appearance or durability.
Examples can include:
- Heating
- Filling
- Irradiation
- Dyeing
- Coating
A trustworthy seller should clearly disclose known treatments rather than presenting a treated gemstone as untreated.
7. Buy From a Transparent Seller
The seller you choose matters.
Before purchasing, check whether the business provides:
- Detailed product information
- Clear gemstone specifications
- Authenticity documentation
- Treatment disclosure
- Return or exchange policies
- Customer reviews
- Contact and business information
Avoid sellers who make extraordinary claims but cannot provide basic information about the gemstone.
8. Get Valuable Gemstones Professionally Tested
For expensive gemstones, professional testing is the safest approach.
A qualified gemologist or reputable gemological laboratory can use specialized instruments to examine properties such as refractive index, specific gravity, spectroscopy, and microscopic characteristics.
This is especially important when buying high-value gemstones for jewellery or traditional astrological use.
Natural vs Synthetic vs Imitation Gemstones
| Type | Description |
|---|---|
| Natural | Formed naturally in the earth |
| Treated Natural | Natural gemstone that has been enhanced through treatment |
| Synthetic | Laboratory-grown material with essentially the same material characteristics as its natural counterpart |
| Imitation | Different material designed to look like another gemstone |
Understanding these differences helps you know exactly what you are paying for.
Common Red Flags When Buying Gemstones
Be cautious if a seller:
- Guarantees that a gemstone will solve financial or health problems.
- Refuses to provide basic product information.
- Claims every stone is completely untreated without documentation.
- Offers a supposedly rare gemstone at an unbelievably low price.
- Provides a certificate that cannot be verified.
- Pressures you to make an immediate purchase.
- Avoids answering questions about treatments or origin.
Why Authenticity Matters for Astrology Products
For people purchasing gemstones for traditional astrological purposes, authenticity and correct identification are particularly important.
The traditional astrological association of a gemstone is based on its specific identity. Therefore, customers should know exactly what gemstone they are purchasing rather than relying only on appearance or marketing claims.
If a gemstone is being recommended according to a birth chart, consulting a knowledgeable astrologer can also help with selection.
Final Thoughts
Identifying a genuine gemstone is not always possible with the naked eye. Colour, appearance, inclusions, and price can provide clues, but they cannot replace professional gemological testing.
Before purchasing an expensive gemstone, look for transparent product information and obtain a report from a reputable gemological laboratory when appropriate.
At AstroGems, the goal should be to educate customers, provide transparent product information, and help them make confident purchasing decisions based on quality and authenticity—not unrealistic promises.
Choose authenticity. Choose quality. Choose your gemstone with confidence.
