How to Identify Real vs Imitation Gemstones in India (Expert Guide for 2025)
Buying gemstones in India has always carried emotion, trust, and expectation. People buy stones for astrology, jewellery, healing, weddings, and gifts. But with the rise of imitation stones, glass-filled varieties, synthetic gems, and aggressive online selling, many buyers feel unsure. They ask questions because they fear getting cheated, they compare prices because the gap feels confusing, and they doubt sellers because information is limited.
If you want to feel confident while buying gemstones in 2025, this guide will help you understand the difference between real vs imitation gemstones in India using expert insights, simple tests, and reliable verification methods used by gemologists.
Why People in India Struggle to Identify Genuine Gemstones
- Confusing price differences
A ruby priced at ₹1,500 online and another priced at ₹35,000 in a showroom creates doubt. Without knowledge, buyers assume the cheaper one is a good deal.
- Online stores selling synthetic stones without clarity
Many marketplaces list stones without mentioning whether they are natural, treated, lab-grown, or imitation.
- Fake gemstones look perfect
Natural stones usually have tiny marks, while fake ones look smooth and flawless. This tricks people who think “perfect means better.”
- Lack of gemstone education in India
Most buyers rely on trust, not facts. This leaves them open to manipulation.
These concerns are valid. That is why understanding authenticity is important before making any purchase.
What Are Real Gemstones?
A real gemstone forms deep within the earth through natural geological processes. This gives each stone:
- Mineral patterns
- Natural inclusions
- Depth
- Density
- Color zoning
- Unique structure
Examples of natural gemstones often bought in India:
- Emerald
- Ruby
- Sapphire
- Pearl
- Amethyst
- Garnet
- Topaz
- Natural Zircon
Real gemstones are rarely perfect, and that is one of the strongest signs of authenticity.
What Are Imitation Gemstones?
Imitation gemstones are artificially created to look like natural stones. They use materials such as:
- Glass
- Resin
- Plastic
- Synthetic crystal
- Composite layers (doublets, triplets)
- Dyed material
They may look attractive but lack the natural characteristics, durability, and value of real gemstones.
Real vs Imitation Gemstones in India: Expert Identification Guide (2025)
This guide uses methods followed by gemologists, jewellers, labs, and gemstone experts. Some tests can be done at home, while others need professional equipment.
1. Natural Inclusions Check (Most Reliable Sign)
Real gemstones have small internal features formed by nature such as:
- Tiny crystals
- Feather-like lines
- Natural growth patterns
- Mineral specks
Fake gemstones:
- Look clear and identical
- Often contain bubbles (typical in glass stones)
Use a flashlight or phone to check. Irregular lines suggest authenticity.
1. Natural Inclusions Check (Most Reliable Sign)
- Inspect the Cut and Finish
Natural gemstones are cut to enhance beauty, not hide flaws.
- The cut might not be perfectly symmetrical.
- Light reflections appear soft and deep.
Fake stones are machine-polished to look perfect but appear flat and overly shiny. Check with a magnifying glass to see how the stone reflects light.
2. Color Variation Test
Real gemstones:
- Show slight variation
- Display depth and tone changes in light
Fake gemstones:
- Look flat and uniform
- Shine only from the surface
This check is very effective for emeralds, rubies, sapphires, and topaz.
3. Weight and Density Test
Real stones feel heavier because minerals have higher density.
Fake stones feel light due to glass or resin.
When two stones are the same size, weight difference becomes clear.
4. Temperature Test
Natural gemstones stay cool for a longer time.
Imitation stones warm quickly when held.
This test helps with sapphire, ruby, emerald, and amethyst identification.
5. Hardness and Scratch Test
Each gemstone has a hardness rating on the Mohs scale.
Examples:
- Sapphire/Ruby: 9
- Emerald: 7.5 to 8
- Amethyst: 7
- Glass: Around 5
Fake gemstones scratch easily.
Do not test this on expensive stones without guidance.
6. Light Reflection and Depth Test
Real gemstones show:
- Strong inner reflection
- Depth when rotated
Fake gemstones show:
- Shallow reflection
- Surface shine only
This is useful for comparing zircon, topaz, and sapphire variations.
7. Heat Test for Dyed Stones
Dyed stones lose color when heated lightly nearby (never touch the stone).
Fake turquoise, dyed quartz, and imitation emerald often fail this test.
Again, attempt only if the gemstone is low-value.
8. Certification – The Final Proof
In India, certified stones carry the highest trust. Certification confirms:
- Whether the stone is natural or synthetic
- If it was treated (heat, oil, glass-filled, resin-filled)
- Color
- Clarity
- Weight
- Origin (if possible)
Trusted Indian labs include:
- GIA India
- IGI
- SGL
- GII
- BIS-approved labs
A certificate removes doubt and protects your purchase.
2025 Update: Fake Gemstone Trends Rising in India
As demand increases, so does fraud. Common imitation trends in 2024–2025:
- Glass-filled rubies being sold as natural
- Synthetic sapphires imported in bulk
- Dyed quartz sold as emerald
- Composite opals sold as natural opal
- Artificial pearls replacing natural pearls
Understanding these trends helps buyers stay careful.
Common Fake Gemstone Issues in Indian Markets
Delhi (Karol Bagh, Chandni Chowk)
Glass-filled rubies and low-grade emeralds are commonly mixed.
Jaipur (Johari Bazaar)
Synthetic stones sometimes enter tourist markets.
Mumbai (Zaveri Bazaar)
Composite stones and dyed stones appear often.
Online marketplaces
Many listings do not mention “synthetic,” “created,” or “treated,” which misleads buyers.
Quick Home Test Checklist (Buyer-Friendly)
Before buying, use this simple list:
- Does the stone show natural lines?
- Does it feel heavier?
- Does the color look deep, not flat?
- Does it stay cool?
- Does the seller provide a certificate?
- Does the price seem too low for a natural gemstone?
- Is the seller clear about treatment details?
If any answer feels wrong, step back.
Natural vs Fake Gemstone Price Comparison in India
Approximate price range differences:
Gemstone | Real Stone (Approx.) | Fake/I imitation (Approx.) |
Emerald | ₹5,000 – ₹2,00,000+ | ₹200 – ₹2,000 |
Ruby | ₹10,000 – ₹3,00,000+ | ₹100 – ₹1,500 |
Sapphire | ₹8,000 – ₹4,00,000+ | ₹300 – ₹2,500 |
Pearl | ₹2,000 – ₹80,000+ | ₹50 – ₹500 |
This gap is one of the strongest clues during purchase.
Why Certified Luxury Jewellery Is Safer in 2025
Indian buyers choose certified gemstone jewellery because:
- They do not want imitation stones sold as natural
- Certification protects long-term value
- Astrology stones require natural origins
- Reliable brands explain treatments clearly

A certified gemstone is easier to trust, easier to resell, and holds emotional value.
