5 Signs of a Fake Sapphire — Buyer Protection Guide (Sri Lanka)
Blue Sapphire is Sri Lanka’s pride — the Ceylon Sapphire is loved worldwide for its rich color and value.
But because sapphires are expensive, fake stones are common in the market.
Whether you’re buying online or in a shop, you must know how to identify a fake sapphire before paying.
Here are 5 clear signs to protect yourself when buying gemstones in Sri Lanka 👇
✅ 1️⃣ The Color Looks Too Perfect
Real sapphires have:
✔ Natural color zoning
✔ Gradual tone variations
✔ Slight imperfections
Fake sapphires made from glass or synthetic materials may look:
❌ Too bright
❌ Too uniform
❌ Artificially clean
👉 Always check color in daylight, not just inside a shop.
✅ 2️⃣ The Stone Feels Light and Warm
Real sapphires are heavier and stay cool when held.
Try a quick test:
- Hold the stone in your hand for 10–20 seconds
✅ Real = still cool
❌ Fake = warms up fast
✅ 3️⃣ No Inclusions = Red Flag 🚩
Every natural sapphire has small inclusions, like:
- Feathers
- Crystals
- Needles
If a sapphire has zero inclusions, it is likely:
❌ Synthetic
❌ Lab-created
❌ High-quality glass
💡 Use a magnifying glass or ask a certified seller to check internally.
✅ 4️⃣ Fake Stones Scratch Easily
Sapphires are very hard — 9 on the Mohs scale 🪨
Nearly as hard as diamonds.
Glass and fake stones:
❌ Scratch easily
❌ Lose polish over time
Do not perform scratch tests yourself — it may damage the stone — ask a professional.
✅ 5️⃣ Suspiciously Low Price
A genuine sapphire cannot be extremely cheap.
If someone offers:
💙 “Royal Blue Sapphire – Very Cheap!” 😳
Then it is:
⚠ Fake
or
⚠ Extremely low grade
👉 If the price looks too good to be true, it is.
✅ Ask for Certification — Every Time
Before buying, request a certificate from trusted labs:
- NGJA 🇱🇰
- GLC 🇱🇰
- GIA / IGI (international)
A certificate confirms:
✅ Authenticity
✅ Heat treatment
✅ Carat weight & clarity
✅ Country of origin
No certificate = No trust ❌

The safest way is to use a transparent marketplace where sellers are reachable directly.
