A beautiful stone is easy to love, but how do you know it is the real thing? With so many options in the market, it helps to understand what you are actually buying. This guide covers the basics so you can shop with confidence.
First, Know the Difference-
-
Natural: formed in the earth and cut and polished by people. Often called genuine or real.
-
Synthetic (lab-grown): made in a lab with the same chemical makeup as the natural stone. These are real gemstones, but not natural.
-
Imitation: a different material, usually glass or plastic, made to look like a gemstone.
-
Treated: a natural stone enhanced with heat, dye or fillers. This is common and acceptable if it is disclosed.
Pure does not always mean untreated. What matters is that the seller tells you exactly what the stone is.
Simple Checks You Can Do at Home-
These checks give you clues, but none of them is proof. Treat them as a first filter only.
-
Look for inclusions: Natural stones usually have tiny internal marks, called inclusions. A perfectly clear, flawless stone at a low price deserves a second look.
-
Use a 10x loupe: A small jeweller's loupe helps you see inclusions, bubbles or surface marks. Round bubbles often point to glass.
-
Feel the temperature: Real stones usually feel cool to the touch and stay cool longer than glass or plastic.
-
Check the weight: Real gemstones tend to feel heavier than plastic or glass of the same size.
-
Check the colour: Natural colour often has slight variation. Colour that is perfectly even or unusually bright can signal dye or a synthetic.
-
Inspect the edges: Worn, chipped or scratched facets can tell you about the stone's hardness. Glass scratches and wears more easily.
Please avoid scratch tests, acid tests or heating a stone at home. They can damage a valuable piece and can still give misleading results.
The Only Reliable Proof: Certification
Many treatments and synthetics cannot be spotted by the eye, even by experts. A report from a recognised gemmology laboratory is the most dependable proof. A good certificate lists the stone's identity, whether it is natural or synthetic, its weight, dimensions, colour and any known treatments.
Ask for a certificate from a reputed lab, and check that the details on the report match the stone you are buying.
Questions to Ask Before You Buy
-
Is this stone natural, synthetic or treated?
-
Does it come with a lab certificate?
-
What is the carat weight and the stone's origin, if known?
-
What is the return and exchange policy?
-
Is the metal setting hallmarked or quality-tested?
Red Flags to Watch For
-
Prices that are far below the market rate.
-
Sellers who avoid questions about treatment or origin.
-
No certificate or invoice, or vague product descriptions.
-
Claims such as 'guaranteed' or 'one hundred percent pure' with no proof.
