How a gem is priced
Coloured gems are priced per carat, by comparing them with similar stones. These decide where a stone sits:
- 1Colour. The most important. A vivid, even colour is worth many times a pale or dark one.
- 2Weight. Fine stones get dearer PER CARAT as they get bigger — a 5 ct sapphire is rarer than five 1 ct sapphires.
- 3Treatment. Most sapphires and rubies are heated. A natural, unheated stone usually sells for 30–50% more — but only with a lab report that says so.
- 4Clarity and cut. Eye clean and well cut stones shine. Inclusions you can see, or a lumpy native cut, lower the price.
- 5Origin and lab report. “Ceylon” is a name buyers seek. A report from NGJA, GIA, GRS or another lab confirms the stone, its treatment and often its origin.
Before you buy a gem
- Ask for a lab report and check its number with the lab. For a costly stone, have it tested yourself before you pay.
- Ask in writing whether the stone is heated or treated. Undisclosed treatment is the most common way buyers lose money.
- Watch it being weighed, and compare the weight and size with the report.
- Buy from a dealer with a National Gem and Jewellery Authority (NGJA) licence. Gems leaving Sri Lanka must be exported through the NGJA.
- Never pay in advance to someone you have not met for a stone you have not seen.
