Helps distinguish natural diamonds from synthetic diamonds. THIS IS NOT A DIAMOND "TESTER"
- you must start with genuine diamonds, i.e. if you don't know
if you have a diamond, test it on a diamond tester first.

If you are new to gemmology I recommend the book Gem Identification Made Easy. Not only is this a good guide to gemstones, it also has details of every gem tester, including hints, tips and advanced instructions. For more details of this book, click here
- special discount price if you add a book when buying this item
Not as detailed, but good guide to gemstones, beautifully illustrated, is Gemstones.
The most basic item of equipment for any jeweller (and especially for buying diamond jewellery) is a jewellers loupe. The best loupe (apart from Zeiss) is the QUICKTEST 10X20, £27.50.
Even a beginner will be able to see if a stone is scratched on top and chipped all around the edges (or the edges are worn smooth) or if it is full of bubbles - it will not be diamond, you will not need a diamond tester!
