Diamond and Moissanite Information
Diamond stones
In today’s market everything with an expensive price tag such as Rolex watches, Versace clothing and even diamonds, will all have imitations. The main problem caused by imitations is the worry of being fooled in to paying a high price for a fake. With diamonds there is a solution which is a diamond tester.
Diamond is a pure carbon, formed around 30 or 40 millions years ago. It is the hardest natural material known to man. When buying diamond there are four main qualities to look for, colour, clarity, cut, and carat weight (These basic qualities are commonly known as the four C's).
Moissanite stones
Moissanite is the newest and best diamond simulation on the market which not even diamond testers can tell it is an imitation. Now that it has been introduced into the world market it has created a new danger to everyone involved in the diamond jewellery business.
Moissanite may be a fake stone but they are still not a cheap stone. Moissanite stones are so much like diamonds that they can easily be sold as natural diamonds. The Moissanite stone fails when it comes to natural materials as it lacks a natural element that only diamonds contain. There are now new testers which are specifically designed to test for Moissanite stones.
How to examine and test a diamond
Never try and tell if a diamond is real or not using just the naked eye. Here are the common main ways to examine a diamond accurately.
Microscope / Loupe / Eyeglass: Examine using a standard 10x magnifying glass called a jewellers loop. This enables someone to see the 4 C's in stones a lot more clearly.
Diamond / Moissanite Testers: A diamond tester uses light to verify that the stone you are examining is really a diamond. A Moissanite tester works on different principles to diamond testers but is a must in today’s diamond market.
