Hi there,

If Ты want to determine whether your diamond is real или fake, there are a few easy tests Ты can do without any special equipment.

1.The Print Test

If the diamond in Вопрос is loose and un-mounted, try placing it over printing. Diamonds refract so much light that they will not work as magnifying glasses and Ты would see no lines, circles, или letters through them. Other clear stones like glass или crystal will reveal the print clearly.

2. The Light Test

A similar test uses a small light, such as one that can be carried on a key ring. If Ты Показать the light through the stone and see only a bright halo around the rim, it is еще likely to be a true diamond. Looking at the shadows cast by a stone helps to determine what kind of gem it is.

I read these ideas at thediamond.com which have helped me immensely in identifying the uniqueness of my diamond jewelry.
