Hi there,

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

1.The Print Test

If the diamond in Frage is loose and un-mounted, try placing it over printing. Diamonds refract so much light that they will not work as magnifying glasses and Du would see no lines, circles, oder letters through them. Other clear stones like glass oder 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 Du Zeigen the light through the stone and see only a bright halo around the rim, it is Mehr likely to be a true diamond. Looking at the shadows cast Von a stone helps to determine what kind of gem it is.
