ROUGH DIAMOND

A rough diamond is a diamond rock which has not been processed. They are available in a variety of naturally shapes including octahedrons, cubic and triangular.

There are two types of rough diamonds, gem quality and industrial. Technically, there’s a third, but they are really just the poorest quality industrial diamonds which end up as dust in polishing applications.

Rough diamonds usually resemble piece of light colours glass. They often have an oily image and don’t sparkle. Very few rough diamonds are actually gem quality. Only those with the very light colours, or are colourless will pass the test.

Rough diamonds are becoming increasingly popular for use in jewellery. The problem is that it is not always easy to separate a rough diamond from things like quartz or maybe colours glass without knowing what to seem. rough diamond can be scratched by anything aside from another diamond, then it is fake.

The other mineral most frequently thought to be diamond is quartz. The only mineral you can really use to check the hardness of a diamond may be a piece of corundum. Corundum is that the mineral which makes up ruby and sapphire, and only diamond is harder. If the rough diamond on offer can scratch the corundum, then it’s surely a diamond.
