In buying something there are things which you should consider. Whatever those things are of course the first thing you will check is the quality of a product.

How clean a diamond is reflects with its clarity. Whether if it has no blemishes or any insertions whenever it will be observe by the eye or by a magnifier.

To select a good quality when buying a diamond you should be familiar of some terms.

The blemishes which I have mentioned earlier are flaws on the surface of a diamond. If there's any missing piece that is what we call 'CHIP' and any scrape is what we can consider a 'SCRATCH.'

Any crack found is considered as a 'FRACTURE'. Sometimes during polishing stage there are fine lines being left which is called 'POLISHING LINES.' While the 'NATURAL' is the unpolished part.

In polishing a diamond you may encounter an 'EXTRA FACETS' which shouldn't be present. These are excess polished surfaces which messes up the symmetry of a diamond.

'BEARDING' on the other hand are tiny fractures that can be found on the edge of a diamond.

'INCLUSIONS/INSERTIONS' are some imperfection which may be found inside it.

If you happen to find black spots inside the gem it is 'CARBON', while a white spot i s called 'CRYSTAL'. An internal cracking is called 'FEATHER.' Tiny spots called 'PINPOINT' happened to be smaller than a crystal and a group of it is identified to as 'CLOUD' that gives large inclusion.

The instrument used to estimate a diamond is 'LOUPE.' Such instrument must be 10X magnification. The housing surrounding the lens must be black to avoid distorting the color.
