  • Natural – Also known as Indented Natural.

A natural is an inclusion that extends into the diamond from the surface. The natural can be a portion of the original surface (or skin) of the diamond (rough) or an opening left when a surface-reaching crystal is worked during polishing.

  • Needle – A thin, elongated crystal inclusion, which literally looks like a needle. 

A diamond’s clarity grade refers to how include (i.e. blemished or flawed) or not a diamond is. A needle is an inclusion in the stone. Any inclusion will always have a negative impact on the value of a stone. However, different inclusions detract different amounts and the location of the inclusion is also important. Any flaws that are highly visible are worse than flaws that are located on the edges of the diamond, and that may be able to be hidden by a prong in the setting. While you can treat diamonds for certain types of imperfections (namely color and clarity), this not always advised as treated diamonds sell for less than non treated diamonds.

  • Nick – A small notch on a facet junction (usually on the girdle or culet).

Any damage to a diamond will detract from the price. It may be possible to recut the diamond to remove any damage, however you will lose carat weight in the process which is not ideal. While diamonds are the hardest substance on the planet, it is still possible to damage them. Having your diamond correctly and professionally set in jewelry that will minimize damage as well as keeping your diamonds in lined jewelry boxes are good steps to follow. These will keep your stones in the best possible condition
