External Diamond Features

There are many different types of blemishes that you might find on the surface of a diamond, or read about in a grading certificate. Some diamond blemishes are a natural part of the stone and others occur when the gemstone is cut and polished, when being stored with other diamonds (paper wear) or during day to day use in Jewellery.

Surface blemishes can affect diamond clarity, and value, but many blemishes have little or no affect on a diamond's appearance.

Scratches are usually fine surface lines that can be polished away. If you have a scratched diamond, we will be pleased to estimate for polishing.

Nicks are areas where a portion of the diamond has chipped away. Small nicks are sometimes repaired by polishing them to create an extra facet.

Pits are holes in a diamond's surface. Some pits aren't noticeable, but a pit on the diamond's table facet is more likely to be visible, and can affect the diamond's clarity grade.

A natural is a portion of the diamond's original surface that hasn't been polished. Naturals are sometimes left along a diamond's girdle if doing so allows the cutter to produce a larger cut stone. Naturals don't normally impact the diamond's clarity grade if they are confined to the girdle.

A trigon is a natural that looks like a small triangle,
or triangles within triangles see image to left.






Polishing lines
are sometimes left over from the cutting and polishing process.

Extra facets are created to remove blemishes and can have a detrimental effect on the diamond's appearance and value.
