Inclusions & Blemishes

Diamond extra facet on a GIA Certificate

If you are not quite sure why you are reading a post about extra facets on a diamond, I advise you to take a little step back in the series (OK not a little, right back to the start), so you can get up to speed on what inclusions matter, where you might find them, and what they might mean for your potential ring.

What is an Extra Facet?

Extra facets are pretty much what you’d expect, to be fair. Think of it this way; if ‘facets’ are those teeny tiny ‘faces’ or angles on a diamond, then extra facets are just additional facets/face/angles on top of the usual number needed for the stone to be characterized as a round/asscher/emerald/cushion cut etc., etc.

“Should an extra facet be a deal-breaker for me?” Well, although extra facets can occasionally mess with the symmetry of the diamond (but only minimally so), there is almost always a very clever reason for them to be there. Extra facets are a fantastic way to get rid of original unsightly blemishes, while making the stone even more sparkly! In fact, these facets are so chill, that they are not even considered when a diamond grader is determining the grade of a stone.

So instead of getting your pants in a twist if you see ‘extra facet’ on that diamond grading report, think of that clever diamond cutter who transformed that stone from ‘OK’ to ‘DAMN, YOU FINE!’
