Diamond Pointers

Sounding like a diamond expert can be a lot easier with a few basic terms.   The 4 C’s, Cut, Clarity, Color and Carat are the basics which we’ve discussed at length in previous blog posts.  But another piece of terminology that diamond pros use are “points” or “pointers”.


When diamond experts refer to diamonds, they will call it a certain number pointer like “a 50 pointer” or “a 75 pointer”.   This number does not refer to the amount of different flat surfaces (also known as facets) on a diamond.   The number relates to the amount of carats in a diamond.   From a mathematic standpoint, 1 carat equals 100 points.   So if someone calls a diamond a “50 pointer” they are saying the diamond is half a carat.

As discussed previously, the amount of carats does not refer to the size of a diamond, but to the weight of a diamond.   One carat equals 1/142nd of an ounce or 1/5th of a gram.

As discussed previously, carat weight is not the key component of a diamond.   The diamond’s cut has a lot to do with how it sparkles.   The diamond’s color, whether a white diamond or a fancy color diamond relates to it’s beauty.   The diamond’s clarity relates to whether it has any cracks or inclusions within the stone.   It is these four factors combined that dictate a diamond’s true value.

So you may never become a diamantaire with your own personal loupe in your back pocket, but you can at least sound like one.
