Diamond Depth

Diamond Depth

If you are interested in what makes a great looking diamond, it is important to consider the depth of the stone. Depending on the cut of the stone, the depth can vary. Depth not only can give the illusion of a bigger stone on a ring, the depth of the stone can also determine the amount of light that is reflected back to the eye. Here are some tips.

For many people buying a diamond, a larger surface area is an attractive way to give the illusion that the stone is much bigger than reality. Diamonds are extremely expensive and if a buyer can save a few thousand dollars while still getting a stone with lots of surface area, it might seem like a good idea.

It is important to note, however, that the way a diamond is cut, and specifically the depth of the diamond will determine the amount of light that is reflected back to the viewer’s eye. Too shallow a stone and the light will pass through it, too deep of a stone and the light is lost as well. If you want to get the most out of your diamond, the depth of the stone in the relation to the diameter should be 59.3%. 

One of the most popular diamond cuts is the Tolkowsky’s cut. The Tolkowsky’s cut will reflect light optimally from the stone to show its brilliance. The Tolkowsky’s cut makes the depth of the stone 59.3% of the entire diameter of the stone. There are mathematical equations to figure out the depth and degree of your stone, but when purchasing a stone, you can talk about the depth of the stone with the jeweler. Most diamonds are cut to specific dimensions and your jeweler can discuss the specific cut your diamond has. However, if you are planning on purchasing a diamond, it is important to note that the depth of the diamond does affect its reflective qualities.
