The diamond depth refers to several aspects of the cut precious stone. If you don't want to spend all that much, but still want to create the impression of a large stone then a larger surface will help to create the illusion of a larger stone. This being said, a too shallow cut will mean poor light reflection whilst a too deep cut will have just opposite effect. It is thus important to get just the right diamond depthto ensure the perfect reflection of light back into the viewer's eye.
The ideal diameter is between 58 and 62% that means the stone should have a depth relation to diameter of around 59%. The so-called Tolkowsky cut ensures a brilliant reflection. It is however, more than reflection that makes up the value of the stone. The overall finish which includes the ideal symmetry, perfect polish, and the equally important proportions will ensure the perfect brilliance of the stone. Although cut is only one of the important four C's, it does play a significant role in determining the value of the finished product.
Unfortunately most of the time about 50% of the stone is lost during the cutting to ensure the perfect diamond depth and thus brilliance. The cut however, does not affect the price so much and it is thus up to the buyer to decide on the desired end result.
What is important to note is that the facets should be in just the right symmetry to ensure brilliance. If you want a faultless diamond depth contact us to ensure that you obtain not only a beautiful ring or garment, but also a stone that produces superior brilliance and fire.
