It is Yehuda’s proprietary process that takes a diamond with a visible imperfection and makes the imperfection invisible to the naked eye. The imperfection remains in the diamond but it can no longer be seen. A more technical explanation would be the following:
During the Yehuda clarity enhancement process a microscopic amount of material is inserted into the part of the diamond that contains a feather. This material has the same optical properties as the diamond itself. When light travels from one medium to another, it either changes its course or reflects in a different direction. When light attempts to pass through a non-enhanced diamond that has a feather, the light hits the feather and reflects off in any number of directions. That is why we see the feather, and the diamond doesn’t appear to be clean. With a Yehuda diamond, the light passes through the natural feather because the material used for the enhancement has the same optical characteristics as the diamond. The beam of light “thinks” it’s still traveling through the same material (diamond) and continues its original course.
Who Invented This Clarity Enhancement Process?
In 1982, Zvi Yehuda, an extremely famous Israeli scientist discovered a way to enhance the clarity of diamonds. The revolutionary process optically eliminates “feathers”, which are naturally occurring in most diamonds. The result is a more visually stunning diamond that you can purchase for significantly less than a similar-looking, non-enhanced diamond. Best of all, Yehuda Diamonds are totally natural and come from the same diamond mines as all other diamonds. The clarity enhancement process is not visible to the naked eye. Only a trained jeweler will ever know that you own a natural Yehuda Clarity Enhanced Diamond.
Does Clarity Enhancement “Change” A Diamond In Any Way?
No, it is still a natural diamond – it just looks better. The amount of material used to fill the feather is so microscopic that even the world’s greatest diamond laboratory, the Gemological Institute of America (GIA) has reported that Mr. Yehuda’s clarity enhancement process adds ZERO WEIGHT to a diamond. Take a look at the before and after pictures below and judge for yourself.
Do I need to take care of my Yehuda diamond differently than other diamonds?
Absolutely Not. The Gemological Institute of America (G.I.A), after extensive research, has determined that normal wear and tear cannot harm the enhancement. Only if the Yehuda diamond is exposed to high heat or strong acids and bases, the enhancement may be reversed. In the extremely rare case that a Yehuda Diamond should lose its enhancement, the Yehuda Diamond Company will re-enhance the diamond at no charge, no questions asked. With each diamond sold, Yehuda provides a unique business card-sized CD, which when played on a standard PC, describes the Lifetime Guarantee.
Every Clarity Enhanced Diamond sold by Yehuda Diamond Company has a built-in signature “Flash effect” that can be seen under normal 10X magnification. The flash effect appears as a line of vivid color at the location of the enhancement.
As a result, we can offer you visually stunning diamonds for the price of 20-30% less then similar looking non-enhanced diamonds. You can either save money or purchase a bigger, more beautiful diamond.
