Clarity Enhanced Diamonds

A clarity enhanced diamond is a natural diamond that has been treated for its imperfections (known as “feathering”) using a treatment known as the Yehuda treatment to enhance the clarity of the diamond.

Contrary to popular believe diamonds are not created from coal but are created from carbon that is found in carbon-containing minerals, and formed at a pressure of 400,000 pounds per square inch that only exists at depths of 87 to 120 miles in the Earth's crust.Growths of diamonds occur over 1 billion to 3.3 billion years.  The diamonds are then brought close to the Earth's surface through deep volcanic eruptions that become igneous rocks known as kimberlites and lamproites. Since diamonds are created under such pressure, it is only natural that diamonds would have various imperfections (also known as “feathering”) called inclusions or flaws and blemishes.

Therefore, to enhance a diamond's clarity in 1982, Zvi Yehuda, an Israeli scientist, discovered a way to enhance the clarity of diamonds by inserting into the diamond's structure a microscopic amount of a special material that has the same optical properties as a diamond by using an infrared laser.  The process, known as the Yehuda treatment, makes the inclusion invisible even to the highly magnifying jeweler’s loupe. (The diamond is the same, and the inclusion is still in the diamond, it just cannot be seen.)  In the end of the completed process, the enhanced diamond will reflect light (known as sparkle and brilliance) the same way a diamond of a higher clarity diamond would. Furthermore, the Gemological Institute of America (GIA) says that this process was “found to be effective in improving the appearance of most of the samples examined...”[1].
