The Hearts & Arrows Pattern, achieved in every Diamond Nexus gemstone, is the product of our ultimate quest for beauty. The hard science and laboratory research that is done by our technicians has one singular result: the creation of a tremendously hard crystalline material with virtually identical optical properties to a mined diamond. However, our labs produce the same thing that mother nature does when creating a diamond; a rough, uncut, raw stone. To release the fire, brilliance, and beauty of the stone requires the artistry of a world-class gemcutter.

A perfectly cut gemstone refracts light in a very specific way. If the faceting angles and transitions exactly match the Ideal Cut Formula, first set down by Marcel Tolkowsky in 1919, the stone will refract a dazzling pattern when viewed under a diamond scope: "Hearts and Arrows" for a Round Cut and 'Starred Cross" for a Princess Cut. In the diamond world, less than 15% of all diamonds reach the Ideal Cut Standard. That is why true "Hearts and Arrows" diamonds are priced at such an incredible premium.

At Diamond Nexus Labs, all of our gemstones achieve the Ideal Cut Standard and will display flawless Hearts and Arrows and Starred Cross patterns. We simply cannot call ourselves strivers for perfection and offer anything less.
