Diamalite V1 is a custom cut cubic zirconia core with a DLC surface enhancement. 
The entire surface of Diamalite V1 is completely coated with Diamond like carbon (or "DLC"). Carbon-to-carbon bonds are defined by their hybridization. SP3 bonding is found in diamonds and the SP2 bonding is found in graphite. DLC has a variety of bonds and one of the defining properties of DLC is the multitude of bonds, particularly the SP3 to SP2 ratio. The greater the proportion of SP3 bonding in a DLC film, the closer its properties will gravitate towards true diamond-likeness. Diamalite V1 has a significantly greater ratio of SP3 to SP2 bonds. This distinction is what makes the Diamalite V1 the best diamond simulant on the market today.

If you want more fire for a pair of earrings or a pendant, we recommend Diamalite V2.
