Improve the sparkle of underperforming diamonds by 50-100%. Sparkle Cut Technology’s proprietary, microscopic groove process is accepted by major labs and dramatically increases the sparkle of a diamond without changing it’s weight or characteristic core.

How Sparkle Cut Technology Works

A proprietary algorithm determines the location, number, and depth of the microscopic grooves to be applied.

A focused ion beam creates the microscopic grooves, which redirect light to the table of the diamond, creating more sparkle.

The invisible, microscopic grooves do not change the carat weight, color, clarity, or overall diamond grade,
