First Diamond Group has developed a new clarity enhancement treatment that it says replaces traditional laser drilling. The company says that its new treatment leaves no surface-reaching drill hole, removes black and dark inclusions permanently, and is guaranteed for life. Suitable stones range from .50 cts. in all shapes and colors. Cost for the treatment is $150 per carat. For information, contact First Diamond Group via e-mail at weisbrot@internet-zahav.net.
