The S.L. Bach Position Cut®

S.L. Bach

At SJI we consider ourselves diamond sculptors, not cutters. With that in mind, we are very proud to offer our signature series, the S.L. Bach Position Cut®, created by Steve Saitelbach, master lapidary.

The Position Cut features a precise alignment of facets above and below the girdle, designed to minimize light leakage and deliver exceptional luster, brilliance and fire. Steve cuts most Position Cut stones himself, and every one is cut to his specifications.

Our natural diamonds come from suppliers who comply with the Kimberley Process.

Whether the stone is a round brilliant or a fancy shape, the Position Cut is cut to show its brilliance and its size to their best advantage.

What Sets the S.L. Bach Position Cut® Apart

Every facet has a partner. In the S.L. Bach Position Cut®, each facet on the top of the stone is aligned with its counterpart below, meeting at a carefully faceted girdle. Working as one, they are designed to draw out the brilliance, fire and scintillation within the stone.

Exclusive Licensing

Imagine having the ability to sell your own signature cut diamond, exclusive to your establishment. Now you can! Licensing opportunities for our Position Cut Diamond Series are available. Please contact us for more information.

From rough to finished

Inside the Position Cut

Every stone is scanned, mapped and planned before a single facet is cut.
