What Is an Old Mine Diamond?

An old mine diamond is one that has been cut in a manner consistent with 19th century jewelry design. It resembles the modern cushion cut.

History

Old mine cut diamonds were procured from India in the 1830s. They were hand cut until the early 1900s. No two diamonds had the same cut.

Features

The old mine cut diamond has a high crown (top section) and a small table (top surface). The girdle (the area between the crown and pavilion) is round to rectangular, the cutlet (bottom surface) facet is large, and the pavilion (bottom section) is deep.

Settings

Old mine cut diamonds are commonly featured in Victorian-, Georgian- and Edwardian-styled engagement rings.

Rival Cut

The old European cut was popular at the same time as the old mine cut. Both have a similar shape, but the old mine cut has a lighter crown and a larger table.

Purchasing

Old mine cut diamond rings are rare. You're most likely to find one at an antique dealer or estate sale. Modern rings that re-create the old mine cut and antique setting are available through online retailers.
