Which term describes an early cushion-shaped brilliant cut with a high crown, deep pavilion, 58 facets, and a large culet?

• A. Rose Cut
• B. Old European Cut
• C. Old Mine Cut
• D. Planner

Answer: (C)

An antique cushion-cut diamond described as a cushion-shaped brilliant cut with a high crown, deep pavilion, 58 facets, and a large culet is characteristic of the Old Mine Cut. This combination of shape and proportions defines that early cushion-brilliant style: the cushion form is square-to-rounded, the high crown and deep pavilion steer light paths deeper into the stone for a distinctive, bold sparkle, and the 58 facets reflect the older facet pattern used in mine-cut traditions. The large culet is a hallmark feature of this cut, giving a visible bottom facet that was common in this era. This set of traits helps distinguish it from other cushion-like antique cuts, such as the Rose Cut (which lacks a pavilion and many facets) or the Old European Cut (which has different proportions and culet sizing). The term listed as Planner isn’t a recognized cut term.
