† Calculated estimate from nearby published sizes. Below the smallest reference, dimensions are scaled assuming unchanged proportions. These entries describe an illustrative size, not a measured stone.

Educational estimates. Carat measures weight: 1 ct = 0.2 g. Depth, girdle and proportions affect dimensions, so there is no exact mm-to-carat conversion. Check the individual stone’s measurements and grading report.

Character & construction

Expressive by design.

A cleft, paired lobes and a tapering point form a recognisable silhouette. The balance of these features is central to its appearance.

What to consider

Pay attention to matching lobes, a distinct cleft and protected point. This is an educational example; ask us about sourcing availability.

Ask for the actual measurements, report and images of the stone being offered. A shape illustration cannot establish its appearance, grading or availability.
