Light maps are face-up and in diamond, unless a cut was designed for another stone. We draw every picture from the cut's own model.

Brilliants

Round brilliants cut to the proportions published in 1919, from the 73-facet round to our finest subdivision.

Jewelry cuts

The shapes jewelers set every day: fancy brilliants, step cuts and traditional patterns.

Elongated shapes

Longer than they are wide, from the oval and pear to the step-cut emerald and baguette.

Square shapes

As long as they are wide, from the princess and cushion to the step-cut Asscher.

Triangular shapes

Three-sided stones, with straight sides or softly curved ones.

Other shapes

The heart, the regular hexagon and octagon, and the sixteen-sided Portuguese Bird's Nest.

Historic cuts

The evolution of the brilliant in order, from the single cut to the 1919 round, rebuilt from primary sources.

House cuts

Our own designs, grouped by outline like the jewelry cuts. Each design is drawn for one gemstone, and its page says which.

Round shapes

Rounds on our own facet plans, eight-fold and twelve-fold, for diamond and moissanite.

Elongated shapes

Longer than they are wide: a stepped hexagon finished the same on both faces, and a deep marquise that shows the bow-tie.

Other shapes

Regular outlines and unusual forms: an eight-fold kite, a faceted cabochon and a hexagonal double point.

Platonic solids

The five regular solids: on each, every face is the same regular polygon and every corner is the same. We sell them as 3D models only. They share one circumsphere, so the set nests together at true relative size. A solid has no face-up, so it shows in 3D in every view.
