Triangles are chosen by side length and weighed by the carat. This chart covers single curved trilliants and straight edge triangles for patterns, clusters and accents, so you can plan the weight before you order. For side stones, see the pair chart. Every size is calibrated to ±0.15mm and sorted by hand under the loupe.
How many stones, how much weight.
Pick an outline and a size, then enter a stone count or a total carat weight. The other fills in.
Estimates only. Actual weight is confirmed on the scale.
Each row is a calibrated side length. The shape beside it is drawn to scale against the others. Weights are for a single stone. Switch outline to see its sizes, then select any row to load it into the estimator.

*Counts are approximate, based on standard calibrated single triangle melee, and vary with depth, the curve of the sides and size within the ±0.15mm tolerance. Scale shapes show relative size, not actual size on screen.
Side length is the spec
Triangles are calibrated by the length of a side. Order to the size your setter or CAD calls for, then use the weight column to plan the budget.
Curved or straight
A trilliant has gently curved sides, which give it a fuller outline and more spread for its size. A straight edge triangle keeps its sides flat, so it sits flush against the next triangle in a pattern or cluster.
Weight follows the make
Depth and the curve of the sides both move the weight, so two triangles with the same side can weigh differently. Counts here assume standard proportions. Every stone is a natural diamond, screened for natural origin before it ships.
How melee is sold
Retail orders are sold per the piece price shown. Trade orders are invoiced by the carat on the actual weight of your parcel, and we contact you first if the total differs from the estimate by more than 10%. Melee is final sale and not available on trade memo.
