Trapezoids are chosen by length and width, weighed by the carat, and set in pairs to flank a center stone. This chart gives the weight of each matched pair and of a single stone, so you can plan a three-stone ring before you order. Every size is calibrated to ±0.15mm and sorted by hand under the loupe.
How many pairs, how much weight.
Pick a size, then enter a number of pairs or a total carat weight. The other fills in.
Estimates only. Actual weight is confirmed on the scale.
Each row is a calibrated size, length by width. The shape beside it is one stone, drawn to scale against the others. Weights are given for the matched pair and for a single stone. Select any row to load it into the estimator.

*Weights are approximate, based on standard calibrated trapezoid step cuts, and vary with depth, short side length and dimensions within the ±0.15mm tolerance. Pair weight is the total for two stones. Scale shapes show one stone at relative size, not actual size on screen.
Length and width are the spec
Length is the long side, the one that sits against the center stone. Width runs outward from it. Order to the length and width your setter or CAD calls for, then use the weight columns to plan the budget.
Matched in pairs
Trapezoids flank a center stone, one on each side, so they are matched as a pair for size, color and make. Weights on this chart are for the pair. Each stone weighs about half.
Weight follows the depth
A step cut carries its weight in depth and in the length of its short side, so two pairs of the same length and width can weigh differently. Every stone is a natural diamond, screened for natural origin before it ships.
How melee is sold
Retail orders are sold at the 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.
