How to read this chart
- Carat
- A carat is a unit of mass: 1 ct equals 0.2 g. A stone's actual moissanite weight can be measured on a calibrated scale.
- Weight per stone
- Hand-cut stones of the same nominal size can vary in weight. We therefore do not publish a single per-stone weight; order by the listed millimetre dimensions.
- Size
- Buy and fit by the millimetre dimensions. Every lot is calibrated to ±0.1 mm, stated in writing. For elongated shapes the size is written length × width. Three-number trapezoid sizes are shown in the same order as the live product variant — please confirm orientation with us before cutting a seat or ordering a matched pair.
- Price
- Round is sold by the 1-carat bag; the stone count per bag is the estimate shown on the live product variant. All other shapes are sold per stone. The two are never mixed in one column.
- Melee
- The jewelry trade's word for small calibrated accent stones in this size class — a word for the use, not a fixed carat boundary. Most buyers search for loose moissanite stones; same goods, different vocabulary.
