Moissanite and Carat
Moissanites are commonly referred by their dimension rather than carat.
This is where DEW (Diamond Equivalent Weight) comes in to play.
In short, if you were seeking prices for a 1ct Moissanite, we would quote you for the 6.5mm (or 6mm) option.
* We say approximately as the weight can be affected by how it is cut (ie shallow, deep etc)
