When
buying colored gemstones, it is sometimes easier to evaluate the unseen
stone sizes by comparing them to diamonds cut to similar, standard
sizes. For example, if you wanted a colored stone the size of a two
caret marquise diamond, according to the chart below you should look
for a stone approximtely 12mm x 6mm. Chances are the stone won't WEIGH
exactly two carets, but it will be the same SIZE as a two caret diamond.
