The weight does not normally exceed a few carats Gems of about 10 carats are extremely rare and usually of an atypical, rather dark, unattractive color.
Distinctive features The color, single refraction, and luster are useful means of identification, but the physical properties have to be measured to distinguish it, for instance, from some hessonite garnets. Examination of the absorption spectrum can be very useful; where clearly visible, which is not always the case, it is distinctive.
