This extraordinary material is as sought after as it is hard to acquire. When we first saw the Mahenge production we were concerned it may not match the fine cobalts of other localities - but rest assured after we saw this parcel we were convinced! Stones are almost always very small and irregularly shaped - every tiny of bit of weight in a finished piece is serious money. There are two qualities here that we almost never see - firstly, a gorgeous top color stone and, secondly, a correctly proportioned and fresh precision cut. Just a few short thin needles visible under 10 magnification. Remarkable color.
