Of all possible colors for gem Zoisite, the typical brownish/yellow of unheated stones is generally the least desirable. That is, unless the stone is orientated and cut to feature the dramatic pleochroism the material is capable of. Zoisite is a rare trichroic gem material, creating the possibility of a gem like this, one in which browns and purples interplay with yellows and greens. As with many of our selections, this is a parcel selected gem, the one of many that shows this in a quite stunning way. Really superb cut, which is key here, sets this one off to perfection. Rare!
