Now that is a big title for such a small stone, but it is true. This standard round brilliant only weighs .21 carats, but it is a chrome tourmaline and that means GREEN. Chrome is really a misnomer because it is usually colored by vanadium. And the tourmaline species is Dravite (not a brownish Elbaite) and that produces gemstones with a different visual impact than Elbaite, which is the principle producer of gemstones out of the group of minerals called tourmaline.
There may be other chrome tourmaline that match this stone in hue, but most chrome tourmaline has a darker tone level than the optimal. With this little gem, you get green, flash and a great tone level that makes a statement bigger than its small size.
