GREEN TOURMALINE (BRAZIL) – SUGARLOAF/CAT’S-EYE CABOCHON 2.97 CT.
This vibrant green sugarloaf cabochon shows a strong cat’s-eye effect. The cat's-eye doesn't show well in the accompanying photographs (special lighting is required) but it is very noticeable in the hand. The stone was cut from tourmaline mined at Brazil’s famous and long-depleted Morro Redodo deposit. It weighs 2.97 ct. and measures about 8.8 x 7.5 x 5.7 mm. Cat’s-eye gems depend on internal inclusions to create the moving “eye” optical effect. In tourmaline the inclusions are generally hollow tubes that sometimes show here and there on the stone’s surface, as in this case. They are a very minor detraction from the stone’s great color and overall appearance. October birthstone. (All uses, N).
