A beautiful, gemmy and lustrous, dark teal blue, indicolite tourmaline crystal with a frosted, matte termination. This is CLASSIC, OLD material from the 1960s or early 70s, from the famous Jonas Mine of Brazil. This piece predates the incredible find of cranberry tourmalines in the late 1970s. This complete all-around crystal is essentially pristine, with only very trivial edge-wear on the termination edge and on one side. They are certainly not a detraction to this fine old-timer. The UNRETOUCHED backlit photo highlights the intense color saturation and gemminess. Ex. George Elling Collection. 15 grams.
