Locality: Santa Rosa mine, Itambacuri, Doce valley, Minas Gerais, Southeast Region, Brazil
This gorgeous and UNREPAIRED, 3-dimensional, complete-all-around cluster is a historic example of classic multicolored tourmaline from the famous Santa Rosa Mine. It is noted for the gradation of blue-green hues. It looks a bit dark in the pics, and does need some backlighting, but not that much. it has not been shot with any special tricks, in other words. Note its publication in an article detailing exciting new finds of gem crystals from the mid 1970s!
7.4 x 3.5 x 2.1 cm
