OKD-375 Dioptase Altyn-Tube, Khirgiz Steppes, Kazachstan. Ex. Nancy Collins Collection. Previous older collection of unknown origin. This is a nice deep green dioptase specimen with some serious size. The individual crystals reach 2 cm in diameter, although most are closer to one cm each. They are gemmy with outstanding form and luster. There are two small regions on the display face that are scraped clean of crystals so it is not damage free. It does however still display very well and present itself as a substantial piece. It measures 10 x 9 x 4.5cm. A great specimen to add some color to a case. 3,800$
