20hhgd.is ((QUARTZ, FELDSPAR)), $10 MINIMUM BID, Location unknown, 8 x 7 x 6 cm, Cabinet | |
Renaud Vochten collection # 8813-19 but no label with te Davidson collection. I think this is called Graphic Granite with interplay of Quartz and Feldspar. I am no sure on the black area is but appears to be thin. It is probably a rare and valuable species. ex Glenn Davidson collection. ex Ranaud Vochten collection. |
