Jade, Dia: 9 5/16 in. Th: 3/8 in. Exposure to minerals such as alkali and iron oxide create the pale blue to white and rusty oranges present in this bi disc. Peering out through the fatty appearance of the matte white colorations are deep greens and blues, creating stark contrast. This piece is in very good condition with very few chips or scratches and ships with a custom made steel display base.
