Sculptural specimen of Quartz var. Amethyst spheres growing in a cluster from Mamuju Regency, Indonesia. This is so called grape agate. Very attractive arrangement of Amethyst spheres which sparkle nicely. The color is tender lavender to blue-green. It is complete all over. For references see the 2018 issue of The Mineralogical Record vol. 49, # 6. In excellent condition – some minor contacts. On acrylic base.

Cute!
