A gorgeous 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 strongly. The color is rich lavender to green. It is very fresh. It is complete all over with small contact points. For references see the 2018 issue of The Mineralogical Record vol. 49, # 6. In very good condition – some small contacts.

Beautiful!
