Purple grape agate, Indonesia

A cluster of tiny little spheres of grape agate from Sulawasi, Indonesia.  Just like actual grapes in both shape and colour, this mineral naturally occurs in both green and purple, and occasionally a single specimen shows both colours!  Mounted on a wooden base.

5/8 inch (1.6 cm) wide, 7/16 inch (1.1 cm) deep and 3/8 inch (0.95 cm) tall.
