GRAPE CHALCEDONY - Indonesia

'GRAPE CHALCEDONY'

Mamuju, Sulawesi Province, Indonesia


A remarkable variety of quartz that forms in globular aggregates resembling a bunch of grapes.

It is most commonly known as grape chalcedony (or grape agate) but it could equally be called amethyst due to the fact that the surface of the 'grapes' consists of tiny mauve-coloured quartz crystals that sparkle in reflected light.

Specimens of this material only came on the market in 2016.

Both sides of this specimen are covered with these beautiful crystal aggregates which look amazing under a hand lens.
