Ever seen a mineral that grows in bunches? Grape agate forms rounded purple beads stacked into clusters, and it is one of the easiest specimens to fall for.
Its proper name is botryoidal purple chalcedony, and the round, bubbly surface is exactly what that word describes. Grape agate is usually purple but can carry blue, white, green or gray grains, so take a close look at the photos to see the mix on this cluster. At 5 inches it fills the palm and holds its own in a cabinet next to larger specimens. It is a strong choice for a collector building out a quartz family shelf or for anyone who loves purple. This is the exact grape agate cluster shown.
Measurements are about 5 by 4 by 2.5 inches, and it weighs about 355 grams. A ruler photo is included.
Grape agate is botryoidal chalcedony, microcrystalline quartz that grows in rounded clusters; botryoidal comes from the Greek for bunch of grapes. Its purple color is attributed to trace iron, and despite the trade name it is not true agate, since it lacks agate banding. It comes from the Batu Manakarra mining district of Sulawesi, Indonesia, a relatively new find.
Stone Meaning: Grape agate is traditionally associated with calm and inner reflection.
