Botryoidal chalcedony in microcrystalline quartz - 114g | PCGRAP-35

If you are looking for a rare and unique mineral to add to your collection and join your other wonders, here is our selection of botryoidal or grape chalcedony, mistakenly called grape agate (no, it is not an agate at all!).

Hailing from the island of Sulawesi, in Indonesia, botryoidal chalcedony is formed of quartz crystallites that strangely resemble a bunch of grapes. Primarily purple in color with some light to very dark shades for the rarest ones, white, gray, or green botryoidal chalcedony can also be found.

Characteristics of botryoidal chalcedony:

• Length: 10cm
• Width: 5.6cm
• Height: 3cm
• Weight: 114g
• Chalcedony hardness: 6.5 to 7 on the Mohs scale
• Variety of chalcedony in microcrystalline quartz form

Aspects of grape chalcedony:

Here is a particular botryoidal chalcedony of beautiful size but with very few grape-shaped crystals. It is mainly composed of green, purple, and linen gray quartz microcrystals. Some grains are present on a part of the stone. A translucent stand will be offered with the chalcedony so that it can be carefully placed on it.

Note: Particular care has been taken to best respect the natural colors of the minerals offered to you. The photos are taken in the best conditions, and slightly retouched to best resemble the original stone. However, there may be slight contrasts due to the different screens used and their brightness.
