Grape agate is the commercial trade name for a rare, unique form of botryoidal (grape-like) purple chalcedony, a microcrystalline variant of quartz.

The most sought-after variants range from soft lilac and lavender to deep dark purple. The color arises from traces of iron and manganese within the crystal structure. Sometimes the spheres have a microscopically thin layer of sparkling crystal points, which creates a beautiful 'druzy' glitter effect.

Unique origin: The vast majority of high-quality grape agate was only discovered around 2014 and is exclusively mined in the Mamuju region on Sulawesi Island in Indonesia.

The mineral forms deep inside the cavities of volcanic rock (andesite). For millions of years, silica-rich fluids have deposited in layered fashion around a central point, forming perfect spheres.
Hardness: It scores 6.5 to 7 on the Mohs scale. The loose spheres, however, can be fragile and break off with rough handling.
