The botryoidal crystal behavior is attention-grabbing equally for its distinctive condition, and The truth that it is usually adopted by quite a few fairly distinctive minerals. The phrase is derived within the Greek phrase botrus, meaning "bunch of grapes", and refers to little crystals occurring in carefully interlocking spherical masses or "bubbles" which often appear like bunches of grapes.
Several species and kinds commonly undertake the botryoidal habit, like some types ΧÏυσά of chalcedony, hematite, goethite, fluorite, malachite, chrysocolla, azurite, jade and prehnite.

Botryoidal crystal formations may be rather putting and are well-liked with mineral collectors. Botryoidal gems are fashioned into cabochons, carvings or ornamental objects and infrequently Display screen interesting patterns. There's a broad variation in visual appeal, based ΧÏυσά upon whether or not the bubbles are large or small, uniform or various sizes In the event the botryoidal surface area is confined to recesses or not, and whether the surface area is covered with drusy crystals. Moreover, gem cutters can handle the fabric in alternative ways. Often the botryoidal floor is still left in its normal condition and at times it really is polished to ensure some or each of ΧÏυσά the bubbles are flattened to reveal the inner layering.
