Botryoidal crystal formations is usually really placing and so are well-liked with mineral collectors. Botryoidal gems are fashioned into cabochons, carvings or ornamental objects and sometimes Screen intriguing ΔαχτυλίΔια patterns. There's a vast variation in visual appearance, based on if the bubbles are massive or modest, uniform or unique dimensions Should the botryoidal surface is confined to recesses or not, and whether or not the ΧειÏοποίητα ΔαχτυλίΔια surface is covered with drusy crystals. In addition, gem cutters can deal with the material in different ways. Occasionally the botryoidal surface is left in its all-natural state and occasionally it truly is polished to ensure some or every one of the bubbles are flattened to reveal the internal layering.
