This gemstone sphere boasts a unique banded and layered design, crafted from polished agate. The smooth, polished finish adds a touch of sophistication to any collection, making this the perfect addition for any crystal enthusiast. Agate is formed when Volcanic lava bubbles cool and slowly fill with crystalline bands, making the Agate incredibly natural & unique. It’s a mineral that has been cut, polished and then dyed to accentuate the stunning natural patterns within!
