Brazilian Agate: Brazil produces most of the agate mined in the world bringing all types and colors to the market. Brazilian Agate is often found with a multi-colored border creating a fascinating variety of specimens, such as this piece with borders of mauve, intense reds and golds, surrounded by black. Those with solid crystallization, such as this, are highly prized. In this specimen several different crystal structures can be seen growing toward the center, some tinged with gold. The surrounding border of black suggests the volcanic origins of Brazilian Agate. The artist has employed a myriad of colors and crystal structures in the creation of this unique work of art.
