3.1" Lustrous Black Garnets with Blue Calcite - Mexico
This is a gorgeous association of black-brown garnets and blue calcite. When collected, the garnets were completely encapsulated in calcite and have since been exposed by acid etching. This specimen was labeled as coming from Mexico, however we have not been able to independently verify this.
It comes with an acrylic display stand.
