Swiss Coffee Stone Cabochon
Exciting new material! Richly dark and bold layers of brown swirled together, it’s almost mesmerizing. This piece was cut parallel to the layers in the rough since there was no “folding” creating the zebra-striping that is common for this material.
Polished to a vitreous (glassy) luster on the dome and sides. Flat, semi-polished back with a beveled edge for ease of setting. You will receive the exact gemstone shown in the pictures.
