Awesome 19.93ct Nipomo Agate with Marcasite cabochon

Don't miss this collectors cabochon. Sometimes refered to as marcasite jasper, nipomo jasper grows in conjunction with marcasite and pyrite in high pressure areas creating these beautiful gems. The golden marcasite in this piece sits against the smokey gray nipomo like silver leaf, but it is one with jasper, and can be worn or displayed without worry. It measures an impressive 29.9mm x 13.7mm x 4.5mm and has a well polished glossy luster. Sourced from Indonesia. Untreated.
