Beautiful, gemmy and lustrous, teal-blue apatite crystals to 7 mm totally cover the front and the edge on this striking specimen from a most uncommon Brazilian locale - Campina Grande in Paraiba State. The matrix itself is very noteworthy, being a pearlescent layered box-work of feldspar peppered with gemmy, yellow-green hydroxylherderite microcrystals. Very rare and excellent material from this rare locality from the Marty Zinn Collection #6335.
