Very nice, quality Mexican coconut geode pair! This geode contains a clear to very light blue quartz lining - the clear quartz lined coconuts are less frequently seen than the smoky or lavender, sometimes amethyst ones. There is also some light blue agate in the shell. Numerous crystals of an iron mineral, likely either goethite and/or todorokite, are found upon the quartz lining. Evenly opened with a soil pipe cutter into two halves and the edges are not polished. Price is $50.00 plus shipping.
