NIPOMO SAGENITE AGATE FOR SALE

Sagenite agate is a formation of agate that contains acicular (needle-like) formations of fanning sagenite crystals that have been encapsulated in a mass of pseudomorphic agate. This occurs when agate fills a cavity within rock that had prior formations of minerals, in this case the red-brown sagenite crystal clusters. These agate specimens from Freddie Quarry in California also often contain metallic marcasite.
