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 being the red-brown sagenite crystal clusters. These agate specimens from Freddie Quarry in California often contain metallic marcasite that can be found throughout the agate.
