2.8" Polished, Sumatra Flame Sagenite Agate Slab - Indonesia

This is a gorgeous, 2.8" wide slab of Indonesian "Sumatra Flame" Sagenite Agate. It has been polished to a mirror like finish on all sides and features sagenite crystal formations scattered throughout agate.

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 golden sagenite crystal clusters.

Sagenite is a name that often refers to acicular rutile crystals, which in this case is accurate. The golden crystals within this specimen are technically rutile (TiO2) crystals.
