Pale Green Fluorite Cubic Crystal Cluster

This charming specimen displays classic cubic fluorite crystal form in an interlocking cluster of semi-translucent, pale yellow-green crystals. The natural cleavage planes are beautifully expressed across multiple faces, catching light with a glassy vitreous luster. Small inclusions and iron-oxide staining dots of warm amber punctuate the otherwise clean, cool celadon hue, adding natural character and depth. The overall form is compact and chunky, presenting well from multiple angles with visible cubic geometry throughout. Fluorite is a calcium fluoride mineral that forms in hydrothermal veins and often associates with metalite ores, granite intrusions, and limestone contacts. The Azusa, California locality in the San Gabriel Mountains is known for producing fluorite in association with skarn and contact metamorphic zones tied to the region's complex igneous history. The pale green color is caused by trace impurities and lattice defects, and fluorite from this area can occasionally exhibit fluorescence under UV light — a property so distinctive that the word 'fluorescence' itself was coined in honor of this very mineral. This specimen comes from Brian's traded collection at Iron Mountain Ranch — a California classic that complements the Okanogan Highlands material with a slice of Southern California mineral heritage. A lovely cabinet piece that speaks to the geologic diversity of the American West.
