Fluorite

Such a banger Larkin Quarry fluorite
Larkin’s Quarry in Shannapheasteen, Co. Galway, Ireland, is a notable, modern locality known for producing high-quality, deep purple to violet-blue fluorite crystals found around 2015–2020. These, often cubic, crystals are typically found in granite matrix, featuring sharp, lustrous, and sometimes “phantom” zoned, gemmy, and, occasionally, fluorescent properties.
