NZL87AP3: A pair of interpenetrant Fluorite crystals of an exceptional size for the deposit, with a very deep and uniform purple-blue color, being of a darker tone, more intense on the edges (best seen in the backlit photo). The crystals have perfectly sharp cube faces with polycrystalline growths on the crystal faces and also on one of the edges, which may seem broken but, in reality, it is recrystallized with polycrystalline growths. Coming from the well-known Asturian mine of La Viesca, specifically from one of the best vugs ever found there: the Las Monjas vug, discovered in May 2010
