Bi-colored Fluorite (old - fluorescent) Trimingham Coll.

Item Description

Transparent to translucent bi-colored cubes, to 1.5 cm, cover the mounded fluorite matrix on this rich and showy small cabinet specimen. The cubes have typical for the locale transparent gray corners with hints of pretty light lavender around veiled white centers. Fluorite specimens of this richness and quality are uncommon from this well-known, old Alston Moor mine, intermittently active from 1770 until the early 1900s. Choice, nearly pristine material, with only one small edge bruise noted in the interior. BRIGHT blue-white fluorescence. Ex Bob Trimingham Collection and purchased in 1960. This fine piece is undoubtedly from the Smallcleugh Mine, not the Coal Cleugh Mine named on Bob's label. Valued by the former dealer at $500.
