Pectolite (ex Kay Robertson Collection)

Item Description

In addition to the some of the world's best Garnets, the Jeffrey Mine in Canada can lay claim to some of the finest Pectolite crystals found. These well-formed clusters of bladed to tabular Pectolite crystals have excellent luster, good gemminess, and are a soft shade of green. The largest group measures 1.0 cm, which is fairly decent for the species and the locality. The matrix has moderate fluorescence, though I am not quite sure exactly what its composition is. This piece likely dates to the 1970s or early 1980s. A fine specimen for this famous mine. Ex Kay Robertson Collection (#8450). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).
