Phlogopite on Marble (both fluorescent) Hefendehl Coll.

Item Description

A fantastic 4.7 cm cluster of four tectonically offset, en echelon segments of a large phlogopite crystal are dramatically set on the large granular marble matrix. The highly lustrous, glassy, sharp textbook hexagonal segments are a translucent golden-brown to brown under normal light. However, the segments GLOW with golden-yellow gemminess, when backlit! Mustard-yellow phlogopite and modest pink marble SW UV fluorescence. Sections of red LW UV fluorescent purple Spinel crystals, to 1.8 cm, on the edge are a fine accessory and color contrast. Ex Hefendehl Collection. Kurt Hefendehl was a most well-known collector in the mineral world all over Europe with worldwide contacts to dealers and collectors. He started seriously collecting in the age of 14 and his great and various worldwide collection reached a number of over 6000 pieces. He was incredibly mineralogically active, until shortly before his passing in 2020 in the age of 82 years. His collection had, considering that high number of pieces, an unusual high quality standard from most worldwide localities. He particularly specialized in all classics; and the minerals of the Black Forest where he spent many visits collecting (that and the Germany subcollection went to his good friend Wolfgang Wendel. The Italian suite went to Marini). We have the rest to offer over the next 2-3 years, through our platforms. We have lost a great friend and connoisseur, a true mineral collector of the Golden Age. These gemmy golden phlogopite are certainly among the world's finest examples of the species. An amazingly artistic combination from the well-known Koksha Valley locale.
