Helvine with Spessartine, smoky Quartz and Feldspar.
MB53F1: Helvine with Spessartine, smoky Quartz and Feldspar
Helvine is not well known and is rarely found in this locality, which has become very famous for its Spessartine. The crystals of Helvine in this specimen are really large, have octahedral faces, and well-defined edges. The smoky Quartz base supports the crystals of Spessartine and prisms of Feldspar, possibly Orthoclase. When combined with the Helvine this makes it one of the best for the species, and certainly for this locality. This specimen was photographed for the whats new at Munich 2004 section of the magazine Mineralien Welt and appears on page 7 of number 1/2005. We will send the purchaser a copy of the magazine.
