Forsterite var: Peridot

Item Description

Some of the best crystallized specimen of Peridot today are those from Sapat Gali in Pakistan. Typically Peridot is found as loose single crystals in other world localities, or more typically as broken sections of crystal which are really only suitable for cutting gems. The piece Sapat Gali are certainly in the higher echelon in terms of size, color, sharpness and transparency for actual crystals in the modern era of collecting. These attractive Peridots crystals began showing up in the early 1990s and no world locality has produced the quality and quantity of euhedral Peridot crystals like Sapat Gali. This small sized piece is filled with many rich lime green colored, sharp, well-formed, euhedral, gemmy/translucent crystals, with minor attached matrix. The top portion of the crystals glow with color when backlit. It's rare to find such a dense multi-crystal group from this locality, most of the time you only see singles, or groups with a few crystals, but there are close to 20 crystals on this piece that I can see.
From the collection of Jack Halpern No. 2505. Jack was born May 18, 1920 in Brooklyn, New York, but has been a long-time resident of San Francisco. He assembled one of the great mineral collections in the world encompassing over 3,200 specimens with a specific emphasis on color, quality, and style/aesthetics, which is evident in every piece. He admired specimens of all sizes from thumbnails to large cabinets and the vast majority of them rank from fine to world-class in their quality.
Above all else, Jack is considered to be the greatest gentleman in the modern era of mineral collecting. He is beloved by all those who have met him, and he truly is one of the most iconic figures in the mineral world. We recently acquired Jack's collection, and the VAST majority of these pieces will be offered here in the auctions, as we feel that everyone deserves and equal opportunity at acquiring these important, well-documented and fine quality pieces for their collections. We are honored to have the opportunity to offer Jack's treasures to everyone on a regular basis in the auctions.
