Calcite on Dolomite (classic material)

Item Description

A wonderful big cabinet sized display specimen of these unique "hedgehog" or "pineapple"-like, spiky spherical aggregates of soft yellow colored Calcite crystals from the famous Boldut Mine in Romania. The Calcite groups measure up to about 3.7 cm across, and are very attractively perched on the lustrous, tan Dolomite covering Pyrite and Quartz matrix. Very aesthetic and showy combination material from this classic locale. This unusual Calcite style is a signature of the locality, and you rarely seen specimens of this size and quality on the market anymore. Very little damage and quite showy! Valued $3,500.
From the collection of Jack Halpern No. 2757. 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.
