Item Description

The classic combination of Aragonite with Sulfur from Sicily is one of the most well-known European combos out there. This particular specimen is a very fine example of this well-known material especially from the standpoint of the Aragonites. Several very fine quality, sharp, highly lustrous, very well-formed, colorless to white pseudo-hexagonal cyclic twins of Aragonite measuring up to 3.5 cm across are associated with a layer of brilliant yellow Sulfur on the reverse side. The superb vitreous / resinous luster of the Aragonites combined with the fact that they are partially gemmy in areas makes them really good quality for the species. Overall, there are a few imperfections, but the piece is in very good condition and really looks better in person. If you've ever wanted a piece of this classic material, don't miss out on this one because it's good for what it is. A lot of the Aragonites from Agrigento can be dull and slightly etched, but these crystals are glassy, smooth and really eye-catching. The piece also shows a fantastic pink fluorescence under UV light. From the worldwide collection of David Burgess (1951-2016). David was a prolific species collector from Newington, Connecticut, and the namesake for the extremely rare cobalt arsenate species Burgessite, which he discovered. The piece is accompanied by a hand-written label from Russ Behnke with a retail price of $350, but easily worth more today.
