Sulfur on Aragonite from Falconera Section, Cianciana Mine, Argrigento Prov., Sicily, Italy [db_pics/pics/K942a.jpg] Sulfur on Aragonite from Falconera Section, Cianciana Mine, Argrigento Prov., Sicily, Italy [db_pics/pics/K942b.jpg] Sulfur on Aragonite from Falconera Section, Cianciana Mine, Argrigento Prov., Sicily, Italy [db_pics/pics/K942c.jpg] Sulfur on Aragonite from Falconera Section, Cianciana Mine, Argrigento Prov., Sicily, Italy [db_pics/pics/K942d.jpg]

Isolated, gemmy single Sulfur crystals suspended in light, airy Aragonite. The specimen formed as a floater in the center of a pocket and is different in style than the usual crystals on solid Aragonite that are collected from pocket walls. This was the most aesthetic example (in my opinion) from the find. Crystals reach 1.3cm in diameter and are present on both sides.

Complete 'citrus' orange Spessartine crystal from old finds in Tanzania. These were mostly found as partial or damaged crystals with perfect complete crystals such as this much less common. Equant form with very minimal edge wear, otherwise no damage. There are a few small areas of black Braunite inclusions, otherwise it's nothing but gemmy orange. These were often cut up into spectacular gemstones, and this one could cut a number of small gems.

Quartz var. Polyhedral Agate from Paraiba, Brazil [db_pics/pics/K936a.jpg] Quartz var. Polyhedral Agate from Paraiba, Brazil [db_pics/pics/K936b.jpg] Quartz var. Polyhedral Agate from Paraiba, Brazil [db_pics/pics/K936c.jpg] Quartz var. Polyhedral Agate from Paraiba, Brazil [db_pics/pics/K936d.jpg] Quartz var. Polyhedral Agate from Paraiba, Brazil [db_pics/pics/K936e.jpg]

Rare polyhedral Agate from Brazil, famous for the their angular geometric shapes rather than the more typical agate form of rounded nodules. How these formed is still debated but the general consensus is that they are the result of agate forming in the space between preexisting crystals of other minerals such as gypsum, barite, or anhydrite. These were found in the 1970s and the locality that used to produce them is now under water due to the construction of a dam. This is a good large example in excellent condition.
