The upcoming Rock, Gem, Mineral, and Fossils auction, presented by Lewis & Maese Auction Company, offers 300 lots of geological finds. Leading the collection is a large piece of amethyst shaped like a planet. The Greek legend associated with the stone tells that Dionysus, the god of intoxication and celebration, caused its purple color. Amethyst was believed to prevent drunkenness, overindulgence, and evil thoughts.
A piece of blue kyanite is also highlighted. German mineralogist Abraham Gottlob Werner first named this aluminum-rich mineral in a 1789 manual. The name comes from the Greek word kuanos or kyanos, meaning deep blue. Although kyanite is important from a geological perspective, it is rarely used as a gemstone due to its fibrous nature and easy breakage. Three septarian eggs are also available. During the Cretaceous Period over 50 million years ago, septarian was formed when volcanic eruptions encrusted mud, sea creatures, and other organic materials. When the ocean receded, these mud balls dried out and began to shrink and crack. This process yields the egg-shaped stones available in this sale.
