Description: Demantoid Garnet, Ca3Fe2(SiO4)3, North ItalyA group green demantoid garnet crystals on a schist matrix. Demantoid is a variety of andradite, a calcium and iron rich garnet, characterized by a green color which makes it a popular gemstone. The green colour is probably the result of chromium substitution. It is the most expensive kind of garnet and one of the most precious of all gemstones. Particularly valuable, are the deep emerald green forms which are very rare, and display the spectacular brilliance and fire. Demantoid garnet was first found in the Ural Mountains of Russia in 1868, and quickly became popular with the Russian nobility, and was often used by the famous Russian jeweller, Carl Fabergé.

Description: Mesolimulus walchi, Jurassic, Eichstatt, Bavaria, GermanyA fine example of a horseshoe crab from the Jurassic, Solnhofen Limestone, a famous lagerstӓtten (a"fossil ore-body") renowned for its exceptionally preserved fossil fauna. The most famous fossil from this deposit is the primitive bird, Archeopteryx. In addition, beautifully preserved pterosaurs, insects, fish, starfish and numerous crustaceans have been found in this deposit.Horseshoe crabs are closely related to the extinct eurypterids (sea-scorpions), and more distantly to spiders and scorpions. This 150 million year old Mesolimulus specimen is almost identical to the modern day horseshoe crab Limulus (see picture right), found in shallow waters of South East Asia and North America.
