Fire Agate: Also see Agate. This stone shows a glowing iron-induced optical effect covered by brownish agate. Leaving only a very thin layer of Agate above the inclusions is crucial but once the iron inclusion surfaces too much the stone looses its fire. This Chalcedony (Agate) is found in Mexico where it occurs in Agate geodes and fist size bulbous aggregates.

Fluorite:  Fluorite (also called Fluorspar) is a mineral composed of Calcium and Fluoride. It grows in  very symetrical crystals with a cubic habit and is famous for its colourvariety. As a gemstone used in jewelry it is beautiful in facetation and polished but very sensitive to pressure due to the low hardness. It exists almost worldwide and Fluorite is mainly mined as a source to produce Fluor.

Fossil Coral:  Fossils are mineralized or otherwise preserved remains or traces (such as footprints) of animals, plants, and other organisms. Fossilization is an exceptionally rare occurrence, because most components of formerly living beings tend to decompose quickly following death. In order for an organism to be fossilized, the remains normally need to be covered by sediment (or other materials like treesap) as soon as possible. Mineralconcentrations occuring during the fossilization define the consistency, hardness and the different colours of fossilfindings. In our jewelry we utilize petrified tree sap, ammonite, coral, trilobite, shark teeth, seashells, snails, sand dollars (sea urchin), wild horses fossil teeth, dinosaur bone and various fossilized woods.

Freshwater Pearl: Pearls mainly consist of Aragonite, which is formed by a shell around an intruding particle. With cultured freshwater mussels the growth of the pearl is triggered by a little cut in the epithelcells on the inside of the shell. Lacking a nucleus, those freshwater pearls are often not perfectly rounded, but are said to be more resistant against pressure, acid or sunlight-induced fading in colour. It is also easier with Freshwater pearls to culture freeform or odd shaped objects by specific manipulation of the epithel cut. Those different shaped or half round pearls are generally called Mabe-or Blisterpearls.
