Carnelian: Also see Chalcedony. This red impure microcrystalline variety of Chalcedony is often found as a tumbled stone. The red colour is caused by iron. The oxidation of this iron can be triggered by fire, which was known also in earlier times and frequently used today to improve the red colour of this mineral.

Chalcedony: All microcrystalline (crypto-crystalline) fibrous forms of Silica (mainly Quartz) are called Chalcedony. Most famous colour for Chalcedony is bluish (Lavender Chalcedony). Many other coloured stones also belong to the mineral but are named individually: clear red chalcedony is known as Carnelian, the green variety colored by nickel is called Chrysoprase, Chalcedony with concentric banding is known as Agate. Flint is also a variety of Chalcedony as well as black Onyx.

Charoite: Only findings are known near the Siberian river Chara (hence the name). In Russia a long known gemstone with typical fibrous structures in dark violet colours (similar to Suggilite). Different dark inclusions are common and make the easily polishable stone more interesting in appearance. Because of its limited mining area (Charoite is not rare in that region) the mineral has become a valuable gemstone and increased in popularity over the past years.

Chrysocola: Normally this copper mineral is associated with Malachite, Azurite and Cuprite, it occurs in bright green or bluish, translucent with vitreous to greasy luster. It is found in Chile, USA, Africa, Italy, Russia and Morocco. We find our Chrysocolla mainly in the south American Andes.

Citrine: Lemon- to orangeyellow variation of Quartz (SiO2). Since the stones from natural sites are rare and the demand for Citrin increased steadily, is it probable that most of today’s Citrin on the market does not originate from natural sites. Heat or low irradiation causes some Quartzes (e.g. Amethyst) to turn to Citrin, which also occurred naturally under rare conditions (bushfire, volcanic activity). We use orangeyellow Brazilian Citrin and the so called Green Gold Citrin, which is not a genuine Citrin but a lemonyellow variety of Quartz mainly coming from Brazil and Africa.

Copper: Opaque with metallic luster in copper-red colour, often with a greenish film of Malachite.   Natural copper nuggets were always known as currency or trading items. Especially the Indian tribes along the west coast of Canada and the US used Copper nuggets as jewelry and decorative items for rituals. Naturally tumbled nuggets of copper can e.g. be found in the streams and rivers of Canada`s western regions. We use copper nuggets and cabochons mainly from the US and Canada.

Chalcedony Rose: Also see Drusy. A naturally grown Chalcedony rose (Concha) from the south of Brasil (Rio Grande do Sul) which we use with a slight metallic plating of Silica on the crystals.

Cyanite: Cyanite or Disthen forms long and deep intruding crystals of black or blue colour in Schiefer. It colour and hardness depends not on different ingredients but on the pressure and temperature during its metamorphic evolution. Along the crystals the mineral is rather soft and fibrous when broken. As the Cyanite is resistant to fire, acid and climate it was used in thin layers as window glass in former centuries. As a gemstone for jewelry Cyanite has only recently been discovered and can be used as rough handpicked crystals or polished gems in deep blue colours.
