However, the name did not become widely established until the 18th century, resulting in many old synonyms over the centuries such as cathedonian, pseudoquartzine, Swallowstone, Beekite, Sapphirite, Zoesite, Jasponyx, Quartzite, Jenzschite, Calcedony, Lutecine, Massic, Staarstone, Milkystone, Rednerstone, and Myrickite. Trade names include blue Moonstone and California Moonstone.

Occurrences, main supplying countries of chalcedony

The most important finding places of the blue chalcedony are in Brazil, India, Namibia, Turkey, South Africa, Mozambique as well as Russia.

Most of the commercial blue chalcedony came from Namibia. However, this deposit is now finally exhausted, as the several hundred meters high cap rock above the deposit would have to be removed and this is currently not economical economical. All articles made of this stone from this deposit are therefore stock items that can no longer be procured. However, through worldwide relationships, we have been able to secure corresponding raw materials in limited quantities and will gradually be able to offer you appropriate products from it. The blue chalcedony now available on the market is mainly from Turkey and Malawi, but it does not show the well-known banding and the chalcedony layers are much thinner. Therefore, at the moment only small Stone parts are cut from it such as Tumbled Stone or small pendants.

The Colors of chalcedony

The blue chalcedony from South Africa is a very interesting and rare material. Although chalcedony in itself is quite common, the blue stone is found in only a few locations. The color is usually a clear, pure sky blue, often with streaks. The color is caused by tiny enclosed fibers from other minerals. These scatter the light in a very special way, so that only the blue light is reflected out of the stone, while other colors (especially the red part) are absorbed. This special feature of the blue chalcedony was discovered by the Irish physicist John Tyndall. In his honor, this behavior is called "Tyndall effect". So the color is not caused by foreign substances as so often with other minerals, but only by the light refraction effect at finest lamellae.

Their microcrystalline, fibrous, radial-rayed structure is typical. Chalcedony is formed primarily or secondarily from aqueous silica solutions at temperatures below 100°C. It is found as gangue, fissure or cavity fillings in sediments, magmatites and metamorphic rocks. If the solution is in motion during hardening, it shows a typical it shows a typical banding, while at rest it is uniformly transparent. Chalcedony Rosettes can form at hot springs, which may resemble flowers, plants or organs.
