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.

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.

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.
