Chalcedony Malawi
Chalcedony is, in fact, a cryptocrystalline variety of quartz. Depending on the type of admixtures in chalcedony, we distinguish individual varieties of this stone. The most popular ones are agate, carnelian, onyx, heliotrope and jasper. This unique, blue piece is from a site near the village Ngabu, Malawi. This chalcedony comes in pleasant blue shade. The stone usually creates cavities and veins up to several centimetres thick, accompanied by quartz and calcite growing into the chalcedony vein.
Special conditions/ treatment: Chalcedony is itself a firm and stable stone. Please, do not use chemical detergents to clean the chalcedony varieties with small calcite veins.
To process our rough stones we use special technology, which gives each stone an unusual decorative look. To retain the standard colour and quality of the minerals, we carefully pick the best pieces and thoroughly clean them. We process only the best quality raw material, stones with non-standard colour or surface imperfections are removed.
About the product: We sell rough minerals in one-kilogram packages, but we also offer discounted value packages of 5 kg and 25 kg in a cardboard box. XXL-JUMBO sized stones are available only in the value packages of 5 kg and 25 kg..
