Dendritic opal is unique in the opal family; it is formed when water rich mineral solutions flows along naturally occurring fractures, fissures & bedding planes. In terms of a chemical structure, it is an amorphous silicon oxide with with high water content. Our dendritic opal comes from Brazil.

Stone uniqueness: Stones have mostly a milky white to brownish colour and they are opaque. Often they feature little black fern-like patches made by inclusions of iron, manganese, or other metallic oxides that create bold patterns within the mineral.

Special conditions/ treatment: Do not expose the stone to sunlight, it may lose its lustre. When exposed to very high temperatures, it may crack.

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 clean them.
