Physical properties

Formation & geological history

Formed as an alteration product of magnesium-rich minerals like pyroxene, biotite, and amphibole. It is a specific gem-grade variety of clinochlore formed in metamorphic environments, primarily in the Pre-Cambrian Korsthunovskoye deposit.

Uses & applications

Primarily used as a decorative stone, in jewelry (cabochons, pendants), and for metaphysical or collection purposes. It is too soft for rings but popular for earrings and necklaces.

Geological facts

Its name is derived from the 'Seraphim' (the highest order of angels) because the feathery silver mica inclusions resemble wings. It is almost exclusively found in the Lake Baikal region of Siberia.

Field identification & locations

Identify by its unique 'feathery' silver chatoyancy (shimmer) against a forest green background. It is relatively soft and can be scratched with a copper coin. Look for the distinct radial patterns of chlorite fibers.
