Seraphinite
Seraphinite
Dark green clinochlore with silvery feathered chatoyant inclusions
Seraphinite is a trade name for dark green chatoyant clinochlore — a chlorite-group mineral — exhibiting silvery, feather-like fibrous inclusions that produce a shimmering, plumage-evoking optical character across the polished surface. The trade name derives from seraphim, the angelic figures of Judeo-Christian iconography, in reference to the wing-like inclusions. Seraphinite is sourced principally from the Korshunovskoye iron-ore district in the Lake Baikal region of eastern Siberia, Russia, where the material occurs as a by-product of iron-ore extraction. The mineral is too soft for conventional ring-wear jewellery and is encountered principally as cabochons, beads, and carved ornamental objects rather than in fine-jewellery production.
Mineralogy
Clinochlore is a hydrous magnesium-iron-aluminium silicate with the simplified formula (Mg,Fe)5Al(Si3Al)O10(OH)8, and is one of the principal members of the chlorite group of minerals. The variety known commercially as seraphinite is a dense, fine-grained aggregate of clinochlore exhibiting parallel-aligned fibrous inclusions that produce a chatoyant, silvery sheen on polished surfaces. The host clinochlore is a deep, slightly silvery green; the inclusions are silvery-white, micaceous in character, and oriented along structural planes within the host. Mohs hardness is 2 to 2.5, materially softer than nephrite jade, malachite, or any of the conventional cabochon-cut decorative materials.
Origin and supply
The principal commercial source is the Korshunovskoye iron-ore mine and surrounding workings in the Irkutsk Oblast of eastern Siberia, west of Lake Baikal. The mineral occurs as a contact-metamorphic by-product associated with skarn and iron-ore mineralisation, and is recovered alongside the principal iron-ore extraction rather than mined as a primary target. Supply is therefore tied to the operational status of the Russian iron-ore workings and is subject to interruption from broader trade and sanctions context affecting Russian commodity exports. Smaller occurrences elsewhere have been reported but the Siberian source dominates commercial production.
Working and finish
Seraphinite is cut and polished as cabochons, beads, slabs, and small carvings. The orientation of the inclusions relative to the cabochon dome is critical to optical effect — inclusions parallel to the polished surface produce the most visible feathered sheen, while inclusions oriented perpendicular show as faint streaks. Cutters orient rough deliberately to maximise surface chatoyancy on the principal viewing face. The hardness of 2 to 2.5 means the material polishes readily but scratches easily; care in finishing and in subsequent use is required.
Use in jewellery and ornament
Seraphinite cabochons are set principally in pendants and earrings — applications in which the stone is protected from abrasion and impact. Ring use is generally not advised; the hardness is below the practical threshold for daily-wear ring centres, and even occasional-wear rings risk surface damage from the casual contact of normal use. Beaded strands are common in the metaphysical and crystal-healing market, where seraphinite carries a substantial following independent of conventional gemstone retail. Carved ornamental objects and small figurines are produced from larger pieces of rough.
In the trade
Within the conventional fine-jewellery trade, seraphinite occupies a small niche limited by the material's softness. Pricing is modest at retail; rough trades by the kilogram at low to moderate prices, and finished cabochons trade at price points materially below jade, lapis, malachite, or other comparable decorative materials. The principal commercial channels for seraphinite are crystal and mineral-show retailers, the metaphysical market, and ornamental-object specialists rather than traditional fine-jewellery retail.
