Metamorphic Minerals
Seraphinite
Seraphinite is a trade name for clinochlore, a soft green mica-group mineral whose feathery, silver-flashing sheen (which gave it its angel-wing marketing name) comes from a single documented source deep in Siberia, making genuine material effectively single-locality material rather than a widely distributed mineral.
The geology — what Seraphinite actually is
- Mineral class
- Silicate (chlorite group, clinochlore species)
- Chemical formula
- (Mg,Fe)5Al(Si3Al)O10(OH)8
- Crystal system
- Monoclinic
- Mohs hardness
- 2–2.5
What causes the color: The deep forest-green bodycolor comes from iron and magnesium in the layered phyllosilicate structure, while the distinctive silvery, feather-like flash comes from fine fibrous inclusions of a related chlorite mineral aligned in wavy bands within the rock.
How it forms: Forms through low-to-medium-grade metamorphism of iron-and-magnesium-rich rock, developing its characteristic feathery texture as fibrous chlorite crystallized in curved, wave-like layers within the host stone.
- Lake Baikal region, Russia (the Korshunovskoye deposit is the primary commercial source of gem-quality material)
Treatments & imitations: Typically sold as polished cabochons or slabs with no chemical treatment; because it comes from essentially one region, genuine seraphinite is fairly consistent in appearance, making crude dyed-rock imitations easier to spot by their lack of the fine feathery texture.
Real vs. fake: Genuine seraphinite shows a fine, feather-like silvery pattern within a rich green base under good light — a texture that comes from real fibrous mineral inclusions and is difficult to fake convincingly with dye or resin, which tend to look flat by comparison.

- Seraphinite cabochon pendant
The feathery silver pattern is fine fibrous chlorite, and at Mohs 2 to 2.5 it marks against almost anything. This page recommends a pendant over a ring for that reason, and gentle wiping over any wet cleaning.
The tradition — how people use Seraphinite
Historical use: Seraphinite has no ancient documented history — its commercial name and popularity as a collector and jewelry stone are a late-20th-century development tied to the opening of its single known Siberian source to Western mineral dealers.
Metaphysical tradition: Modern crystal-healing tradition draws directly on the marketing name itself, associating seraphinite with angelic or heart-centered themes — an association that's explicitly rooted in the trade name (from 'seraphim') rather than any inherited practice.
How to use it: Most often cut as cabochons, beads, or polished slabs to display the feathery pattern; because of its softness, it's more commonly set in pendants than rings, where it's less exposed to daily impact.
Cleansing & care: At Mohs 2–2.5, seraphinite is soft and easily scratched — store it away from harder stones, avoid water soaking for extended periods, and clean only by gentle wiping rather than any abrasive method.
Frequently asked questions
If seraphinite comes from only one deposit, why isn't it rarer and more expensive?
The Korshunovskoye deposit produces the mineral in genuinely substantial quantity even though it's the only significant commercial source — single-locality doesn't automatically mean scarce, since some single-deposit minerals (this one included) simply happen to occur abundantly at that one site, unlike genuinely limited single-locality material such as larimar or tanzanite, where the deposit itself is both singular and comparatively small.

Green Calcite
Calcite Group
Calcite is one of the most common minerals on Earth — it's the primary component of limestone and marble, meaning humanity has quarried and carved calcite in some form for as long as it's built in stone — and its softness (Mohs 3) is so definitional to the mineral hardness scale that calcite itself is literally the reference point for hardness level 3. Green calcite specifically gets its color from trace metallic impurities, a much more delicate and fragile material than its extensive use in architecture might suggest.
Fuchsite
Mica Group Minerals
Fuchsite is a bright green, chromium-rich variety of the mica mineral muscovite, named after 19th-century German mineralogist Johann Nepomuk von Fuchs — it's the same mineral responsible for green aventurine's sparkle, discussed on that stone's own page, since fuchsite is frequently found as glittery inclusions within quartz rather than as pure sheets on its own.
Unakite
Altered Granite (Rock)
Unakite isn't a mineral at all — it's a rock, specifically granite that's been partially altered so that its original dark, mafic minerals have been replaced by green epidote while surviving patches of pink potassium feldspar remain untouched, producing the mottled pink-and-green speckled look the stone is known for. It's named for the Unaka Range in the Blue Ridge Mountains of Virginia and Tennessee, where it was first formally described in the 19th century.
