Serpentine (Specifically 'Atlantisite' variety)
Stichtite in Serpentine (var. Atlantisite) · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Monoclinic (Serpentine) and Trigonal (Stichtite); usually occurs in massive, microcrystalline form.
Mineral Group
Silicates (Phyllosilicates) and Carbonates
Chemical Formula
Mg3Si2O5(OH)4 [Serpentine] mixed with Mg6Cr2CO3(OH)16·4H2O [Stichtite]
Formation Process
Metamorphic; specifically the hydrothermal alteration of ultramafic rocks (peridotite) into serpentinite, containing chromium-bearing minerals.
About This Crystal
An opaque, chartreuse-to-lime green matrix of serpentine featuring splotches, veins, or inclusions of dark purple-to-brownish stichtite. Luster is typically waxy to greasy.
Physical Characteristics
Color: Lime green with purple/dark inclusions; Streak: White; Cleavage: Poor/None in massive form; Fracture: Conchoidal to splintery; Specific Gravity: 2.44 - 2.62.
Optical Properties
Opaque; Refractive index approximately 1.56; No pleochroism or dispersion visible due to opacity.
Hardness & Durability
Origin Region
Primarily Tasmania, Australia (Stichtite Hill). Also found in South Africa and Canada.
Hardness & Durability
Mohs hardness 2.5 to 4. Very soft and brittle; susceptible to scratching and impact damage. Not recommended for rings.
Care & Maintenance
Avoid ultrasonic and steam cleaners. Clean only with warm soapy water and a soft cloth. Store separately to avoid scratching by harder stones like quartz.
Rarity & Value
Relatively uncommon; value is driven by the contrast between the green and purple colors. Generally affordable as tumbled stones or cabochons.
Special Characteristics
Known for its unique two-tone aesthetic; some specimens may show minor greasy fluorescence under UV light depending on magnesium content.
Lore & History
Commonly called 'Atlantisite' in New Age circles; historically, serpentine was used by Romans as protection against witchcraft. It is traditionally associated with the Heart and Crown chakras.
