Stichtite in Serpentine
Serpentine group with Stichtite · Decorative Stone and Semi-Precious Gemstone
Crystal System
Monoclinic (Serpentine) and Trigonal (Stichtite), typically found as massive or compact aggregates when tumbled
Mineral Group
Silicates (Phyllosilicates)
Chemical Formula
(Mg,Fe)_3Si_2O_5(OH)_4 with Mg_6Cr_2CO_3(OH)_16·4H_2O
Formation Process
Metamorphic alteration of ultramafic rocks such as peridotite and dunite, typically via serpentinization processes involving hydrothermal fluids rich in chromium and magnesium.
About This Crystal
This is a polished, tumbled pocket stone featuring a pale chartreuse to yellowish-green body color with distinct, dark green to nearly black dendritic or blotchy matrix inclusions. The surface is smooth and waxy with high polish.
Physical Characteristics
Color is yellowish-green with dark patches; white streak; no distinct cleavage; uneven to splintery fracture; specific gravity ranges from 2.5 to 2.6; tenacity is somewhat tough but compact; greasy to waxy luster.
Optical Properties
Biaxial negative for the serpentine components; translucent to opaque; no prominent chatoyancy or special optical phenomena, relying entirely on its contrasting color matrix for visual appeal.
Hardness & Durability
Origin Region
Stichtite in Serpentine (often marketed as Atlantis Stone or Tasmanian Jade) is famously sourced from western Tasmania, Australia, as well as South Africa and Canada.
Hardness & Durability
Mohs hardness is roughly 3.5 to 5, making it relatively soft and susceptible to scratching by harder minerals like quartz. It has fair durability for gentle jewelry use like pendants or earrings if protected.
Care & Maintenance
Clean with mild soapy water and a soft cloth. Avoid ultrasonic cleaners, steam cleaners, and harsh chemical detergents. Store separately from harder gemstones to prevent scratching.
Rarity & Value
Uncommon to rare depending on the specific color contrast and source locality (especially high-grade material from Tasmania). Typically valued moderately as a collector or decorative pocket stone.
Special Characteristics
Striking natural color contrast between the bright yellowish-green serpentine host rock and the darker or contrasting mineral inclusions.
Lore & History
Often associated with emotional healing, peace, and the heart and crown chakras in contemporary crystal lore. While popular in metaphysical circles, these properties are traditional beliefs rather than scientific claims.
