Atlantisite Polished Specimen — Serpentine & Stichtite, Green & Violet, 8g — Field Find

THE FIND
A polished atlantisite specimen, 8g — deep green serpentine with violet and pinkish-purple stichtite blooms moving through it like something painted beneath the surface. At only 8 grams, a tiny specimen with an unusually strong visual identity. Green earth. Violet bloom. One small stone holding both.

WHAT WE KNOW
“Atlantisite” is a trade name used for a rock composed of green serpentine with purple stichtite inclusions. Serpentine refers to a group of minerals (lizardite, antigorite, chrysotile) that typically form through the metamorphic alteration of ultramafic rocks. Stichtite is a magnesium chromium carbonate mineral (Mg₆Cr₂CO₃(OH)₁₆·4H₂O) that occurs as purple to pink material associated with serpentinite. The combination produces the characteristic green-and-violet patterning. “Atlantisite” is not a formal mineral species name — it is a trade name for this specific mineral pairing, most commonly sourced from Tasmania, Australia. This specimen weighs 8g. Locality not independently verified.

THE STORY
Stichtite is a relatively uncommon mineral — chromium-bearing carbonate minerals are rare in general, and the specific conditions that produce stichtite within a serpentinite host are more specific still. The Stichtite Hill locality in Tasmania remains one of the most productive sources for the serpentine-stichtite combination that the trade calls atlantisite. The polishing process is what makes the pairing visually legible: the contrast between the green serpentine matrix and the violet stichtite blooms is maximized by the smooth surface.

WHY WE CHOSE IT
The color contrast on this piece is strong for 8g — the violet stichtite is clearly visible against the green serpentine ground. A compact specimen with a visual identity that competes with much larger pieces. Appealing to collectors who value unusual mineral pairings and the story behind a trade name.
