Atlantisite belongs to the natural mineral family of serpentine group minerals, specifically a cryptocrystalline intergrowth of stichtite within a serpentine matrix. Its formation occurs in low‑temperature hydrothermal veins and metamorphosed limestone, where magnesium‑rich fluids precipitate fine‑grained carbonate‑phosphate phases. The stone’s amorphous‑to‑cryptocrystalline texture gives it a silky, opalescent appearance that distinguishes it from crystalline serpentine varieties.
What is Atlantisite (stichtite In Serpentine) Gemstone? Geological Overview & Definition
Atlantisite is defined as a cryptocrystalline aggregate of stichtite crystals embedded in a serpentine host, resulting from metasomatic alteration of ultramafic rocks. The intergrowth creates a semi‑transparent to opaque gemstone whose color is governed by trace chromium and nickel ions substituting into the lattice.
In the field, Atlantisite is found as nodular masses or laminar sheets within serpentinite bodies, often associated with talc, chrysotile, and magnesite. Its formation requires a delicate balance of pH and temperature, typically 150–250 °C, allowing carbonate‑phosphate layers to nucleate within the serpentine sheets.
Atlantisite (stichtite In Serpentine) Gemstone Chemical Composition & Crystallographic Properties
The mineral is amorphous to cryptocrystalline, lacking long‑range order, which distinguishes it from well‑defined serpentine polymorphs. Its bulk composition approximates (Mg,Al)_6(CO_3)(OH)_16·4H_2O, with carbonate groups occupying interlayer sites and hydroxyls completing the hydrogen‑bond network.
Cation substitution is extensive: Al³⁺ can be replaced by Fe³⁺, Cr³⁺, or Ni²⁺, creating localized color centers that produce the characteristic blue‑green hues. These substitutions also affect density, raising the specific gravity to 2.6–2.8 compared with pure serpentine.
Atlantisite is acid‑sensitive; dilute hydrochloric acid will effervesce weakly, dissolving the carbonate component while leaving the serpentine framework largely intact. This reaction is a diagnostic test distinguishing it from pure serpentine, which is generally acid‑resistant.
Thermally, Atlantisite dehydrates above 200 °C, losing structural water and gradually converting to a more crystalline serpentine phase. Prolonged heating can cause color fading as chromophore ions migrate, underscoring the need for careful handling in jewelry settings.

Atlantisite (stichtite In Serpentine) Gemstone Varieties & Color Spectrum
Atlantisite is a commercial trade name for stichtite hydroxide minerals found within serpentine host rocks. It is not a distinct mineral species but a specific variety of hydromagnesite or related layered double hydroxides. The gemstone market primarily recognizes it for its distinctive greenish-blue to grayish-green hues. These colors result from trace impurities and the specific crystal lattice structure of the host matrix.
Classic Green Atlantisite
This variety exhibits a deep, forest-green coloration derived from iron oxide inclusions. It typically forms in serpentine deposits where hydrothermal fluids have altered ultramafic rocks. The stone often displays a waxy luster and may contain visible stichtite crystal plates. High-grade specimens are prized for their uniform color and lack of large fractures.
Blue-Grey Atlantisite
Characterized by a muted, steel-blue tone, this morph is rarer than its green counterparts. The blue tint arises from specific manganese substitutions within the hydroxide lattice structure. These stones often appear in matrix form, showcasing the contrast between the mineral and the host rock. Collectors value this variety for its unique, subdued aesthetic appeal.
Matrix Atlantisite
This trade variety features stichtite crystals embedded directly in a serpentine matrix. The host rock provides a contrasting background that highlights the gemstone’s color. Inclusions of chlorite and other secondary minerals are common in these specimens. It is the most commercially available form, often cut into cabochons or tumbled stones.
Pale Green Atlantisite
A lighter, almost mint-green variant, this type indicates lower iron content in the formation zone. It often forms in the upper layers of serpentinite bodies where oxidation is more prevalent. The stone may exhibit a slight translucency when cut thin. Its delicate appearance makes it popular for intricate jewelry designs.
Dark Olive Atlantisite
This variety presents a dark, olive-green hue with a dense, opaque appearance. It is associated with high-pressure metamorphic conditions during the serpentinization process. The stone frequently contains fine-grained magnetite inclusions that contribute to its darkness. It is less common in the high-end gem market but valued by mineral collectors.
Where is Atlantisite (stichtite In Serpentine) Gemstone Found? Geological Mining & Extraction
Atlantisite primarily occurs in serpentinite bodies, which are formed by the hydration of ultramafic rocks.

Safety & Mineral Profile of Atlantisite (stichtite In Serpentine)
Safe handling and physical stability
Atlantisite, a stichtite‑in‑serpentine composite, is a relatively soft mineral with a Mohs hardness of 2–3. Its fibrous serpentine matrix can become friable when exposed to prolonged light or mechanical stress, and the embedded stichtite crystals may release fine dust that can irritate the respiratory tract. The material does not contain significant concentrations of heavy metals such as lead or cadmium, but it can contain trace amounts of sulfur and iron that may oxidize when exposed to moisture, producing a mild acidic reaction on contact with skin. Because of its softness, tendency to fragment, and potential for dust inhalation, atlantesite is best displayed as a collector specimen rather than fashioned into jewelry. Proper handling requires gloves, eye protection, and a well‑ventilated workspace, and specimens should be stored in a dry, cool environment to prevent degradation.
Scientific and educational significance
In museum collections atlantesite serves as an excellent example of mineral‑in‑mineral relationships, illustrating the incorporation of stichtite within a serpentine host. Its distinctive fibrous texture and color contrast provide a visual aid for teaching concepts such as mineral alteration, host‑matrix interactions, and the formation of secondary minerals in hydrothermal veins. Researchers use atlantesite to study the geochemical pathways that lead to stichtite precipitation, offering insights into low‑temperature hydrothermal processes and the role of organic matter in mineralization. The specimen’s accessibility and diagnostic features make it a valuable educational tool for both undergraduate geology courses and advanced mineralogical research.
Mineralogical Group and Planetary Lore of Atlantisite (stichtite In Serpentine)
Atlantisite derives its name from the ancient mythological city of Atlantis, reflecting early 19th‑century mineralogists’ fascination with exotic locales. Historically, the mineral was first described in the serpentine‑rich deposits of the Kola Peninsula in Russia, where it was noted for its striking greenish‑blue hue and fibrous appearance. According to early mineralogists, atlantesite was classified within the serpentine group due to its dominant host mineral, yet the presence of stichtite crystals warranted a separate subcategory. In lapidary texts, atlantesite has occasionally been linked to planetary symbolism, with some writers speculating a connection to the “blue planet” because of its color, though such associations remain speculative and are not supported by modern geological evidence.
How to Identify Real vs. Fake Atlantisite (stichtable In Serpentine) Gemstone
Artificial imitations of Atlantisite often include dyed serpentine, colored glass, or resin composites that mimic its pale green hue. Synthetic glass pieces may display a uniform clarity that lacks the natural veining characteristic of genuine material. Dyed replicas can be identified by overly bright coloration and a lack of the subtle translucency found in authentic stones.
Practical At-Home Authenticity Tests
- Temperature Test (Thermal Feel): Hold the stone; genuine Atlantisite feels cool to the touch and retains that coolness longer than glass or plastic, which quickly warm to skin temperature.
- Specific Gravity & Weight Test: Atlantisite is relatively heavy for its size (specific gravity ~2.6). Compare its heft to a known serpentine sample; a noticeably lighter piece may be a glass imitation.
- Scratch & Hardness Test (Mohs Comparison): With a steel nail (hardness ~5.5), a real Atlantisite (Mohs 5–6) will resist scratching, whereas glass (hardness ~5.5) may show a faint mark; a softer polymer will scratch easily.
- Microscopic & Loupe Inspection (Internal Inclusions): Examine under 10× magnification; authentic Atlantisite displays fine, irregular inclusions and natural veining, while synthetic glass appears uniformly clear with no internal features.
