Lapis Lazuli Sphere — Deep Blue with Calcite Core + Pyrite Inclusions

Lapis Lazuli Sphere — Deep Blue with Calcite Core + Pyrite Inclusions

A rich lapis lazuli sphere showing deep ultramarine blue with scattered metallic pyrite inclusions and a distinct central calcite-rich core.

This piece is a great visual example of how lapis forms as a metamorphic rock, combining multiple minerals into one structure — rather than being a single crystal.

The contrast between the intense blue lazurite, pale calcite core, and gold-toned pyrite creates a natural “planet-like” effect when viewed from different angles.

🔍 Key Features

📍 Deep royal blue lazurite-rich body

📍 Central calcite core zone (light grey/white)

📍 Scattered pyrite inclusions (metallic gold flecks)

📍 Natural banding and mineral transitions

📍 High polish enhancing colour contrast

📍 Strong visual “orb/core” formation

📏 Dimensions

Diameter: 3 cm

Weight: 40 grams

🧪 Geological & Scientific Notes

Rock Type: Lapis Lazuli (metamorphic rock)

Primary Mineral: Lazurite

Other Components: Calcite, Pyrite

Chemical Composition (Lazurite): (Na,Ca)₈(AlSiO₄)₆(SO₄,S,Cl)₂

Mohs Hardness: 5 – 5.5

Lustre: Dull to vitreous (pyrite = metallic)

Transparency: Opaque

Lapis lazuli forms through metamorphism of limestone, where heat and pressure transform the original rock and allow new minerals to develop.

The blue colour comes from lazurite

The white/grey areas are calcite remnants

The gold flecks are pyrite (iron sulphide)

This mix is what makes every piece completely unique.

🧼 Care

Softer than quartz — handle with care

Avoid water soaking (can affect calcite)

Clean with dry or slightly damp cloth

Keep away from acids and chemicals

💡 Why This Piece Stands Out

✔ Clear core formation — very eye-catching

✔ Strong contrast between blue, white, and gold

✔ Balanced mineral distribution (great display piece)

✔ Compact size but high visual impact

This is the kind of piece that naturally draws attention on a shelf.
