Fluorite Tower — Banded Growth with Zoned Colour Formation

Fluorite Tower — Banded Growth with Zoned Colour Formation

A cleanly polished fluorite point showing classic colour zoning and banded crystal growth, formed through changes in trace elements during crystallisation.

Fluorite is well known for its ability to grow in distinct layers, which can appear as bands, colour shifts, or internal zoning — all of which are visible in this piece.

🔍 Key Features

📍 Visible colour zoning / banding (growth stages)

📍 Smooth polished tower enhancing internal structure

📍 Natural variation in tone from trace elements

📍 Clean edges with well-balanced shape

📍 Subtle internal translucency

📏 Dimensions

Weight: 73 grams

Size: 8.7 cm x 2.3 cm

🧪 Geological & Scientific Notes

Mineral: Fluorite

Chemical Formula: CaF₂

Crystal System: Cubic (isometric)

Mohs Hardness: 4

Lustre: Vitreous

Transparency: Transparent to translucent

Why the colours change:

Fluorite’s colour comes from:

Trace elements (like yttrium or rare earth elements)

Natural radiation exposure altering electron structure

Growth interruptions creating zoned layers

This is why fluorite often shows: 👉 Bands

👉 Colour shifts

👉 Internal “sections” rather than uniform colour

Each layer represents a different stage of crystal growth conditions.

🧼 Care

Softer mineral (Mohs 4) → scratches easily

Avoid knocks and drops

Keep away from harder crystals (like quartz)

Do not leave in prolonged strong sunlight (can fade colour)

Clean gently with a soft cloth

💡 Why This Piece Stands Out

✔ Tall, slender tower = strong display presence

✔ Clear visible growth zoning (educational + visual appeal)

✔ Polished finish enhances internal structure

✔ Ideal “entry + collector crossover” piece

Fluorite towers like this sell well because they balance: 👉 aesthetics

👉 affordability

👉 visible science
