Fluorite rough for craft & carving

Fluorite Rough Stone for Craft & Carving

Our natural fluorite carving‑grade rough stone is specially selected for decorative artwork, spheres, ornaments and mineral specimens.

Different from industrial‑grade fluorspar, CaF₂ purity is not the primary indicator.

Physical quality including rich colour banding, good translucency and minimal open cracks is our core selection standard. ‑ CaF₂: 85‑92% min ‑ SiO₂: ≤6.0% ‑ Fe₂O₃: ≤0.4% ‑ Moisture: ＜3% ‑ Lump size: 3‑20 kg per block ‑ Feature: massive dense structure, purple‑green rainbow banded, few natural fine veins, no penetrating cracks.

Each piece is one‑of‑a‑kind natural mineral. We can sort materials according to your requirements on colour, transparency and block size.

Key indicators for Jade‑grade / Carving‑grade Material and Gem‑quality Single‑crystal Specimen Material

1. Jade‑grade / Carving‑grade Material (for ornaments, fluorite spheres, stone‑carving art, massive aggregate)

Transparency: Translucent to sub‑translucent Colour: Purple, green, blue, yellow and multicoloured banding (purple‑green banding is the most popular); bright and even colour tone Cracks: No penetrating large cracks. Fine natural veils are acceptable. The stone shall not crack or spall during processing. Texture: Dense massive structure, free of loose material and honeycomb voids.

2. Gem‑quality Single‑crystal Specimen Material (cubic crystals, mineral‑collection purpose)

Crystal form: Well‑defined cubic shape with sharp crystal edges Transparency: Transparent to highly transparent Clarity: Few veils and fractures, no dark spots Fluorescence effect (bonus feature): Blue / purple / green fluorescence visible under ultraviolet light Hardness: Mohs hardness 4 (inherent property of fluorite)
