Natural Zircon and Spinel Rough

Discover the natural beauty of zircon and spinel rough gemstones, two distinctive mineral species appreciated by gemstone collectors, lapidaries and jewellery designers.

Zircon (ZrSiO₄) is a natural mineral known for its high refractive index, strong dispersion and attractive range of colours. Natural zircon crystals can occur in yellow, orange, brown, green, blue, red and colourless varieties. Its optical properties make suitable transparent rough material interesting for precision gemstone cutting.

Spinel (MgAl₂O₄) is another attractive natural gemstone, recognised for its brilliance, durability and wide colour range, including red, pink, purple, blue, orange and other shades. It has a Mohs hardness of approximately 8 and crystallises in the cubic crystal system.

Both zircon and spinel occur in alluvial gemstone deposits and may be recovered together in natural gem gravels. Their crystal shapes, colours, transparency and internal characteristics can vary considerably.

The suitability of each rough gemstone for faceting depends on its individual condition, including clarity, transparency, fractures, crystal size and potential cutting yield. Proper gemological identification is important because zircon and spinel have different chemical compositions and physical properties.
