Corundum Specimens / Rough (Blue/Sapphire)

Blue Corundum / Sapphire Specimens

Small rough pieces of blue Corundum, a form of Aluminium Oxide, more commonly known as a 'sapphire'. These are not technically sapphire, as they are not a gem grade.

These pieces are available in a few sizes and make a decent study specimen. Obviously, these are not high grade specimens, and will never be cut and faceted!

Most of these specimens have 'trigons', an odd triangular shape on one or both ends of the crystal, caused during the formation process.

The pictures you see here are representative of the products and are usually not the exact item you will receive. Where various grades are available we do try to photograph each grade - but some photographs are still on their way!
