Mixed colour Corundum / Sapphire Specimens

Small rough pieces of various colours of Corundum, a form of Aluminium Oxide, sometimes known as a Sapphire.

Sapphires are often thought of as blue, but any gem-grade Corundum that is not red (Ruby) is correctly known as a Sapphire. However, these are not 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!

Our current stock includes:

    • Small crystals of alluvial Corundum from Sri Lanka, most of which is colourless, an off yellow, or a poor blue. Most of these pieces do show crystalline form but are somewhat weathered.
    • Crystals from Vietnam, red Corundum with blue Corundum - technically a sapphire but realistically these would be referred to as mixed Corundum.
    • Various sizes of crystal fragments from Burma/Myanmar - typically blue, yellow, or off-yellow colours.
    • Crystal fragments from Burma/Myanmar which show good colour banding when backlit, and others which show minor asterism.
