Hi all
We have been playing with some ideas to use some of the stuff we mine in a unique way. Although our main product is sapphire, we have always thought there was a lot of potential in using black spinel. This is a gem that we find in association with our sapphire - it has a hardness of 8.0 and is very consistent so you get almost no cracks or flaws when cutting or polishing. We have thought this would be a good alternative to black diamond in particular as this seems to be exorbitantly expensive these days and even with treatment, very difficult to cut and polish - particularly in larger sizes. Black spinel does not have any of these problems and has natural colour without the need for treatment and available in a range of sizes. Maybe an option to use with diamonds as a white-black-white contrast?? Have not explored this fully yet.
We started cutting this gem in a range of shapes for jewellery and progressed into making beads - we have been very pleased with the results. Have attached a picture of some of the faceted ones for your interest - would be interested in comments.
Cheers Andrew Lane
