I have been buying and selling gems for a while. I am not a professional in the sense I do not have qualifications, but I have had a fair amount of experience in gem rough and cut materials. I purchased rough from Swala Gems in Arusha, Tanzania, and had it cut in Thailand.
I also have my own faceting machine, a Raytech Shaw. I do some cutting and recuts of damaged gems for my own interest.
I have spessartite garnet, tourmaline and spinel available for interested jewellers.
