Old stock of rough Tunduru gem material

I recently meet an older gentleman who had quite a lot of smaller gem rough from Tunduru, probably from the late 1980’s. There is chrysoberyl, spinel, mixed garnets, sapphire/garnet/spinel/chrysoberyl mix, and Songea sapphire and rhodolite. Does anyone have an interest in this smaller material? Rhodolite is 1gm average, the others range from less than 1ct to 4ct. I am a professional member and have a business listing at IGS. If you are interested in buying any of these, go to my business listing (BRGemstones) and I can send you pictures to your email address. Probably open to best offers.
