Michael,
I understand that the cost to check for diffusion is expensive but is it too much to ask for for a jewellery maker to understand the difference between heat only and something that is heated with an added mineral? Just as you are confident that the sapphires you procure for faceting is heat only, I expect the Etsy vendor to have some measure of understanding the various treatments of corundum and be confident of their sources.
