Sapphires with a yellow-orange color, probably obtained by beryllium diffusion treatment. Good transparency when observed with a 10x lens
Pure corundum, or aluminum oxide, is a completely colorless mineral. The presence of elements foreign to its chemistry give it its color; hence the name of the variety (sapphire for blue and ruby for red). The lot presented is of sapphires, whose color was induced by beryllium diffusion processes in the structure of the gems.
