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.
