Sapphire with a yellow 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 yellow color was induced by beryllium diffusion processes in the structure of the gems. The baguette cut is very particular. The gems can also be purchased individually, anyone interested can write to us for a quote
