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 diffusion processes in the structure of the gems. It is recommended to mount them with the pavilion facing upwards. The gems can also be purchased individually, for those interested can write to us for a quote
