About Ruby / Fracture-Filled
The process of fracture filling ruby is a recent innovation that began around 2004. Rubies of good color, primarily from Madagascar, can be enhanced using a combination of heat treatment with lead glass. Because the refractive index of corundum and lead glass are very similar, light can travel through the stone unhindered. Fracture-filled rubies can often be bought in exceptionally large sizes that heat-only ruby would almost never be found in, and at a fraction of the cost of heated or untreated ruby. So they are of excellent value, as long as the treatment is disclosed and the price is appropriate.Recensioni dei clienti verificati | ||||||||||||||||||
