Lattice diffusion treated sapphires can be any color.

Manufactured diffused sapphire definition.

Lab created diamonds also known as man made diamonds exhibit the same fire scintillation and sparkle as mined diamonds. While doing the treatment there might be some traces of yellow color in the stone s interior. On the mohs mineral hardness scale of 1 to 10 going from softest to hardest sapphire a form of corundum scores 9. Traditional heating of sapphires typically takes 2 3 days and requires extreme temperatures and conditions to achieve the desired results that will make the sapphire more commercial quality.

In some cases sapphire beads are treated with lattice diffusion that can have shallow embeds of colours superficially exhibited on the surface. A sapphire made into a diffused star sapphire cannot be polished for a second time or recut as the treatment is only on the surface of the stone. Parti sapphires show two or more colors. This yellow color can be removed with subsequent heat treatment.

However most buyers never repolish or recut the gemstones set in jewelry. In others it goes all the way through the stone. Manufactured sapphire is synthetic crystalline aluminum oxide that is transparent like glass but harder. To remove or lighten the blue color in too dark sapphires.

This light element is diffused in the sapphire. In some cases the added color is shallow. Discover more about these beautiful and affordable gemstones. Sapphire is transparent durable and scratch resistant.

The treated goods may also be less transparent as the thin diffused surface may exhibit noticeably different optical qualities from the bulk of the cut specimen. Polishing or recutting would remove this surface treatment. This purplish black sapphire from burma has been transformed into a commercially usable pink sapphire after a flux additive is put in the heating process. Lattice diffusion is a treatment process that uses heat and chemicals to diffuse an element into a gemstone to artificially change its color.

Diffusion treated blue synthetic sapphire is inferior to grown blue sapphire in that the treatment is very shallow eliminating the possibility of recutting.
