Orange Sapphire

Orange Sapphire Gemstone

An orange sapphire is a variety of the mineral corundum (sapphire) that has a reddish-orange color. Orange sapphires are rare, and are typically less expensive than other types of sapphires, such as blue sapphires. They are often used in jewelry and are considered a gemstone.

Treatment

This unusual and rare color for a sapphire is almost never found in nature, and is achieved by the following enhancement methods:

Beryllium diffusion

Impregnation of weakly colored corundum crystals with beryllium under high temperature and pressure. Beryllium has a lower atomic weight and is able to penetrate into the crystal lattice of sapphire, giving it a brighter color. It is important to note that beryllium penetrates quite deeply, and stones 2-3 mm in diameter may be saturated with beryllium to the full depth. Larger stones are colored only at the periphery, while the internal part of a stone is not affected; therefore, the treatment of sapphires by the beryllium thermal diffusion method is possible only on the already cut stones. Samples after beryllium diffusion acquire bright and sometimes not natural orange and yellow hues, and their price is very low: $20-40 per carat. The expert reports on these stones by the world's laboratories always state that they are enhanced with beryllium. These sapphires are used in the cheap jewelry of mass market level, where the fact that the stones are beryllium-enhanced is quite often hidden.

Heat treatment

Treatment of sapphires with insufficient color saturation by means of high-temperature heating. As a result of heat treatment the color of raw material changes into a brighter and richer color throughout the crystal. After cutting such rough we see a beautiful orange color. Because of the huge difference in cost between only heat-treated and beryllium-diffused sapphires, dealers make sure to emphasize that their orange sapphire is only heat-treated and no beryllium diffusion was used

Pricing

• Orange sapphires after heat-treatment are $700-1500 per carat depending on size, color, cut and clarity.
• Orange sapphires after beryllium diffusion - $20-40 per carat, they are not used in expensive jewelry.
