Heat enhancement sapphire

This method of heat enhancement, is commonly use on other coloured gemstone, such as Ruby, Emerald, except for Spinel which is usually unheated. With extreme high temperature, near to the melting point, it filled up natural cavities (inclusion) for better clarity. Improve uneven distribution of colour, enhance the saturation of the sapphire. This drastic improvement in the colour hue and clarity, soften the price for sapphire which make them more affordable, as compared to the unheated ones.
Colour diffusion Sapphire
However colour diffusion, which introduce artificial chemical for colour enhancement, is considered as unnatural. Do take note on this colour diffusion written on the gemstone certification. Although certification indicate that they are “Natural”, this simply because they are not lab created, such as synthetic gemstone. They might look real intense and brilliant in colour, but of no value. Same goes to B / C grade Jade, they might look intense green, but huge difference in price and value as compared to grade A jade.
