Ruby and Sapphire are both types of corundum, they are differentiated by the amount of chromium content. Chromium content also determines the strength and colour intensity of a ruby. Sapphire have a lower than 0.5% lower content of chromium, Ruby is usually higher than 0.9% of chromium. They have awesome durability and only the vivid saturated colour, known as pigeon blood. Spinel was mistaken as ruby for its vivid red, good saturation colour spinel are priced near to ruby.
Traditionally, fine ruby was sourced from Burma. Currently, they are extremely rare and valuable, due to the low supply of quality ones. The premium price of an unheated vivid red Burma ruby (Pigeon Blood Ruby), can easily cost more than double the Mozambique origin. Existing mines are mainly from Mozambique, Madagascar and Tanzania, with Mozambique being the world’s leading source.
In the market, due to the high demand and low supply of ruby, additional heat treatment has become acceptable. In General, the heat treatment that goes close to the melting point greatly improves the quality of the gem. It minimises pre-existing fine inclusions and even out the colour from the rough. Instead of the usual high-temperature heat treatment, many precious gemstones are treated at much lower temperatures.
This method of low temperature effectively removes any blue colour composition from the ruby and improve the colour. However, gemological laboratories are able to detect low-temperature heat treatment, by close observation of the inclusion.
