The world of precious gems : Thailand

Thailand is the most important world corundum business center..

Because of the political context of the border countries, especially Burma, Thaïland became the sapphires and rubies business turntable.

Rubies and sapphires belong to the same family, corundums.

They have the same composition. The different colours seen are due to chemical modifications (chromium in rubies for example).
The colour is the only parameter token into account for the choice of name.

Red corundums will be so called rubies whereas all others colours will be called sapphires.

Les corindons peuvent présenter des couleurs exceptionnelles qui sont extrêmement appréciées.

Corundums can present exceptional colours which are extremly rare: like the “pigeon blood” red of rubies (an intense red with a dash of blue), the “royal blue” of sapphires ( an intense blue with a dash of violet), and the intense orange with a dash of pink of sapphires called Padparadscha.

These stones are generally included. These inclusions, as emerald ones, are really appreciated. They allow to determine gems origin and treatments that they may have suffer.

Compared with diamonds prices, sapphires prices are reasonable.
Although beautiful rubies, up to 3 carat, prices can be much higher than diamond prices.
