Until the discovery of the Mong Shu mine in Burma, Siam rubies were accounting for the major part of all rubies supplied to the international jewellery industry. Today the Siamese ruby deposits are nearly exhausted and productivity has dramatically decreased.



In terms of prices, Siam rubies are situated between the heated Mong-Shu rubies and the unheated Mogok rubies.
We do have long established contacts in Chantaburi and Bangkok and we select personally our gems for you there.



You can count on our very best and competitive prices for these beautiful and rare Rubies.
