Lost River Diamonds are located in Perth Western Australia less than one mile from Argyle's coloured diamond head offices. We are extensive buyers of fancy coloured diamonds from all over the world having travelled frequently to India, Brazil South Africa, Antwerp and New York to source the best range of coloured diamonds we can get.

We have the good fortune of seeing a lot of pink diamonds before anyone else and along with our range of fancy shapes in browns(cognacs) and yellows we can supply direct from the source.

We are currently developing our own mine in South Africa and soon hope to be able to provide diamonds with a complete history from rough to finished stone.

We have also established a close working arrangement with a couple of DTC sightholders to access top quality white diamonds in all shapes and sizes. Our grading standands are the highest and more importantly the most consistant possible. We invite you to try our prices and be pleasantly supprised.
