Lost River Diamonds Located in Perth, Western Australia, we have been supplying diamonds to jewellers and retailers for over 25 years. The business was started by Jim Lehman and what began almost as a hobby has grown into a successful diamond wholesale business. Jim has retired more recently and the day to day running has been taken over by son-in-law Troy Reany.
Lost River decided many years ago to specialise in coloured diamonds. While the focus more recently has been on diamonds from Argyle - Pink, Champagne and Blue - we have also been building up other colours such as yellow, orange and green.
With the industry changing and more overseas suppliers moving into the market we are proud to be Western Australian owned and operated and will always do what we can to help local Australian owned businesses like us.
