As an Australian living in Colombo for the past two years, I've been to a few gem shops but this is my jeweller of choice. Mr Isam Salie is now the fourth generation running this shop. The Salie family really know their gems, but most of all they are unfailingly patient whether you are spending $200 or $2000 (or more). I have also found their workmanship to be excellent - Mr Salie recently remade a ring for me and the quality of the workmanship makes it sit a lot better, but also look like a more expensive piece.
