Last year I purchased a diamond eternity ring from Raw Diamond Jewellery Shop in Kalan, Turkey. When we bought the ring, after visiting various shops we were given a 5 year exchange guarantee in an 'International Certificate of Guarantee'. Unfortunately, one year on, one of the diamonds has come out of the ring and is lost. I have contacted Abdul via e mail four times, rang the shop and spoke with a man who 'spoke little English' (funny that - they can speak excellent English when they want to sell to you) and telephoned the owner's mobile and left a message. Obviously this 'guarantee' means nothing. We searched through the jewellers in Kalkan and decided on Raw Diamond as we found them professional. Obviously not as professional as we first thought as after the sale has been made they do not want to know. Businesses like them give jewellers in Kalkan a bad name. Can anyone help with where to turn from here? We have now lost faith in them and would be reluctant to return the ring with the fear of them possibly replacing the stone with an inferior jewel.
