Sam Dial Jewelers only buys and sells conflict free diamonds. Through a system of warranties implemented by the United Nations via the Kimberley process about ten years ago, fewer than 1% of the diamonds traded today were ever conflict diamonds.
We suggest that you read the following websites: www.diamondfacts.org and www.kimberleyprocess.com. These sites do a really good job explaining the system of warranties, what the kimberley process is, and what it means to you as the end diamond consumer. Also, you can learn about the role diamonds play in developing nations.
