Phoenix and Sun City

As a Master IJO Jeweler, Diamond Jim travels to the heart of the diamond industry in Antwerp, Belgium twice a year to handpick diamonds for our customers.

At Diamond Jim’s, we take diamonds very seriously. We aren’t just jewelers, we are also diamond brokers. As a diamond buyer, Diamond Jim has access to the incredible inventories of diamonds that can only be found in Antwerp. We are able to search through thousands of carats of diamonds, selecting only the most perfect diamonds for our customers – at the lowest prices!
