Why Choose Us
Dukes Gold & Diamond Exchange is an owner-run business built on a long and proud heritage in buying and trading precious metals. With experienced and qualified buyers, free appraisals and immediate payment by cash or EFT, Dukes is committed to making every selling experience safe, transparent and comfortable.
Our Story
What started with a family interest in gold and diamonds flourished in the late 1980s into a thriving business. Over the years, the family opened two highly successful businesses in Johannesburg, which were later sold.
In recent years, Dukes Gold & Diamond Exchange has reshaped and restarted this long-standing heritage, bringing its experience and passion for precious metals back to the market.
What Makes Dukes Different
At Dukes, everything is built around three simple principles:
Integrity. Honesty. Safety.
The team is committed to ensuring clients feel comfortable throughout the selling process while helping them achieve the maximum possible value for their items.
