About Us

We’re changing the way people buy diamonds and jewellery. Leandro Eckardt founded Grand Diamonds in April 2010 at the tender age of 22, since then he has created an outstanding reputation in the diamond trade locally and internationally, focusing on only the best quality gems and providing award winning workmanship on all their jewellery pieces. With entrepreneurship running through his veins and an immediate attraction to diamonds and gemstones he saw an opportunity to revolutionize the way people shop for diamonds and jewellery.

Let’s be honest when you shop for diamonds and jewellery the traditional way it’s quite daunting, you have no clue what you are spending all this money on and you just hope the salesman guides into making the right purchase.

At Grand Diamonds we prefer to go a different route, we offer a personal service with a certified and trained diamond expert thus giving you the knowledge and guidance to make an informed decision with absolutely no obligation to buy. We work individually with each client taking their ideas and budget into careful consideration to create the perfect masterpiece. We also offer a world class website for you to browse various designs at the comfort of your home or workplace which includes a live chat function to answer any questions for instant gratification.

We believe that you should not pay premium to own a high-quality diamond or jewellery piece. Our unique business model and the fact that we purchase directly from the mines site holders allows us to pass the savings on to you. We’re proven to be at least 30% cheaper than your traditional jewellery store.

After many years of diamond trading and developing relationships with only the world’s most reputable diamond cutters Leandro has gained access to the world’s top gems and with a team behind him that carries over 20 years’ experience in jewellery manufacturing we offer international award winning quality to ensure a lifetime of value.

Our mission is to provide our clients with authentic South African Made diamond & gemstone jewellery by offering exceptional service with uncompromising quality at an affordable price.

Visit our Cape Town Showroom to experience the true pleasure of South African diamonds and gemstone jewellery or contact us via email for any of your diamond and jewellery requirements.


Our GIA certified diamonds are Lazer inscribed, meaning the certificate number is engraved on each diamond for you to verify on collection or delivery.


The Grand Diamonds procurement policy:

At Grand Diamonds, we only purchase diamonds through the largest and most respected suppliers who, like us, proudly adhere to and enforce the standards established by the Kimberley Process. All our diamonds are warranted to be conflict free and 100% natural, we do not deal in Lab grown or treated diamonds whatsoever. If one of our suppliers was ever found to be in violation of that process, we would immediately sever that relationship. We will continue to support and promote any process that works to uphold legitimacy in the diamond trade.
