Our Roots Run Deep

Founded on the diamond fields of South Africa in 1947 by patriarch Barney Laub — Rand Diamonds established a reputation for impeccable quality, integrity, and business ethics. From Laub’s high standard of excellence, Rand Diamonds became one of a select number of companies chosen more than sixty years ago to acquire rough diamonds for cutting and polishing, directly from the source.

Today we continue as the source of polished diamonds for some of the most prestigious retail stores in the world, discreetly supplying them with the finest diamonds to their exacting standards and specification from our US corporation, Rand Diamonds Inc. It is this heritage and market position that is the foundation of Defined Diamonds — our newest innovation.

The tradition of excellence continues with the third generation of our family keeping Barney Laub’s vision alive and growing.

Three generations of supplying the best quality diamonds from the source to the top high-end retailers has given us the knowledge, skill, market positioning, and ability to offer Defined Diamonds to private individuals.


The result of our seven decades of operating diamond-works in Johannesburg, South Africa, and Gaborone, Botswana, and of buying, cutting, polishing, and selling the highest quality diamonds, has put us in the unique position to be at the forefront of diamond innovation today.


Our position at the wellhead of the diamond market makes it possible for us to now offer Defined Diamonds to private individuals at the Polished Trade Price (PTP) — the same market price that high-end retailers purchase their fine diamonds from us. 


Our experience, positioning, and knowledge enable us to hand select diamonds of the types with a track record of being in constant global demand, with consistent value appreciation and good liquidity. All Defined Diamonds are packaged in a beautifully designed stainless steel disc, or a light weight non-metallic disc— a secure, portable, and discreet form of concentrated wealth you physically possess and can depend on anywhere in the world.

Our Promise, Your Guarantee

Whether your goal is to purchase Defined Diamonds to gift them to important people in your life, as a safety net against the unknown, or for jewelry, diamonds you purchase from Rand are of definable quality and sold to you at the Polished Trade Price (PTP). Should you wish to sell your Defined Diamonds at a later date, we offer you our unique Resale Promise.
