The Snap Lake Mine, De Beers' first mine outside of Africa, is unique in Canada. Built on the shore of Snap Lake, 220 kilometres northeast of Yellowknife, the mine is Canada's first completely underground diamond mine. The Snap Lake ore body is a 2.5 metre thick dyke that dips an average of 12-15° from the northwest shore down under the lake. It is unlike most diamond-bearing kimberlite deposits which are known as 'pipes' due to their conical or carrot-like shape.

HRA is the only Canadian member of an elite group of diamantaires selected to receive rough diamonds from De Beers, the world's foremost producer of diamonds. Such privileged standing is granted only to the most reputable and competent manufacturers, and allows us to assure our customers a consistent supply of some of the world's finest diamonds.

Crossworks is supplied with rough diamonds from three Canadian mines: the De Beers Snap Lake and Victor Mines in the Northwest Territories and northern Ontario, and the Rio Tinto Diavik Mine in the Northwest Territories.

In 2011, HRA was chosen to be an Authorized Partner for Argyle Pink Diamonds.


The core of Crossworks' production is carried out at our three Canadian facilities in Sudbury, Ontario; Yellowknife, Northwest Territories; and Vancouver, British Columbia. The HRA Group also owns and operates the Rydiam Saigon facility in Vietnam.

Propelled by the same guiding principles as our parent company, everything we do at Crossworks is designed to add value to our products so that our customers may pass on to their clients only the most exquisite diamonds available. The key to our success is bringing innovation to the long-standing, reliable practices of the industry.

A Crossworks diamond is the intersection of highly-skilled human craftsmanship and state-of-the art technology. Each of our artisans

have skills that combine hands-on working experience and contemporary techniques that strengthen traditional means of assessing, cutting, and polishing. To maintain our exacting standards of quality, to drive development forward, and yet to remain agile, we continually re-invest not simply in technology, but also in the professional skills of our people: every diamond is unique, and every Crossworks diamond has been shaped to perfection by a skilled team. We are the only North American manufacturer of Canadian diamonds, transforming rough beauty into a refined brilliance that will illuminate fantasies large and small. Our road to the future is paved with tradition.


Each of our facilities is managed by a master cutter
with many years of hands-on experience and a deep
knowledge of the industry and its many regions: North
America, Europe, Africa, Asia.

Crossworks operates three state-of-the art manufacturing facilities in Canada: in Sudbury, Ontario; Yellowknife, Northwest Territories; and Vancouver, British Columbia. We also operate a large cutting and polishing facility in Ho Chi Minh City, Vietnam. Our operations in Sudbury and Yellowknife are situated in proximity to the mines which produce our diamonds, contributing significantly to the local economy with employment and by developing local expertise. Our Canadian diamonds are prized in North America and around the world, and are distributed through a large network of retailers.

Each of our facilities is managed by a master cutter with many years of hands-on experience and a deep knowledge of the industry and its many regions: North America, Europe, Africa, Asia. Each diamond is individually analysed on site with the aid of the latest

computer-imaging software, to determine its final size and shape. Teams of highly skilled and experienced cutters and polishers produce an array of cuts using a combination of traditional methods and modern tools, such as laser saws. Our rigorous in-house system of quality control guarantees that each Crossworks diamond will be cherished forever.

With our commitment to investing in the finest employees, training programmes, and technological advances, as well as our sensitivity to changes in the product demands of the industry, we believe we have created a model of consistency and expertise that will serve us well into the future - and, most importantly, to continue to bring our customers exceptional diamonds.

Diamonds are unlike anything else on this earth. But they need a setting and the setting can make all the difference. Well-considered, strategic branding is like an artful setting: it accentuates the finest points on a diamond and gives it prominence. And the way you promote, or set, your diamonds, has a direct influence on your sales: they can be brightened through intelligent branding. We know

that sourcing, cutting, and polishing some of the world's finest diamonds is only part of the job. Presenting them to your customer in a way that enhances their desirability is the other part. To do this, HRA offers highly intelligent branding: distinctive and sophisticated packages that will add value for the retailer.
