“The making of a Harry Winston engagement ring, from the selection of the perfect diamond to its flawless presentation”

Mr. Winston once said :

“Each diamond has a different nature. Each diamond must be handled the way you handle a person.”

Since the House was founded in 1932, the Harry Winston master craftsman has been committed to creating the most exquisite jewels that celebrate and enhance the natural beauty of each individual diamond.  This enduring commitment guides the creation of all Harry Winston jewels, and the philosophy behind the artistry of a Harry Winston engagement ring.  To perfectly highlight a diamond’s true brilliance requires the culmination of efforts between true fine jewelry experts, beginning with the selection of a single stone until it is placed in its own impeccable setting.

The Four Cs

The Four Cs refer to carat weight, clarity, color, and cut. The science behind the sparkle, these guidelines provide solid numbers to help quantify a stone’s quality using charts and scales that are standardized for all gemstones. Carats provide a precise numeration of a diamond’s weight, and from there the precise value of a diamond is further established by assessing its clarity and color, and the precision of its cut. For the master craftsmen at Harry Winston, these figures form the basis for a more complex calculus that will determine the selection and setting of your diamond engagement ring.


Diamond Selection

A Harry Winston diamond is selected for its impeccable quality and character. Completely free from any visible inclusions, each diamond is meticulously cut to reveal its innate brilliance and radiant fire. The precision of a diamond’s cut is what will determine its final size, shape and facets, which all combine to enhance a diamond’s overall beauty. In a well-cut diamond, the facets are subtly angled, symmetrical and balanced, ensuring that light refracts through the diamond in a manner that will optimize and enhance its overall sparkle. Equally important is creating an appealing and balanced shape, where the overall surface of the stone is as intriguing as its luminous, shifting depths.

Harry Winston’s approach has always been to design around the individual beauty of individual diamonds by creating the perfect setting for each stone to shine. Each creation begins with a sketch done by hand in meticulous detail. This allows the designer to convey to the craftsmen the fluidity and overall harmony of the design that brings out the collective beauty of both the setting and the stone.



In creating its fine jewelry designs, the House of Harry Winston has been a pioneer in strictly utilizing platinum settings that allow diamonds to appear as if they are floating in their settings. The most durable precious metal, platinum possesses an ethereal, light color that compliments rather than competes with a diamond’s colorless nature, ensuring that the beauty of the diamond stands at the forefront of each design. Mr. Winston firmly believed that nothing should distract from a diamond's natural brilliance, leading to innovative techniques in craftsmanship, such as the House’s iconic split-prong settings. The setting securely holds the diamond in place, with eight ultra-fine prongs that seamlessly blend into the ring’s design, seeming to disappear behind the radiance of the center stone.

In creating a Harry Winston jewel, what is unseen to the eye is equally as important as the surface presentation. After master craftsmen have placed the diamond, the platinum settings – including those beneath the diamond – are all re-polished to ensure that the luminance of each diamond shines through.


After each detail is meticulously reviewed, the finished jewel leaves the workshop. The culmination of efforts and skills between gemologist, designer and craftsman, each engagement ring represents the high quality standards that are synonymous with the Harry Winston name, and serves as a precious symbol as rare and unique as true love itself.
