Harry Winston emphasizes quality rather than quantity. Our rigorous standards for diamond grading and decades of expertise ensure that every aspect of a Harry Winston diamond engagement ring is the absolute finest available in quality and workmanship. The shopping experience at our stores is also unique; we encourage clients to sit down in the calm atmosphere of our salons and take the time they need to be educated and guided by our knowledgeable sales executives to select the perfect ring.

You do not need an appointment to visit Harry Winston. If you would like to call ahead, however, we would be happy to set up an appointment and pre-arrange a selection of rings to show you based on your particular needs.

Before a diamond can become a Harry Winston diamond, it must pass strict quality assurance criteria that go far beyond the Four Cs. Our expert team of gemologists evaluates diamonds differently—taking into consideration not only whether a diamond looks good on paper, but whether it meets Harry Winston’s visual standards for beauty and brilliance. Two diamonds can have the same Four C characteristics, but if one has not been cut well, they will not sparkle equally. Our gemologists choose diamonds according to a more complex set of criteria, including a high level of connoisseurship which cannot be translated into any gemological report.

The importance of color versus clarity comes down to personal preference. Harry Winston only carries diamonds that are of D, E or F color and greater than VS2 clarity. These high standards ensure that every ring you see in our store will feature a diamond of truly excellent beauty and brilliance. Please see our guide on How to Choose a Ring for more information.

In 1953, the Gemological Institute of America introduced what is now the industry standard grading scale for colorless diamonds, grading them on a color scale from D to Z and a clarity scale from Flawless to I3. At the time the new grading system was introduced, several grading classifications were used that employed numbers, letters and descriptive words. This caused confusion when comparing two diamonds that had been graded with different nomenclatures. D was agreed upon as a starting point to differentiate from the previous systems.

Harry Winston carries round brilliant-cut, square emerald-cut, emerald-cut, cushion-cut, radiant-cut, oval, pear, marquise and heart-shaped diamonds.

The Asscher-cut is essentially a trade name that describes a square emerald-cut diamond with wide and steep cut corners, a small table and a built up crown. Harry Winston does carry this special make of square emerald-cut diamonds.

We work with each client individually if they decide they would like to upgrade or sell their diamond. It is our goal to continue a relationship with our clients as their jewelry tastes and needs grow and evolve.
