A popular shape for an elongated feel, an oval diamond in a north-south orientation is certainly a timeless design. For a unique twist with an oval diamond, try an east-west orientation, or even setting the diamond at an angle for a truly one-of-a-kind engagement ring.

With just the right amount of curve and angle, a pear has a similarly elongating visual effect on the finger. Paired with diamond pavé shoulders that taper to a point, or a twist that connects at an angle, a pear diamond shines with the combination of curves and angled geometry.

Another elongated cut, the emerald cut diamond features a structure of strong vertical lines that make it the perfect choice for a geometric design. An east-west setting is another unique way to set this cut, as are bezels and halos that highlight the angled corners of the emerald shape.

The cushion cut is an overall square shape with softly rounded corners, and is perfectly balanced for both traditional and custom designs. For a literal twist, a kite setting adds a dynamic visual by simply breaking the strong parallels of the diamond cut and the shoulders of the ring.

For an elongated look with bountiful brilliance, a radiant might be the perfect match for you. Keep in mind that radiants come in an array of proportions, so a square radiant will offer a similar silhouette to an Asscher cut, but with more brilliance.

With large domed facets, rose-cut diamonds have a simultaneously uniquely modern and vintage appeal. Set in a halo or a sleek solitaire, a rose-cut is right at home. Paired with unique design details, rose-cut diamond rings take on a sense of wonder and magic.

Old Mine Cut

As an early example of diamond cutting, Old Mine Cuts feature large facets, and an often asymmetrical or mostly cushion shape due to the early technology available to diamond cutters. Set in a classic ring or a more elaborate custom design, Old Mine Cut diamonds can feel both vintage and modern depending on their setting.

Old European Cut

As technology and time passed, lapidaries were able to achieve greater precision in their work. Old European Cuts represent the phase of diamond cutting after Old Mine Cuts, and show an evolution from a more cushion-like shape to a more perfect round. We love an Old European Cut as a center in geometric vintage designs to play up their more perfect symmetry.

Raw Diamonds

An unfaceted or raw diamond can be a wonderful focal point for a modern or rustic ring design. It’s amazing to see the raw crystal structure of the diamond material without polishing, just as it’s found in nature.
