There’s no such thing as a “standard” love story. It makes sense that engagement ring shoppers tend to look beyond the traditional round brilliant diamond or classic oval shape. Couples are in search of a style that feels more personal, expressive and entirely their own.

Whether you’re drawn to geometric lines, elongated silhouettes or vintage-inspired cuts, each shape helps determine the magic of your ring.

Sarah’s passion for our customers and their love stories inspires every design. We’d love to help you discover a diamond that feels like an extension of you and your relationship. One that’s thoughtful, distinctive and designed for a lifetime of unordinary.

Four diamond engagement rings from the myriad collection.

The difference between diamond shape and diamond cut

A diamond’s shape refers to its overall outline or silhouette. Think oval, hexagon, kite or cushion.

A diamond’s cut characterizes the faceting style of the stone itself, which impacts how the diamond reflects light. Brilliant cuts maximize sparkle, while step cuts create a hall-of-mirrors effect with a clean, linear twinkle.

Together, shape and cut create the overall soul of a diamond.

Unique diamond shapes to consider

Exploring alternative diamond shapes doesn’t mean you don’t love tradition. Your union is unlike any other. Don’t hesitate to unleash your design language in a way that captures both your love story and your personal style.

Cushion cut diamonds

The Isla Cushion Ring

Cushion cut diamonds are technically a shape, not a cut. These soft, romantic diamonds blend vintage charm with contemporary elegance. Featuring gently rounded corners, they create a poetic look compared to sharper geometric shapes.

Different diamond cut styles

Beyond shape, a diamond’s cut dramatically influences the look and feel of a diamond.

Did you know that the process of cutting diamonds still relies on a series of exacting steps? Diamond cutters saw, brute, facet and polish each stone to highlight a natural diamond’s brilliance and timeless value.

Brilliant cut

The Josephine oval diamond engagement ring on a pink textured surface.

Designed for maximum dazzle and shine, brilliant cuts feature numerous facets that capture and reflect light, creating the classic “diamond sparkle.” The 17th century was a time of prosperity and candlelit dinner parties. Enter the demand for maximum brilliance, which ushered in a new cut that reflected more light through the top of the stone.

Step cut

Step cuts embody long, linear facets that create a clean, sophisticated glow rather than intense brilliance. They’re beloved for their understated elegance and architectural feel. The step cut grew in popularity when the Asscher family from the Netherlands patented their square-shaped step cut. Further adored during the Art Deco era, this cut defined the jewelry aesthetic of the 1920s. If the step cut wasn’t yet on one’s radar, it rose to fame when the Prince of Monaco proposed to Grace Kelly with a massive emerald-cut engagement ring in 1956.

Rose cut

The Athena Rose Cut ring

The rose cut is believed to have first originated in India during the 15th century. By the 1520s, European gemstone cutters had adopted this cutting technique as one of the highest standards for fine diamond jewelry. Its flat base, domed top and triangular facets are arranged to resemble the petals of a rose bud. This cut’s subtle shimmer and Pre-Edwardian style make it especially popular in vintage-inspired designs.

Old mine cut

14k yellow gold ring with a 2.05 ct elongated old mine cut natural diamond with a ridged triple band on a white surface.

Old Mine cut diamonds carry a beautiful sense of history and character. Their hand-cut faceting creates a warm, candlelight sparkle. Along with large, floral facets, the open culet makes this cut uniquely imperfect in the best possible way. In fact, during their most popular eras, the Georgian and Victorian periods, artisans hand cut each diamond based on the stone’s rough, natural one-of-a-kind form.

Selecting a unique diamond shape that speaks to you

Only you can decide which diamond shape best matches your love story. It’s deeply personal, yet there are a few factors that can help guide the process:

Think about your personal style. Do you gravitate toward minimalist architecture? Vintage details? Organic, softer silhouettes? Your engagement ring should complement the aesthetic you love.

Consider proportions. Elongated shapes can create a more dramatic, elegant appearance, while geometric shapes feel bold and artistic.

Decide what matters most. Do you want maximum brilliance and sparkle? Clean lines? Vintage charm? Understanding what you’re most drawn to can help narrow down the right shape and cut combination.

Don’t shy away from something uncommon. Some of the most memorable engagement rings come from choosing a shape that simply feels right, even if it’s less traditional.

Explore one-of-a-kind designs. Limited designs or one-of-a-kind settings often showcase unique diamond shapes. Curations like those in our Myriad Collection feature inspired designs that celebrate the individuality of each stone. When a one-of-a-kind piece of ours is sold, it may never be replicated the exact same way again.
