Tiffany Diamond Shape Chart

Tiffany offers a wide range of diamond cuts and shapes, ensuring that every ring is as extraordinary as the love it represents. The diamond shape you choose should reflect your unique style and personality.

Round Brilliant Diamonds

The round brilliant cut is one of the most popular diamond shapes for its intense sparkle. Round brilliant diamonds are cut to optimize brilliance, featuring over 56 facets that reflect light and cast tiny rainbows in a breathtaking show of sparkle and contrast. Since 1886, the iconic Tiffany® Setting has featured a triple excellent round brilliant diamond, setting the standard against which all engagement rings are measured.

Princess-cut Diamonds

Beloved for its contemporary style and sparkle, the princess cut is the most popular fancy shape diamond. Princess-cut diamonds are square modified brilliant cuts with pointed corners. Boasting over 50 chevron-shaped facets, this cut is defined by exceptional fire and scintillation. Depending on the length-to-width ratio, princess-cut diamonds can appear square or rectangular.

Emerald-cut Diamonds

Emerald-cut diamonds are sought after for their understated glamour and eye-catching depth. This octagonal step cut features parallel, rectangular facets, and it is the large, open table that highlights the stone’s pure color and icy clarity. The emerald cut is a suitable choice for those seeking an Art Deco-inspired engagement ring style.

Cushion-cut Diamonds

The cushion-cut diamond is also traditionally referred to as the “pillow-cut diamond.” Rounded edges soften the corners of this square or rectangular-cut diamond. A unique spin on the classic round brilliant, the cushion-cut diamond is an excellent choice for any engagement ring setting.

Oval Diamonds

The oval shape is an elegant combination of the round brilliant cut and the marquise diamond. This brilliant cut features shimmering facets that make the light dance and create the illusion of longer fingers. Bold and sophisticated, the oval diamond is a unique shape for the wearer who wants to express their individuality.

Tiffany True® Diamonds

The Tiffany True® diamond is a modern mixed cut that combines a step-cut crown and a brilliant-cut pavilion. Unique to Tiffany, this diamond meets the triple excellent grade, the highest cut grade in the industry. Perfect for the one seeking a modern engagement ring style, this innovative diamond shape displays intense white reflections balanced with subtle rainbows and movement of light.

Pear-shaped Diamonds 

The pear shape combines round brilliant and marquise-cut styles to form a tapered teardrop with an extraordinary display of light. Like oval and marquise diamonds, the flattering pear shape elongates the finger—especially when worn with the point facing the nail. Tiffany pear-shaped diamonds showcase exacting symmetry and are exceptionally beautiful in halo settings.  

Heart-shaped Diamonds

Heart-shaped gems are classic symbols of love, cut with a precise length-to-width ratio to ensure expertly symmetrical curves. Sentimental and as rare as true connection, the heart-shaped diamond is an excellent choice for the classic romantic.

What Is the Difference Between a Diamond Cut and a Diamond Shape?

It’s important to note that diamond cut and diamond shape are not the same thing. A diamond’s cut determines how its facets interact with light. A shape describes the geometric appearance of a diamond. Cut defines what the shape of a rough diamond will be—not the other way around.

 

This is why diamond shapes are often interchangeably referred to as cuts.

How Diamond Shape Affects Sparkle

How Does Diamond Shape Affect Sparkle?

The cut of a diamond shape ultimately determines its ability to sparkle. This is largely because cut determines the number of facets on a diamond and how light travels through the stone. Facets are the flat, polished surfaces on a diamond. Like tiny mirrors, each facet is precisely cut and proportionally arranged to maximize the diamond’s ability to gather in and reflect light. While cut quality is the most important factor behind a diamond’s sparkle, color and clarity grades also matter. The higher the color and clarity grades, the brighter the diamond.
 

At Tiffany, we reject any diamond with noticeable imperfections to the unaided eye.
