Understanding the Difference Between Diamond Shape and Diamond Cut

While the terms 'diamond shape' and 'diamond cut' are often used interchangeably, they refer to different characteristics.

Diamond shape denotes the physical, external geometry of the diamond. It dictates the overall look of your diamond engagement ring and is primarily a matter of personal preference.

The diamond cut refers to how well the diamond was cut from its rough state. Facet arrangement, symmetry, and proportions are factors that determine  the level of brilliance (white light reflection), fire (flashing colors), and scintillation (sparkle effect when the diamond is moved) an individual diamond will possess. Choosing the right diamond shape and cut is integral to finding a diamond that not only looks beautiful but also performs brilliantly under light.

As you explore the world of diamond shapes and cuts, remember that the best choice is one that reflects your style and resonates with you.

Emerald Shaped

The emerald-shaped diamond is distinguished by its rectangular appearance, trimmed corners, and step-like facets. The emerald-shaped diamond is prized for its crisp, angular lines and sparkling brilliance. The ideal length-to-width ratio is 1.35-1.65; however, ratios between 1.25 and 1.75 are also thought to be acceptable.

Oval shaped

A longer interpretation of the round brilliant is the oval. This lovely diamond shape results in a gemstone with considerable brilliance and fire if it is properly proportioned. In comparison to a round brilliant with the same carat weight, the oval shape has a higher surface area. It might appear bigger while displaying the same amount of fire and brilliance.

Pear shaped

The pear-shaped diamond's teardrop silhouette converges into a single point while lengthening the fingers and balancing sparkling facets with a lovely proportion and depth. Due to its combination of round and marquise forms as well as their symbolic teardrop shape, pear-shaped diamonds, once selected for fine jewelry instead of engagement rings, have recently grown in popularity. Our pear-shaped diamond engagement rings showcase gemstones with a balance of proportion and depth as a result of  their perfect taper.

Which diamond shape sparkles the most?

The round brilliant diamond is the shape considered to possess the most "sparkle". Technically defined, "sparkle" refers to the fire and scintillation of a diamond. The 57 facets of a round brilliant are highlighted by its rounded form and angled sides. Not every round brilliant is guaranteed to have great sparkle. The most important factor when looking for the best sparkle is finding a diamond with the best cut. After the round brilliant, oval-, pear-, and marquise-shaped diamonds are regarded to have the best sparkle.

Which diamond cut looks the largest?

Comparing diamonds with the same carat weight, emerald, pear, marquise, and oval diamond shapes appear to be the longest. The illusion of having a larger diamond comes from their elongated shapes. These distinctively elegant diamond shapes are perfect if you are looking to maximize the center stone size of an engagement ring.
