Diamond Cut

Diamond cut refers not only to a diamond’s physical shape, but also to how well it interacts with light. A precisely cut diamond reflects light beautifully back to the eye, creating the dazzling sparkle we associate with a high-quality stone. In contrast, a poorly cut diamond may look dull or lifeless—even if it has great color or clarity.

A superior cut doesn't just enhance brilliance—it also improves visual size. Diamonds cut with ideal proportions often appear larger than deeper-cut diamonds of the same carat weight, thanks to their better light performance and spread.

What is an Ideal Cut?

An Ideal Cut is typically associated with round brilliant or princess-shaped diamonds that are proportioned to maximize light return. These diamonds show exceptional polish and symmetry, allowing them to reflect and refract light with incredible intensity—sending brilliance and fire through the table and crown. Ideal cuts are designed to achieve maximum sparkle and are highly valued for their precision.

Hearts and Arrows (True Hearts™ Equivalent)

Diamonds cut with exceptional optical symmetry reveal unique internal patterns. When viewed from the top, you'll see a pattern resembling arrows. Viewed from the bottom (pavilion), eight heart shapes appear—each one precisely formed.

This visual precision is the hallmark of what’s often called a “Hearts and Arrows” diamond. These diamonds are symbols of craftsmanship and balance, representing a level of perfection that can only be achieved through exact cutting and alignment.

Some jewelers refer to these as “True Hearts™” or by other names like “Hearts on Fire” or “Leo Diamonds.” Regardless of the name, the common feature is perfect internal symmetry and light return. At a professional level, such diamonds are often analyzed under 100x magnification and evaluated from every angle—including 360° views—to ensure their optical excellence.

Brilliance, Fire & Scintillation

A well-cut diamond delivers a trio of visual effects:

  • Brilliance: The white light reflected from the surface and inside the diamond.

  • Fire (Dispersion): The rainbow flashes of color produced when light disperses within the stone.

  • Scintillation: The sparkle and flashes of light that occur when the diamond, viewer, or light source moves.

Together, these qualities create the mesmerizing appearance that makes diamonds so sought-after. A high-quality cut is what brings them to life.
