Emerald Cut Diamonds

Emerald Cut Diamonds, known for its clean lines and understated glamour, has a unique charm that appeals to those who admire classic beauty with a modern twist.

The emerald cut has its origins in the techniques used for cutting emeralds in the 1500s. Gem cutters discovered that emeralds were less likely to chip if cut with stepped facets. This technique was later adapted for diamonds, leading to the birth of the emerald cut. Its popularity surged in the Art Deco period of the 1920s, when its clean lines and symmetry complemented the era's aesthetic.

Key features of an Emerald cut diamond include:

Rectangular Facets: The most defining characteristic of an emerald cut diamond is its long, rectangular facets, which are step-cut into the stone. This cut creates a hall-of-mirrors effect, offering a different type of sparkle compared to the traditional brilliance of round cut diamonds. The step cuts emphasise clarity, as they draw attention to the stone's transparency.

Elongated Shape: Emerald cut diamonds typically have an elongated rectangular shape with cut corners. This shape not only makes the diamond appear larger but also lends a slenderising effect on the finger, making it a popular choice for engagement rings.

Large Table and Open Facets: The cut’s large table (the top flat facet) and open facets are like windows into the diamond. This feature highlights the purity and clarity of the stone, making inclusions and colour more noticeable. As such, higher clarity and colour grades are often preferred for emerald cut diamonds.

Subdued Fire: Emerald cuts do not exhibit as much "fire" or colour refraction as round brilliants. Instead, they offer a subtler, more sophisticated sparkle. This understated brilliance often appeals to those who prefer a more elegant and less flashy look.

Versatility in Design: The clean lines and simple geometry of the emerald cut make it incredibly versatile for various jewellery designs. It pairs beautifully with both vintage and contemporary settings, making it a timeless choice for engagement rings, necklaces, and other fine jewellery.

Choosing the Right Emerald Cut Diamond

When selecting an Emerald cut diamond, consider the following factors:

  • Prioritise Clarity and Colour:

    • Clarity: Since emerald cuts don't hide imperfections well, look for a diamond with a high clarity grade. VS1 or VS2 clarity grades often offer a good balance between quality and value.

    • Colour: Emerald cuts also tend to show more colour. Consider a diamond in the G-H colour range for a good balance of colourlessness and value. However, if the diamond is set in yellow or rose gold, a slightly lower colour grade might still look colourless in context.

  • Carat: Carat weight affects the size of the diamond. Keep in mind that emerald cut diamonds often appear larger than round diamonds of the same carat weight due to their elongated shape.

  • Proportions and Symmetry: Proportions in an emerald cut diamond are vital. Look for good symmetry and proportions that are pleasing to the eye. Avoid diamonds that are too shallow or too deep, as they can negatively impact the stone's brilliance.

Emerald Cut Ratio

Emerald cut diamonds are renowned for their elegant proportions, typically featuring a length-to-width ratio ranging from 1.3:1 to 1.6:1, which accentuates their classic, elongated shape. This range allows for a subtle variation between a longer, more slender appearance and a shorter, more squared silhouette, catering to individual preferences in aesthetics and style.
