Oval Cut Diamonds

The oval cut diamond was first introduced in its modern form by the renowned diamond cutter Lazare Kaplan in the late 1950s, and stands out today as a unique blend of classic charm and contemporary sophistication.  Its elongated shape not only exudes a distinct allure but also offers advantages in terms of brilliance, size appearance, and versatility.

Key features of an Oval Cut Diamond include:

Unique Shape:
The oval diamond is essentially an elongated version of the round brilliant cut. This shape provides a distinctive twist on traditional round diamonds, offering a more elongated, slender appearance. Its soft, rounded edges make it an ideal choice for those who love the brilliance of round diamonds but desire something more unique.

Faceting and Brilliance:
Oval diamonds typically feature 56 to 58 facets, similar to the round brilliant cut. This facet arrangement is designed to maximise light reflection, resulting in exceptional brilliance and fire. The oval cut's elongated shape can also make inclusions and colour imperfections less noticeable compared to other cuts.

Illusion of Size:
One of the most appealing aspects of the oval cut is its ability to appear larger than other shapes of the same carat weight. The extended shape maximises surface area, giving the illusion of a bigger diamond. This feature makes it a cost-effective choice for those seeking impressive size without a hefty price tag.

Versatility in Design:
Oval cut diamonds are incredibly versatile and can suit various settings and styles. Whether set in a simple solitaire, surrounded by a halo, or flanked by side stones, the oval diamond maintains its elegance and character. It's a popular choice for engagement rings but also looks stunning in necklaces, earrings, and other fine jewellery.

Flattering Effect:
The elongated shape of the oval diamond can have a flattering effect on the wearer's hand. It tends to make the fingers appear longer and more slender, an aesthetic advantage that is often considered when choosing an engagement ring.

Choosing the Right Oval Cut Diamond

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

  • Length-to-Width Ratio: This determines the diamond's proportion. A classic oval shape typically has a ratio between 1.3 and 1.5. Preferences vary; some may prefer a longer, more slender oval, while others might like a wider, more rounded shape.

  • Symmetry: Pay attention to the symmetry of the oval shape. Both halves should mirror each other perfectly. A well-proportioned oval cut enhances the stone's overall beauty and brilliance.

  • Bow-Tie Effect: Many oval diamonds exhibit a bow-tie effect, a dark shadow across the central width of the stone. While it's a natural outcome of the cut, the prominence of the bow-tie can vary. Ideally, it should be minimal or unnoticeable.
