What is an oval cut diamond?

Definition
An oval cut is a faceted, elongated gemstone shape, rounded at both ends and wider in the middle, cut in the brilliant style so it has the same kind of sparkle as a round brilliant. The elongated shape makes the stone appear larger than a round of the same carat weight, and on the finger it creates a slimming effect that many people find flattering. Oval cuts have become one of the most popular choices for engagement rings and suit a wide range of setting styles.
Frequently asked questions
- Does an oval cut look bigger than a round cut?
- Yes, an oval typically faces up larger than a round brilliant of the same carat weight, because its elongated shape covers more surface area. This makes it a popular choice for buyers who want maximum visual size.
- What is the bow-tie effect in oval cut diamonds?
- The bow-tie is a dark shadow that can appear across the centre of an oval, and many other fancy-shaped brilliant cuts. It happens because of how those facets reflect light, and the strength of it varies from barely visible to quite obvious. It is worth viewing an oval in person to assess it.
- What ring settings suit an oval cut?
- Oval cuts work well in a wide range of settings. A simple solitaire lets the shape speak for itself, a halo emphasises the elongated outline, and a three-stone setting pairs the oval beautifully with smaller side stones. East-west settings, with the oval set horizontally, are also popular.
