Oval Engagement Rings: The Complete Buying Guide

Oval engagement rings have become one of the most requested styles in the world. An oval diamond combines the sparkle of a round brilliant with a longer, more elegant outline that flatters the hand.

Quick answer: choose an oval with a length-to-width ratio of about 1.35 to 1.50, check the photos or video for a strong dark bow-tie shadow, and pick a setting with a pave band or hidden halo for extra sparkle.

Why Choose an Oval?

• Looks bigger: an oval has a larger top surface than a round diamond of the same carat weight.
• Flatters the finger: the long shape makes fingers look slimmer.
• Brilliant sparkle: ovals are cut with brilliant facets, similar to a round diamond.
• Versatile: suits solitaire, halo, three stone and vintage styles.

The Best Length-to-Width Ratio

The ratio describes how long the oval is compared with its width. Most buyers prefer between 1.35 and 1.50. Lower ratios look rounder and softer; higher ratios look longer and more dramatic. There is no wrong answer, only personal taste.

What Is the Bow-Tie Effect?

Many ovals show a darker area across the center shaped like a bow tie. A light bow-tie is normal and adds contrast, but a strong, dark one takes away sparkle. It does not appear on a grading report, so look at real photos or a video of the stone before you buy.

Best Settings for Oval Diamonds

• Solitaire: clean and timeless, like our Classic Oval Solitaire.
• Hidden halo: a clean top view with sparkle on the side.
• Pave band: adds sparkle along the finger.
• Bridal set: an oval with a matching eternity band, like our Oval Bridal Ring Set.

Use four or six prongs, or a bezel, to protect the oval's edges. Browse our oval lab grown diamonds and lab grown diamond engagement rings.
