Oval diamond engagement rings are elegant, timeless and increasingly popular — especially among couples who want the brilliance of a round cut with a more unique, elongated silhouette.
This guide, written for buyers across Perth and Australia, explains everything you need to know to select an oval diamond that looks stunning, fits your budget, and is certified for quality.

Why choose an oval diamond?

Illusion of size: Oval diamonds appear larger than round diamonds of the same carat due to their elongated shape and greater surface area.

Finger-slimming effect: Their length visually elongates the finger, making them flattering on almost every hand.

Classic meets modern: The oval combines vintage glamour with modern brilliance — a perfect balance between the round and the marquise.

Sparkle with personality: A well-cut oval offers exceptional brilliance with a distinct “hall-of-mirrors” fire and a minimal bow-tie effect.

The 4Cs + Shape: What to look for in an oval diamond

1. Cut quality (most important)

Cut determines how bright and lively your diamond will appear. Look for:

• Excellent symmetry — both halves should mirror each other.
• Strong light return (avoid dark or dull patches).
• Balanced depth and table percentages.

💡 Tip: View the diamond face-up under natural and LED light, and ask for imaging (ASET or Ideal-Scope) when possible.

2. Length-to-width (L/W) ratio

This ratio defines how round or elongated the diamond looks:

• 1.30–1.35: Slightly rounder, classic look.
• 1.40–1.45: More elongated and dramatic.

Choose according to finger size and personal preference.

3. Carat weight

Ovals look larger face-up, so a well-cut 0.9–1.2ct oval can appear as large as a 1.3ct round. This makes ovals excellent value for their visual impact.

4. Colour

Ovals can reveal more body colour than rounds:

• For white diamonds, choose G–H for best value in white metals, or H–I in yellow/rose gold.
• For fancy colours (pink, yellow, blue), rarity and hue intensity drive the price.

5. Clarity

Inclusions can be more visible in elongated shapes. SI1 or better is a safe range — always verify that the diamond appears “eye-clean.”

6. Certification

Buy only GIA, IGI, or HRD certified diamonds. Certification confirms the 4Cs and any treatments.
For natural fancy colours, ensure the certificate explicitly notes natural origin.
