About the Stones

The centre is a 0.30ct natural oval-cut emerald, small enough to be daily-wearable but large enough to read as a recognisable emerald centre stone on the finger. The 0.20ct of diamond accents are natural mined stones in G/H colour and SI clarity. The proportional balance is roughly 60% emerald to 40% diamond by weight, which makes this ring's centre stone the visual anchor while the diamonds add brightness around it.

About the Setting

The 18kt yellow gold setting (750 purity) provides a richer, warmer gold tone than 14kt yellow gold and pairs particularly well with the green of emerald. The four-prong centre setting elevates the oval emerald above the band line, helping the centre read larger than its 0.30ct weight alone would suggest. This is one of the smaller emerald and diamond rings in our 18kt collection by carat weight, but the metal grade and proportional balance keep it firmly in the fine-jewellery tier.

Why Choose 18kt Yellow Gold for an Emerald Ring

18kt yellow gold contains 75% pure gold (marked 750) compared to 14kt at 58.5% pure (585). The higher gold content gives 18kt a richer, more saturated yellow tone that sits more dramatically against an emerald's green. 18kt is also slightly softer than 14kt, so it shows wear a touch faster, but most buyers who choose 18kt do so for the visual impact. For a relatively small emerald like the 0.30ct centre in this ring, the 18kt setting helps the stone read warmer and more substantial.

Frequently Asked Questions

Is the emerald natural?

Yes. The 0.30ct oval-cut centre is a natural mined emerald. The 0.20ct of diamond accents are also natural mined stones, in G/H colour and SI clarity.

Why 18kt yellow gold rather than 14kt?

18kt yellow gold has higher pure-gold content (75% vs 58.5% for 14kt) and produces a richer, more saturated yellow tone. The trade-off is that 18kt is slightly softer than 14kt. For an emerald centre stone, the warmer 18kt yellow tone often pairs more dramatically with the green of the emerald.

Is this a small ring?

Yes, this is intentionally a petite oval emerald and diamond ring. The 0.30ct centre and 0.20ct of diamond accents (0.50tcw total) make it lighter on the finger than larger oval emerald rings in our collection. It's well-suited for daily wear or as a stacking partner with other rings.

Can it be worn as an engagement ring?

Yes. While our larger emerald engagement rings are built around 1ct-plus centre stones, this 0.30ct oval emerald centre is suitable as an engagement ring for buyers who prefer a smaller, more daily-wearable scale or want to stay within a particular budget.

Is the ring resizable?

Most settings of this construction can be resized by one to two sizes. Contact us to confirm sizing options before ordering.
