Introducing the Celestial — an 18ct gold diamond ring that catches light from every angle.
This 18ct two-tone gold ring is built around a striking marquise-cut diamond of 0.28ct in G colour, flanked by two brilliant round diamonds of 0.16ct total weight. The marquise's distinctive elongated profile creates an elegant visual sweep across the hand, while the surrounding rounds amplify its brilliance. Hand-finished in our Chichester workshop, each stone is set with precision and every edge polished to perfection, so the diamond ring gleams with the depth and character that only mastercraft can achieve.
Whether marking an engagement, anniversary or a moment you want to treasure, this ring suits both everyday wear and special occasions. The two-tone finish — a timeless blend of white and yellow gold — brings contemporary sophistication to a classic setting. Hallmarked 18ct gold, it arrives ready to wear and complements any wedding band with ease.

Ensure a perfect fit for your ring by using one of the methods below:
- Measure an Existing Ring: Measure the inside diameter (mm) of a ring that fits the same finger perfectly.
- Measure Your Finger: Wrap string or paper around the base of your finger. Mark the overlap and measure the length (circumference) against a ruler.
Expert Tips: Measure at the end of the day when fingers are warmest. If your knuckle is significantly larger than the base of your finger, size up.
