9Ct Gold 0.15Ct Diamond Solitaire Ring

A diamond solitaire is the quiet workhorse of the jewellery box, and this preloved 9ct example is beautifully unfussy. It carries the gentle romance of a ring that has already been part of someone's story — timeless, understated and ready to be worn every single day.

It is crafted in 9ct gold, a metal we happily defend: hard-wearing, warm-toned and wonderful value, and far too often underrated. A single round diamond of 0.15ct sits claw-set in a raised, open-sided head that lets the light return from every angle, lifted just enough above a slim, polished shank with gently tapering shoulders. The streamlined profile is comfortable for daily wear and pairs effortlessly with plain bands or a layered stack. It makes a subtle engagement or promise ring, or a meaningful gift for an anniversary or milestone. As April's birthstone, the diamond adds a personal note for a spring birthday.
