A brand-new, unused natural diamond solitaire engagement ring of striking presence, centred by a beautifully proportioned cushion-cut diamond weighing 0.93ct. The centre stone is GIA-certified and graded D for colour with SI1 clarity, presenting exceptional whiteness, intense brilliance, and a lively face-up appearance. The cushion cut combines soft contours with excellent light performance, giving the ring a refined yet confident character that remains highly sought after.

Encircling the centre diamond is a halo of brilliant-cut diamonds that continues elegantly along the shoulders, with a combined weight of 0.35 ct. These additional diamonds amplify sparkle and visual depth, enhancing the overall proportions while keeping the cushion-cut diamond firmly as the focal point. The ring is set in platinum, a precious metal valued for its rarity, strength, and naturally white tone, offering both durability and an ideal backdrop for high-colour natural diamonds. The piece remains completely unused, retaining crisp definition and secure stone placement throughout.

Natural diamonds continue to demonstrate long-term appreciation, driven by a finite supply, rising demand, and stringent certification standards. High-colour stones approaching the one-carat mark are increasingly challenging to source, reinforcing their desirability. Beyond its emotional significance, this ring offers genuine investment potential, combining intrinsic material value with enduring market confidence and long-term collectability within the fine jewellery market.

This ring has a unique GIA serial number laser-engraved on the diamond.
