A brand-new, unused GIA-certified platinum diamond engagement ring that beautifully combines vintage glamour with modern sophistication. A striking 0.40ct marquise-cut natural diamond is at its centre, graded D for colour and SI1 for clarity. With the highest possible colour grade, this diamond radiates icy brilliance. At the same time, its elongated shape and pointed ends create a flattering, elegant silhouette that maximises sparkle and presence on the finger.

Encircling the marquise diamond is a halo of brilliant-cut diamonds, meticulously arranged to enhance its brilliance and lend a sense of grandeur. The sparkle continues along the shoulders, where additional brilliant-cut diamonds are set to create a seamless, flowing design. These accent stones, with a combined weight of 0.25ct, are graded H-I in colour and VS1-VS2 in clarity, offering refined contrast and a soft shimmer that perfectly complements the centre stone.

Crafted from luxurious platinum and weighing 3.39 grams, this ring offers exceptional strength, a luminous finish, and timeless appeal. Accompanied by a GIA certificate and an independent valuation of £3,866.00, this piece presents a rare opportunity to own a beautifully designed, high-quality engagement ring. A captivating symbol of love and commitment, it is ready to be cherished forever and admired by future generations.

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