A brand-new, unused GIA-certified platinum natural diamond solitaire engagement ring, showcasing a magnificent 1.00ct marquise-cut diamond at its centre. Graded the highest D colour with SI1 clarity, this elegant stone delivers exceptional brightness, fire and a beautifully elongated silhouette that flatters the hand. Expertly set in platinum, the design offers enduring strength, sophistication and timeless appeal.

Valued at £14,500.00, this impressive solitaire represents refined craftsmanship and lasting desirability. Natural diamonds remain sought after for their rarity, authenticity and finite supply, characteristics that may support appreciation over time. Their established international demand and enduring prestige can also enhance long-term investment potential, making this engagement ring a compelling choice for both a meaningful proposal and a valuable addition to any jewellery collection.

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

This lot is accompanied by the Gemologist Report/Valuation, a Presentation box, and a gift bag.
