A brand-new, unused natural diamond three-stone eternity ring of bold proportion and refined balance, set with three impressive brilliant-cut diamonds with a combined weight of 2.40ct. Each stone is GIA-certified and graded H for colour, with SI2 clarity, delivering intense brightness, lively fire, and an attractive face-up appearance that creates immediate visual impact. The three-stone arrangement creates a powerful, symmetrical presence across the finger, offering timeless appeal rooted in classic fine jewellery design.

The ring is crafted entirely in platinum, a precious metal selected for its rarity, strength, and naturally white tone. Platinum provides exceptional durability and long-term security, ensuring the diamonds remain firmly set while maintaining the ring’s structure over decades of wear. This example remains completely unused, retaining crisp detailing, clean lines, and a confident, well-weighted profile.

Natural diamonds continue to demonstrate long-term appreciation, supported by finite global supply, increasing mining constraints, and sustained international demand. Larger total carat weights in certified natural diamonds are increasingly challenging to replace, strengthening their position as tangible assets. Beyond its symbolic meaning, this ring offers genuine investment potential, combining intrinsic material value with enduring desirability, market resilience, and confidence in the global fine jewellery landscape for discerning collectors worldwide.

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