A brand-new, unused GIA-certified natural diamond solitaire engagement ring, crafted in platinum and presented in pristine condition. The centre stone is an oval-cut natural diamond weighing exactly 1.00 carat, graded D for colour and SI1 for clarity, offering exceptional brightness, crisp definition, and an elegant elongated profile. Encircling the centre diamond is a refined double halo of brilliant-cut natural diamonds, which continues seamlessly along the shoulders, enhancing finger coverage and light performance. The surrounding diamonds have a substantial combined weight of 0.77 carats, creating a striking yet balanced presentation.

Natural diamonds have consistently demonstrated strong long-term appreciation, driven by their finite supply, irreversible formation, and enduring global demand. As naturally occurring assets formed over billions of years, they possess inherent rarity and provenance that laboratory-grown alternatives cannot replicate. GIA certification further reinforces confidence by verifying authenticity and grading, supporting long-term desirability and resilience within the secondary market.

Set in platinum, prized for its purity, density, and durability, this ring offers lasting confidence and understated luxury. The combination of a high-colour oval diamond, significant diamond content, and a timeless double halo design positions this piece as both a refined symbol of commitment and a considered acquisition. It represents enduring beauty alongside genuine investment potential, appealing to discerning buyers seeking permanence, stability, and long-term value across generations.

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