Aviva Diamond Marquise Halo Engagement Ring 18K White Gold 12.00ct

Aviva, the exquisitely composed 12.00 carat total weight Diamond Marquise Halo Engagement Ring in 18K white gold, is a luminous celebration of elongated elegance, vintage romance, and refined sparkle. A captivating marquise-cut centre diamond is framed by a delicate halo of round brilliant diamonds and set on a polished white gold band, creating a design that feels both dramatically slender and luxuriously radiant. Worn alone as a striking statement or paired with a slim diamond wedding band, Aviva offers a light-filled, unforgettable expression of enduring love.

The marquise-cut diamond, with its pointed ends and gently curving sides, lengthens the appearance of the finger while releasing a continuous ribbon of brilliance from tip to tip. The surrounding halo closely follows its graceful outline, amplifying presence, intensifying brightness, and forming a luminous frame that draws the eye from every angle. The cool, mirrored sheen of 18K white gold enhances the clarity and scintillation of each diamond, lending the ring a high-jewellery finish that is elegant yet effortlessly wearable. Ideal for those seeking an engagement ring with vintage-inspired lines, halo drama, and classic-meets-modern charm, Aviva is a captivating choice with timeless allure.
