Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set halo engagement ring in platinum offers a refined foundation, ready to showcase a 9 x 4.5 mm marquise center with architectural grace.

Crafted in solid platinum, the mounting balances durability with a low-profile silhouette designed for everyday wear. The halo setting enhances brilliance without adding bulk, while the smooth band ensures comfort fit and ease beneath gloves or rings stacked alongside.

Each piece reflects a commitment to ethical jewelry: the marquise diamond you select will be lab-grown, offering clarity and sparkle with a smaller environmental footprint. This ring suits those who appreciate a sleek, modern shape that elongates the hand and pairs well with minimalist or statement styles.

Resizing is straightforward within our Williamsburg studio, where every ring undergoes meticulous inspection and finishing to meet exacting standards. Whether you visit us in person or design online, this semi-set halo invites a personal touch to complete your vision.
