Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a hand, where a marquise diamond’s tapered points catch light with a quiet, refined drama. This semi-set halo engagement ring in 10K white gold frames a 9 x 4.5 mm marquise center stone, designed to amplify its distinctive brilliance while maintaining a low profile for everyday grace.

Crafted with precision in Williamsburg, the setting balances secure prongs and a delicate halo that enhances sparkle without bulk. The band’s smooth finish and moderate width ensure comfort beneath gloves or alongside stackable rings, making it a versatile choice for daily wear. Each piece undergoes meticulous inspection to meet exacting standards of fit and finish.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and sustainability without compromise. This ring suits those who appreciate architectural elegance paired with practical design—ideal for hands that favor elongated shapes and a subtle yet confident statement.

Should you need resizing or prefer a custom stone, our studio offers tailored adjustments with care and transparency. Typical lead times reflect our handcrafted approach, ensuring each ring is made to last.
