Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring in 18K yellow gold offers a refined foundation, ready to cradle a 9 x 4.5 mm marquise stone with a secure yet delicate bezel setting crafted in our Williamsburg studio.

The warm glow of 18K yellow gold is hand-finished to a soft, satin polish that feels weightless against the skin. The low-profile mounting ensures everyday comfort and ease under gloves or stacked with other bands, while the slender shank balances strength with subtlety. Each ring undergoes meticulous inspection to meet exacting standards of symmetry and finish.

Our commitment to lab-grown diamonds means your center stone will shine with clarity and brilliance, created sustainably without compromise. This ethical approach aligns with the mindful craftsmanship behind every piece we design.

Ideal for those who appreciate architectural elegance paired with artisanal detail, this setting suits a hand that favors clean lines and understated drama. The marquise shape’s tapered points elongate the finger, enhancing natural grace.
