Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise shape, casting a subtle, tapered brilliance that draws the eye along the finger’s natural line. This semi-set platinum mounting awaits your choice of an 8 x 4 mm marquise diamond, designed with a low-profile bezel setting that keeps the silhouette sleek and secure for everyday wear.

Crafted in Williamsburg, the band’s smooth comfort fit and sturdy platinum frame balance refined elegance with practical durability. The setting’s minimal height ensures it slips easily beneath gloves or stacks seamlessly with complementary bands, making it a versatile foundation for a lifetime of styling.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and sparkle without compromise. The semi-set design invites personal selection, allowing you to pair the mounting with a stone that resonates uniquely.

Ideal for those who appreciate architectural grace and understated strength, this mounting suits slender to medium finger shapes, enhancing the hand’s natural length without overwhelming it. Resizing is available to ensure a precise, comfortable fit.
