Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it creates a striking interplay of brilliance and shadow, drawing the eye along its tapered points. This semi-set halo engagement ring in 10K white gold offers a refined foundation, ready to showcase a 9 x 4.5 mm marquise center stone with secure prongs that keep the profile low and unobtrusive.

Crafted in Williamsburg, the band is polished to a smooth finish that feels balanced and comfortable for everyday wear. The halo setting enhances the diamond’s lengthening effect while maintaining a subtle presence beneath gloves or layered with other bands. Its design prioritizes durability and ease, ideal for a hand that moves through daily life without fuss.

Each piece reflects a commitment to ethical sourcing, featuring lab-grown diamonds that reduce environmental impact without compromising on clarity or fire. The semi-set format invites you to select a center stone that resonates personally, ensuring a bespoke expression of your story.

Sized to accommodate resizing, this ring adapts gracefully to your unique fit. Whether worn solo or stacked, its streamlined silhouette complements a variety of styles and hand shapes.
