Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set halo engagement ring foundation in warm 14K yellow gold invites your choice of a 7 x 3.5 mm center stone, ready to frame brilliance with delicate artisan precision.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a low-profile setting that balances daily wearability and refined presence. The halo’s petite pavé stones are meticulously set to amplify light play, while the smooth finish ensures a gentle feel against the skin.

Each lab-grown diamond option reflects our commitment to ethical jewelry, offering clarity and sparkle without compromise. The yellow gold’s rich tone complements the marquise’s vintage-inspired geometry, ideal for those who appreciate subtle drama and architectural elegance.

Designed for a wearer who values both artistry and practicality, this ring’s slender silhouette fits comfortably beneath gloves and stacks seamlessly with other bands. Its semi-set nature allows you to select a center stone that resonates personally, creating a truly custom expression.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers expert consultation with thoughtful care. Lead times are tailored to ensure every detail meets your vision.
