Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that seems to dance with every movement. This semi-set halo ring foundation in warm 14K yellow gold frames a 12 x 6 mm marquise center stone, designed to amplify its tapered drama and graceful presence.

Expertly crafted in our Williamsburg studio, the band features a low-profile setting that balances elegance with everyday wearability. The halo setting, ready to embrace your chosen center, enhances brilliance while maintaining a comfortable fit that slips easily beneath gloves or alongside stackable bands.

Each piece reflects our commitment to ethical jewelry, showcasing lab-grown diamonds that offer clarity and sustainability without compromise. The warm gold tones complement the marquise’s vintage-inspired shape, making it a refined choice for those who appreciate subtle romance and architectural beauty.
