Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of a 9 x 7 mm emerald cut diamond, casting a glassy, architectural glow that draws the eye with quiet confidence. This three-stone semi-set ring in warm 18K rose gold frames your chosen center stone with precision, its clean lines and structured silhouette embodying modern minimalism.

Handcrafted in Williamsburg, the band’s smooth finish and low-profile setting ensure comfortable daily wear, while the three-stone arrangement balances presence with subtlety. Each piece is meticulously inspected to meet exacting standards, reflecting the studio’s commitment to refined craftsmanship.

Choosing a lab-grown emerald cut diamond aligns with a sustainable ethos, offering clarity and brilliance without compromise. The rose gold’s gentle warmth complements the emerald’s cool geometry, making this ring ideal for those who appreciate architectural elegance paired with understated luxury.

Designed to sit gracefully alongside other bands or worn solo, its comfort fit and moderate width suit a variety of hand shapes and sizes. Should you need resizing or prefer a custom consultation, the studio offers personalized guidance with thoughtful care.
