Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender, dramatic sparkle that dances with every movement. This three-stone engagement ring pairs a 12 x 6 mm marquise center with two delicately tapered side stones, all set in warm 14K yellow gold that feels substantial yet refined on the finger.

Each gem is securely nestled in a handcrafted setting, polished to a satin finish that softens the gleam for everyday wear. The low-profile design ensures comfort beneath gloves or alongside stackable bands, while the gently rounded shank offers a balanced hand feel without excess bulk.

Our commitment to sustainability shines through the lab-grown diamonds, which deliver exceptional clarity and brilliance with a smaller environmental footprint. This ring’s silhouette flatters longer fingers and adds a touch of vintage-inspired elegance without sacrificing modern wearability.

Sized to order in Williamsburg, the ring can be adjusted with care to maintain its structural integrity. Whether worn daily or reserved for special moments, it embodies a quiet confidence and artisanal precision.
