Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances across the skin. This semi-set solitaire invites you to choose a center stone that measures 12 by 6 millimeters—its tapered points lending a graceful, almost poetic drama to the hand.

Crafted in warm 14K rose gold, the band is shaped for comfort and daily wear, its gentle curve embracing the finger without interruption. The low-profile setting balances presence with subtlety, allowing the diamond’s unique shape to take center stage while remaining glove-friendly and stackable with other bands.

Each piece reflects a commitment to sustainability through lab-grown clarity, offering an ethical alternative without compromising brilliance or character. The rose gold’s soft blush tone complements the marquise’s vintage-inspired elegance, making it a fitting choice for those who appreciate refined craftsmanship and thoughtful design.

Designed for a wearer who values both romance and practicality, this mounting suits slender to medium finger sizes, enhancing the hand’s natural lines. Resizing is available to ensure a seamless fit, and the studio’s careful finishing process guarantees a smooth, polished surface that feels as good as it looks.
