Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the hand with quiet elegance. This semi-set solitaire invites you to choose a center stone that balances bold geometry with a whisper of vintage romance.

Crafted in 18K white gold, the mounting’s slender prongs cradle the marquise shape securely while maintaining a refined, low-profile presence. The band’s smooth finish and subtle taper ensure a comfortable fit, designed for everyday wear without sacrificing grace.

Each piece begins in our Williamsburg studio, where expert hands shape and polish every curve before a final inspection ensures flawless craftsmanship. The choice of a lab-grown diamond center reflects a commitment to ethical jewelry, offering clarity and brilliance with a smaller environmental footprint.

This solitaire suits those who appreciate a statement ring that remains understated in its comfort and form. Its narrow width and low setting make it ideal for stacking or wearing solo, complementing slender fingers or elongating shorter ones with its distinctive shape.

Should you wish to adjust sizing or explore custom details, our Brooklyn studio offers a pressure-free consultation to guide your design journey.
