Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 9 x 9 mm cushion diamond, casting a gentle glow that feels like a quiet promise. This semi-set solitaire ring invites you to select a center stone that balances vintage warmth with modern clarity.

Crafted from 18K white gold, the mounting offers a delicate yet secure frame, its subtle curves designed to sit low on the finger for everyday comfort. The band’s smooth finish and refined profile make it an ideal canvas for a diamond that speaks to personal style without distraction.

Each piece reflects a commitment to sustainability, featuring lab-grown diamonds that mirror the brilliance of mined stones with a lighter environmental footprint.

Its understated elegance suits those who appreciate a ring that feels as natural in a morning coffee shop as it does at a weekend gallery opening. The low-profile setting pairs well with slender or medium-width bands, making it a graceful choice for stacking or solo wear.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a seamless fit without compromising the ring’s integrity.
