Lab-Grown Diamond Engagement Ring
Sunlight catches the softly rounded corners of a 6 x 6 mm cushion diamond, its gentle glow inviting a closer look. This semi-set platinum band awaits your choice of center stone, designed to showcase the cushion’s vintage-inspired warmth with a modern edge.
Handcrafted in our Williamsburg studio, the band features delicate accent settings that cradle the future diamond with precision. The platinum’s cool, weighty feel balances comfort and durability, while the low-profile mounting ensures everyday wearability without catching or lifting.
Each piece reflects our commitment to ethical jewelry, crafted exclusively for lab-grown diamonds that offer clarity and brilliance with a smaller environmental footprint.
Ideal for those who appreciate a subtle statement, this setting complements a range of hand sizes and suits stacking with other bands or wearing solo. Its refined silhouette fits comfortably beneath gloves or sleeves, making it a versatile choice for daily life.
Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio provides thoughtful adjustments with care and expertise.
