Lab-Grown Diamond Engagement Ring

Soft light spills across a gently rounded cushion diamond, its facets catching the eye with a subtle vintage glow. This semi-set platinum band awaits a 6 x 6 mm center stone, designed to cradle the gem with artisan precision.

Crafted in Williamsburg’s studio, the platinum band features delicate accent settings that enhance the cushion shape’s soft geometry without overpowering it. The low-profile mounting ensures daily comfort and ease beneath gloves or stacked alongside other bands.

Each piece reflects a commitment to sustainability through lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

Ideal for those who appreciate a balance of classic warmth and modern craftsmanship, this setting suits a range of hand sizes and styles, inviting personalization with your chosen cushion diamond.

Resizing is handled expertly in-studio, ensuring a seamless fit without compromising the setting’s integrity.
