Lab-Grown Diamond Engagement Ring
Soft light filters through a 7 x 7 mm cushion-shaped diamond, its gentle facets catching the eye with a subtle vintage glow. This semi-set platinum mounting awaits your choice of center stone, crafted with artisan precision in our Williamsburg studio.
The band’s smooth platinum surface is hand-finished to a satiny sheen, offering a cool, substantial feel on the finger. Its low-profile setting balances presence with everyday comfort, designed to slip easily beneath gloves or stack alongside other bands without catching.
Each piece reflects our commitment to ethical jewelry, featuring a setting ready to showcase a lab-grown diamond—clear, sustainable, and responsibly created.
Ideal for those who appreciate understated elegance and the tactile reassurance of a comfort fit, this mounting complements the cushion’s soft, rounded edges, enhancing its vintage-inspired charm.
Should you wish to adjust the fit, resizing is available with care to preserve the band’s flawless finish. Typical lead times ensure your custom ring is crafted with deliberate attention.
