About This Band

Matching marquise lab-grown diamonds run tip to tip around the whole of this slim white gold band, each lying lengthwise so the points follow the circle. Neighbouring stones share the prong at their meeting tips, which keeps the row continuous with no plain metal break. Underneath, every stone sits in an open, marquise-outlined basket with rectangular cut-outs that let light reach it from the side.

  • Lab-grown diamonds: matched marquise cuts, set all the way around
  • Total lab-grown diamond weight: 0.50, 1, 1.5 or 2 ct
  • Setting: shared prongs at the tips, open baskets below
  • Metal: white gold
  • Sizing: a full eternity band can't be resized; one free size change within 60 days of delivery means remaking the band (about 10–15 days)

Made to order in 10–15 days, with free shipping on orders over $500 and 30-day returns.

Shipping & Returns
Complimentary shipping on every order, with free 30-day returns. Each band ships fully insured in signature packaging, ready to gift.
Sizing & Resizing
A half-eternity setting leaves the underside smooth — perfect for comfort and easy resizing. Choose your US ring size at checkout; one complimentary resize is included within 30 days of delivery.
The Renaissance Promise
Every band ships with a Renaissance Jewel Certificate of Authenticity and is ethically crafted with lab-grown diamonds. Includes a free appraisal and a lifetime warranty covering cleaning and prong inspection.
