Find your ring size

Three ways to get there. If you already own a ring that fits the right finger, the on-screen gauge is the most accurate.

Step 1 — Calibrate your screen Match the outline to a real bank card

Hold any credit, debit or ID card against the screen and drag until the widths line up exactly. Every card in the world is the same size, so this makes the measurements below true to life.

85.60 mm

Step 2 — Match your ring Place the ring over the circle

Rest the ring flat on the screen and resize the circle until it sits just inside the band, touching but not hidden.

Inside diameter and circumference are the actual measurements of the band. Australian sizes follow the UK letter system.

US / Canada	UK / AU	EU	Inside Ø	Circumference

Measure warm

Fingers shrink in the cold. Measure at the end of the day, at room temperature, for the size you will actually wear.

Wide bands run tight

Anything above 6 mm wide sits closer to the skin. Go up half a size for comfort.

Between two sizes

Choose the larger one. A ring has to pass the knuckle, and a slightly loose band can be sized down more easily than a tight one can be opened.

Still unsure

Email your measurements and we will confirm before the piece goes into production. Every Luzora ring is made to order.

3.50 CT Round Solitaire Lab Grown Diamond Engagement Ring

Description

Three and a half carats, held in an open scroll of metal.

A 9.70 mm round brilliant lab grown diamond — 3.50 carats — sits raised in a prong setting above a sculpted openwork gallery. Two small round diamonds are set into the scrollwork on each side, so light passes right through the shoulders instead of stopping at solid metal. It's a serious center stone on a band that stays graceful rather than heavy.

Why you'll love it:

Exquisite Craftsmanship: A prong-set 3.50 CT round center lifted over a hand-finished openwork gallery, with four round accent diamonds set into the scrolled shoulders.

Premium Materials: Available in solid 925 silver, 10K, 14K and 18K gold (yellow, white or rose) and platinum to match your unique style.

Timeless Design: A classic solitaire silhouette at statement scale — 9.72 mm across the head, on a substantial 3.96 mm band.

Perfect Gift: An ideal choice for proposals, anniversaries, or celebrating a milestone moment.

Grown, cut and set in-house: we grow our own diamonds, polish them and manufacture the jewelry ourselves — no middlemen between the reactor and your finger, which is why a certified 3.50 carat center stone is priced the way it is here.
