About this ring
Antonia sets the oval center stone in claw prongs above a petal-shaped gallery, where small diamonds form a hidden halo seen from the side. Pavé runs across the top half of the thin band, leaving the lower band smooth and polished.
An oval runs along the finger, so the hand looks longer, and it tends to look larger face-up than a round of the same weight. A 1 ct oval is about 7.7 x 5.7 mm; a 2 ct, about 9.7 x 7.2 mm.
On this thin pavé band, a 1 to 2.5 ct oval keeps the proportions light; larger stones read bolder. Antonia also comes in round, emerald, princess, radiant, pear and marquise.
- Center stone: oval lab-grown diamond, IGI-certified. Choose 1–5 ct (carat = center stone only).
- Side stones: 34 lab-grown diamonds, about 0.55 ct total with a 2 ct center.
- Quality: VS1 F–G, VVS1 F–G or VVS1 D.
- Metal: solid 14K or 18K gold in yellow, white or rose.
- Made to order: ships in about 3 weeks.
Care: wash it in warm water with mild soap, take it off for the gym and heavy work, and have the pavé checked once a year.

Find her ring size
Lay a ring she already wears on a ruler. Measure straight across the middle, from inside edge to inside edge, in millimeters.
Wrap a strip of paper around the base of her ring finger, snug but able to slide over the knuckle. Mark where it overlaps and measure to the mark in millimeters.
Two easy ways to find her size at home, then match your number in the chart.
