About this ring
Helena is a low-set solitaire: the shoulders of the plain, polished band flow straight up into the head, with no break between band and setting. Claw prongs hold the princess center stone close to the finger for a clean, sleek profile.
A princess cut is square with sharp corners and plenty of sparkle, a modern alternative to a round. A 1 ct princess is about 5.5 mm per side; a 2 ct, about 7 mm.
Because it sits low on a solid plain band, a 1 to 3 ct princess keeps a clean, close-to-the-finger look. Helena also comes in round, oval, emerald, radiant, pear, marquise and cushion.
- Center stone: princess lab-grown diamond, IGI-certified. Choose 1–5 ct (carat = center stone only).
- 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 and have the prongs checked once a year.
Ring details

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.
Measure a ring she already wears
