Half eternity or full circle
Most bands here are half eternity, carrying lab-grown diamonds across their top with smooth platinum underneath, which keeps the inside comfortable beside neighboring fingers. A few full eternity designs run stones all the way around; on those, any size change means remaking that band from scratch.
Straight or curved beside your ring
- Straight: sits flush beside a low solitaire or bezel ring.
- Curved: dips around a raised center or halo, closing any gap.
- Vintage, milgrain: beaded rims for an antique-style pairing.
Picking a carat weight
Most designs offer 0.25 to 1 carat total weight. Lighter choices make a fine thread of light; heavier ones use bigger lab-grown diamonds and look bolder against an engagement ring. Round stones lead, with princess and marquise rows on a few designs.
Platinum over years of wear
A platinum band gradually takes on a soft matte patina and can be polished back to high shine anytime. Wash its stone row with mild suds and a soft brush, and give it a separate pouch, away from harder pieces that could rub it.
