Product Description

Round Solitaire Ultra Thin Band Engagement Ring

A round brilliant Lab-Grown Diamond held by four prongs above a 1.5mm plain band. No pavé, no halo, nothing else — the classic argument, made as directly as it can be made.

What you are getting

A 0.33ct round brilliant Lab-Grown Diamond, VS clarity and F–G colour, four-prong set on a 1.5mm ultra-thin plain band. Solid 14K yellow, white or rose gold. Stones under one carat are not sold with a lab report, so this one arrives uncertified — I select it face-up at the bench instead.

Why the round still wins

Fifty-eight facets arranged over a century of refinement to return as much light as possible. Nothing else scatters light as evenly, which is why it suits a plain thin band better than any other cut: there is no pavé to add sparkle, so the stone has to supply all of it on its own.

The trade-off on a 1.5mm shank

Less metal means less resistance to bending over years of hard wear. That is true of every thin band, mine included. I do not go below 1.5mm because past that the structure stops being reliable, and if your work is hard on your hands I will gauge the shank heavier where it counts.
