Thick band engagement rings
Chunky engagement rings on our 3mm band, the widest we make in gold or platinum, so the band carries as much of the look as the stone. Every ring opens at 3mm, and you can choose 2.5mm or 2mm before you order.

How wide is a 3mm band?
3mm is the widest band we make, half as wide again as our standard 2mm, and at that width the band stops framing the stone and becomes part of the look. It carries the most metal of any width, holds its shape through decades of daily wear, and balances a centre stone of 2 carats or more.
