Halo

A halo is the loud cousin of the hidden halo: instead of tucking the extra diamonds underneath, a halo rings the center stone completely, right where everyone can see it. The effect is a real optical trick, making the center read noticeably larger than its actual carat weight, which is why it is a genuinely popular choice, sorted here with our best-selling first.

Nearly every halo setting here is exactly that, a setting, so the center stone is chosen separately, with us, natural or lab grown. The occasional piece is the exception and arrives complete, the diamond already set. Metal runs the full range on this shelf, yellow, white, rose gold and platinum, so do not assume the one you saw first is the only option. And a setting built for an emerald center turns up here too, in case color is what you are actually after.

Every small stone in that ring takes the same daily knocks as the center it circles, so the free annual service on anything bought here goes over all of them. And if the showroom is out of reach, the text button reaches a person, not a form: describe the design and the stone, get photos back.
