Halo Rings | Lab Grown Diamond | VVS CVD

A halo is a ring of small diamonds set around a larger centre stone. Its purpose is optical: the halo blurs the boundary of the centre stone so the eye reads the whole cluster as one diamond, which typically makes a centre stone appear a half to a full carat larger than it is. Ronora lab grown diamonds are real CVD stones, VVS clarity, D-E-F colorless; a small number of halo rings here are set with moissanite, stated on each product page.

How much larger does a halo make a diamond look?

Roughly half a carat to a full carat in apparent size, depending on how tightly the halo sits and how large the surrounding stones are. This is why a halo is the most cost-effective way to get visual scale without paying for centre carat weight.

What is the difference between a halo and a hidden halo?

A visible halo sits on the same plane as the centre stone and is seen from above. A hidden halo sits underneath, beneath the girdle, and is only visible from the side. A hidden halo adds light and a detail worth finding without changing the ring's outline from the top.

Frequently asked questions

Is a halo harder to clean? Slightly. More stones means more settings for residue to collect in. Warm water, mild soap and a soft brush once a week keeps a halo bright.

Does a halo suit every shape? It works with all of them, but it has the strongest effect on round, oval and cushion, where the halo can follow the outline closely.
