Buying guide

How a hidden halo works

A hidden halo is a ring of small lab-grown diamonds set just beneath the center stone, under its widest edge. From the top the ring reads as a clean solitaire; from the side, the hidden row adds a flash of sparkle. It suits anyone who likes a simple top view but wants some detail up close.

Choosing the center shape

Round is the brightest and most classic shape. Oval, pear and marquise are longer, so a 3 carat center looks larger and covers more of the finger. Cushion, princess and radiant give lively sparkle in square or rectangular outlines; emerald and Asscher are step cuts with a calm, mirror-like look. Heart is the boldest choice. The hidden halo follows whichever shape you pick.

Band and metal

The pave band comes in widths of 2 mm, 2.2 mm or 2.5 mm. Platinum is naturally white and hard-wearing and costs more than gold; gold comes in 10K, 14K or 18K white, yellow or rose gold. Prices start from about $1,950 in the lowest-priced metal, with the 3 carat lab-grown diamond center included.

Made to order

Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
