Buying guide
A hidden halo is a ring of small lab-grown diamonds set just beneath the center stone, under its widest edge. From the top, this 3 carat oval lab-grown diamond ring with hidden halo reads as a clean solitaire; from the side, the hidden row adds a flash of sparkle. The setting sits a little lower than a full halo, so it catches less on clothing.
An oval has brilliant facets like a round, so it sparkles strongly, and its longer outline covers more of the finger. A 3 carat oval looks larger than a round of the same weight and makes the hand look slimmer. Ovals can show a darker bow-tie shape across the middle; a well-cut stone keeps it faint.
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 oval lab-grown diamond center included.
