Buying guide

The round center in a halo

A round brilliant is cut to return the most light of any shape, which makes it the brightest choice for a center. Its even outline suits a halo well, and the frame of small stones makes the round look wider from above. The halo of small lab-grown diamonds around the center adds a bright outline and makes the 3 carat stone look larger from the top.

Vintage details and a three-row pave band

Filigree, the fine openwork in the metal, gives this ring its vintage look. The band carries three rows of small pave-set lab-grown diamonds, so sparkle runs from the halo down the shoulders. The band comes in widths of 2 mm or 2.2 mm; the wider option feels a little sturdier under three rows of stones. The pave accents come in addition to the 3 carat center stone.

Metal and price

Platinum is naturally white, dense and hard-wearing, and it costs more than gold. Gold comes in 10K, 14K or 18K white, yellow or rose gold; higher karats hold more pure gold and look richer in color, while 10K is the hardest and lowest priced. Prices start from about $3,950 in the lowest-priced metal, with the 3 carat lab-grown diamond center included.
