1.990 ct, a hair under two carats and the emerald cut makes the most of it. The stone is long and rectangular at 7.5 x 5.25 mm, so it covers more finger than a rounder shape of the same weight would. Prongs hold it at the corners inside a snug halo of small round lab grown diamonds that follows the outline of the rectangle. That's the Emerald Cut Twisted Shank Halo Ring in its simplest form. What keeps it from being a standard halo is the band: on each side a diamond set strand crosses over a smooth polished one, so the shoulders have movement of their own.

The 59 round diamonds in the halo and along the twist add 0.500 ct, bringing the ring to 2.490 ct in total and every stone is a lab grown diamond. That's the value case in one line: close to two and a half carats for the price of a much smaller mined ring, a gap our guide to lab grown vs mined diamonds breaks down. IGI certifies the diamonds and the ring is hallmarked. Choose solid 10K, 14K or 18K gold in yellow, white or rose. It's a natural proposal ring, and the photos show it stacked with a slim twisted pave band, which also suits an anniversary.
