At the center of this ring is a rare oval Paraíba tourmaline of about 2.29 carats, from Mozambique, with the bright blue-green color that makes these copper-bearing stones so sought after. A GIA Tourmaline Origin Report confirms the stone’s origin. It sits in four prongs inside a halo of round brilliant diamonds, which sets off the stone’s color. The split shank has a channel of baguette diamonds between two rows of round brilliants, so the ring catches light from every angle. It’s made in 18K white gold and is a strong choice for an engagement ring, an anniversary gift, or a collector of fine colored gemstones. The GIA report is included, and the stone is clarity enhanced, as noted on the report.
