A monumental 21.75-carat Paraiba tourmaline displays a remarkable intensity of color at the center of this ring. Exhibiting a desirable blue-green hue, the gem is described by the American Gemological Laboratories as "outstanding," certified as entirely natural and Mozambique in origin. Since the majority of these stones have been heat- or clarity-enhanced to achieve their hues, to find an untreated stone of this size, clarity and saturation is exceptionally rare. Set in platinum, the oval brilliant-cut gemstone is enhanced by diamonds totaling 3.50 carats.
Only first discovered in 1989, the Paraiba tourmaline is one of the world’s rarest and most vibrant gemstones, and they have only been found in the copper-rich mines of Brazil, Nigeria and Mozambique. It is thanks to their rare chemical composition that these gems owe their spectacular coloring and brilliant glow that appears to light the stone from within.Download the Certification and Appendix
