A 5.17-carat cabochon Paraiba tourmaline displays a remarkable intensity of color at the center of this ring by the celebrated Oscar Heyman. Its electric blue color is certified by the Gübelin Gemlab as being natural and Brazilian in origin. Set in a classic platinum setting, the oval gemstone is complemented by diamonds totaling 2.63 carats.
Only first discovered in 1989, the Paraiba tourmaline is one of the world’s rarest and most vibrant gemstones. Considered even rarer than diamonds, these extraordinary stones have only been found in the copper-rich mines of Brazil. Paraibas also hail from mines in Nigeria and Mozambique, however, these stones possess no copper, making Brazilian examples more vibrant and desirable. It is thanks to their rare chemical composition that these gems owe their spectacular coloring and neon-bright glow that appears to light the stone from within.Download the Certification
