Comment: Very big tourmalines are either super long (stick-shaped) or they tend to get very dark. Maintaining its color over 10 carats is a rare feat in blue-green tourmalines. This 18 carats jumbo does the trick as the images show; it is not a screaming Paraiba shade but an earthly mild teal, a green with a good splash of blue. The latter mixed 100% well distributed into the green with not the slightest hint of any color zoning. No black-out even in low light. Inclusions only under the lens and considering its size, very few as the close-up shows. Collector value gem, pendant, or ultra-massive gent's ring in no less than size twelve. Comes home to you free of charge per UPS, DSEF certified, well cut, unheated, eye-clean and with a 1000 sqm of rainforest preserved for our grandkids. Or allow me the pleasure to design a unique piece of jewelry for you. At mere $600/ct practically free of charge, although, true, it does add up over 18 carats.
