Image Description
Tourmaline, faceted brownish pink vintage oval that was cut in1979 and acquired by Joel in Teofilo Otoni, Brazil on a buying trip. It measures 13.0 x 10.3 x 6.8 mm and weighs 6.56 carats. The beautiful eye-clean gem is extremely unusual in displaying both brownish and pink colors in different parts of the stone. Its rare and distinctive coloration would make this stone ideal for the focal element in a unique piece of jewelry. Tourmaline is a family name, consisting of more than a dozen minerals of widely varying composition. Several of these occur in gem quality, and the complex chemistry of the material results in an enormous range of colors with perhaps more than 100 distinct hues on record. Of these, green is the best known and most popular. Blue tourmaline is called indicolite, and the red variety is called rubellite. Chromium in a tourmaline creates a hue that is remarkably like that of the very finest emerald. Chrome tourmaline is quite rare, and commercially produced only in a few small African localities in Kenya and Tanzania. ?One of the photographs shows several of the books Joel has written. The Color Encyclopedia of Gemstones has for more than 30 years been the world's most authoritative source of information on (and pictures of) gemstones, including many of the rare gems. (books not included in purchase!)? The price is for this one vintage tourmaline that Joel acquired in Brazil in the1970s. *****The shipping cost includes insurance within the U.S. and internationally***
Approximate Price/Value: $660
