Auction Details

Tourmalines are the only gemstones that occur in all colors and for a long time has been called by mineral collectors as the “Rainbow Gem”. These stones are also known to attract dust when displayed under hot lights. Together with quartz, they will develop an electrical charge when heated. Tourmaline is also the only gemstone that has three sided prisms in its crystal structure.
Toughness of a gemstone may be defined as the ability to resist chipping. Jade is the toughest gemstone in nature. What makes Jade the toughest gemstone is due to its strong, interlocking fiber crystal. It may be fashioned or cut into statues or other figures and even axe heads with ease, but it’s resistance to chipping is intensely high. Early hammers and tools have been found which were formed from this gem mineral. Since the toughest gemstone is jade, it is also the most difficult to polish and carve. It requires highly trained workmanship as well as creative aesthetics to create a piece of fine jade jewelry.
