This fabulous faceted 3.59 cts.pear-shaped Brazilian Tourmaline is accented with .10cts of GSI1 Diamonds. The stone is set at a slight angle which gives the ring character and uniqueness. It is made in 14KY and is a size 8. MA387. Tourmaline crystals are formed in long, column-shaped formations. An Egyptian legend believes that as the crystals grew up from the earth, they encountered a rainbow and attained every color of the rainbow, giving the tourmaline gem stone a spectacular array of beauty. Tourmaline crystals are piezoelectric. When heated, the same crystal contains both a positive charge at one end and a negative charge at the other. Even when it is cut into smaller pieces, each piece still retains this unusual characteristic.
