Opals are typically a creamy-white color and are made by the rainbow-coloured inclusions that reflect the light as the gem is moved. Black opals are very rare because approx all of them are spotted in mines in the Lightning Ridge region of New South Wales in Australia. The brighter the inclusions and the darker their background color, the more valuable the stone. In 1938 in Lightning Ridge “Aurora Australis” one of the most valuable black opals of all time is was discovered. The 180-carat black opal is especially appreciated due to its intense harlequin coloration and large size. In 2005 it was valued at about $763,000 U.S.

After years of fruitless digging, Barbosa finally uncovered a tourmaline of unmatched neon blue that set the gem market aflame. For every 10,000 diamonds, only one stone is mined and is extremely rare stone.

Count Edward Charles Richard Taaffe an Austrian-Irish gemologist in the 1940s bought a box of cut stones from a jeweler in Dublin, thinking he had bought a collection of spinels. But on closer examination, he observed that one of the pale mauve gemstones was not reacting to the light rays in the same manner as the other spinels, so Richard sent it off to be analyzed. The results unveiled that he had uncovered an unknown gemstone taaffeite. The source of taaffeite was to Sri Lanka and it is also been found in China and Tanzania.
