Rubellite is a member of the family of tourmalines, and its colour glitters in beautiful nuances in the range from red to shocking pink. Exhibiting a deep intense red colour, absent of any tinges of brown, rubellite is the most valuable of tourmalines. Rubellites of high clarity and intense colour are extremely rare and exceptional. The rubellites suspending from this diamond necklace are all of uniform colour and have no visible inclusions to the naked eye. To be able to find nine rubellites whose intense colour, shape and clarity are so well matched is a tribute to Tiffany's and their pursuit towards perfectionism and producing only the highest quality jewelry.
