Grandidierite Citrine Smokey Quartz Necklace
This necklace features a stone called Grandidierite, which is one of the rarest minerals on earth, predominantly mined in Madagascar. Its gorgeous, blue/green color is framed by apatite, citrine and smokey quartz gems. The Grandidierite stone measures 12mm and is suspended between a sterling silver, diamond cut, cable chain. Blue apatite beads decorate the end of the chains near its clasp. The length of the necklace is 17 1/2" adjustable up to 20". A smokey quartz bead accents the end of the extension chain.
It was discovered in 1902 by French mineralogist Alfred Lacroix, in the cliffs of Andrahomana in southern Madagascar. In honor of another French explorer, he named the gem after Alfred Grandidier, who was the first explorer to describe Madagascar in detail. With a hardness of 7.5, this blue/green stone is extremely rare due to the fact that when pockets are discovered, they are small and become depleted quickly.
