Grandidierite is magnesium aluminum borosilicate and one of the world's rarest gems. Specimens of grandidierite are rare even in mineral collections and museums. The name, grandidierite was bestowed to the mineral in honor of Alfred Grandidier, a French explorer and geographer who thrice traversed the island of Madagaskar; the place where grandidierite was first discovered in 1902 by French mineralogist, Alfred Lacroix. The beautiful greenish-blue color of grandidierite comes from the presence of iron. Transparent grandidierite specimens were pretty much unheard of until the last few years, when a new deposit was discovered in Southern Madagascar and some excitement was generated by a mere 0.29-carat faceted grandidierite gemstone from Sri Lanka. In recent years, an extremely limited number of larger Grandidierite gemstones have entered the market, which judging by the past century will likely be the only stones available for a long while.
Grandidierite is a fairly uncommon stone with excellent metaphysical properties that assist the growth of family unity.
The meaning of stones like these is associated with its action to stimulate improved communication ability.
