Madagascar Green Sillimanite
Sillimanite is named for one of the first American professors of science, Benjamin Silliman, who taught chemistry and geology at Yale University during the early 1800s. This gem radiates transparent pale slate blue with green or violet undertones.
Sillimanite, one of the most difficult gemstones to fashion, is normally fibrous in wavy bundles and can have a wide range of hardness within a single stone. These characteristics make sillimanite a tricky treasure to cut. It exposes a faultless cleavage in one direction, a feature it shares with diamonds. This challenge puts a premium on shaping the gem, which is a significant consideration in determining quality.
One of the rarest gemstones, it is not common to find sillimanite in a local jewelry stores. It is mostly a collector's find. However, jewelry designers are beginning to adopt this aluminum silicate gem into their body of work.
