blue color of tourmaline is known by the name indicolite. It is one of
the rarest colors in tourmaline and fine blue and bluish-green specimens
are sought after by collectors.

can range from light to dark saturated blue. Although color grading is a
judgment call, I think many tourmalines sold as blue are
misrepresented. In my opinion, an indicolite can be any shade or color
as long as blue predominates. For example, most indicolites have some
degree of green in them. (See below). I would call a blue/green stone
with dominant blue a blue tourmaline. If the green dominates, I’d call
it a green tourmaline or verdelite. Generally, blue brings more money,
which explains why some in the trade are eager to call blue/green
tourmalines indicolites even if the green predominates.
