is an ancient gem, in fact sunstones have
been discovered in Viking burial mounds. It was thought that the
sunstone aided in navigation.
Formed and crystalized in a lava flow, Sunstone is a member of
the feldspar group
of minerals and is closely related to Moonstone. These produce
two types of material, one
that is cut en-cabochon or made into beads like opal or jade and
the other is faceted like
a diamond or saphire.
The cabochon and bead material exhibits a unique visual phenomenon
known as "schiller"
which is caused by millions of microscopic copper platelets. These
copper platelets reflect
light with varying intensities depending on their concentrations.
The "schiller" phenomenon
makes the stone appear to glow even when viewed from a distance.
It has been suggested that Sunstone would be an excellent alternative
to Peridot as
the August birthstone. When set alone or in combination with other
gems, Sunstones make a
fabulous addition to any collection.
Until recently Sunstone was available only in limited quantities
and poor grade.In the early 1990's location of three different
deposits in Oregon have made it
possible for top-grade rough and cut stones to be readily available
at competitive prices.
The faceting material comes in a wide range of colors and properties,
some of them being
