Natural iolite, also known as
"water sapphire" or "Vikings' Compass," is a gemstone that
belongs to the mineral group known as cordierite. The name "iolite"
is derived from the Greek word "ios," meaning violet, which is a
common color for this gemstone. Iolite can also exhibit shades of blue, gray,
yellow, brown, and green, depending on its orientation and the angle of light.
Key characteristics of natural
iolite include:
Color: Iolite is known for its
pleochroism, meaning it can display different colors when viewed from different
angles. Typically, it appears violet-blue in one direction, yellow-gray in
another, and nearly colorless in a third. The intensity and distribution of
these colors can vary.
Clarity: Iolite is usually
transparent to translucent. Inclusions may be present, but they do not
typically affect its overall appearance.
Cut: Gem cutters often orient
iolite to maximize its desirable blue-violet color. It is faceted in various
shapes and sizes for use in jewelry.
Hardness: Iolite has a hardness
of 7 to 7.5 on the Mohs scale, making it suitable for everyday jewelry wear.
Origin: Iolite is found in
various locations worldwide, including Brazil, India, Sri Lanka, Mozambique,
and the United States (especially in the states of Connecticut and Wyoming).
Usage: Iolite is a popular
gemstone for jewelry, including rings, earrings, pendants, and bracelets. Its
unique color and pleochroic properties make it an attractive option for those looking
for something different.
Lore and History: The Vikings are
believed to have used thin pieces of iolite as a polarizing filter to navigate
the seas. By looking through the gemstone, they could determine the exact
position of the sun on overcast days, helping them navigate safely.
Treatment: Iolite is generally
not subjected to any significant treatments. However, like many gemstones, it's
important to be aware that some stones on the market may undergo enhancements
to improve color or clarity. Always inquire about the treatment status when
purchasing gemstones.
As with any gemstone, it's
advisable to purchase iolite from reputable sources, and if possible, request
certification that provides information about its authenticity and any
treatments it may have undergone.
