October Birthstones
Opal
Opal is the October birthstone as well as the accepted anniversary gemstone
for the 14th year of marriage.
White opal has a white or light body color with flashes of many colors. Black
opal has a black, dark blue, dark green or gray body color with vivid flashes
of color such as red, pink and bright green.
Opal has symbolized hope, innocence and purity through the ages.
Care should be taken to protect opal from scratches, sharp blows, household
chemicals and extreme temperature changes. To maintain the brilliance of opal,
it should be wiped clean with a soft cloth. Do not use a home ultrasonic machine
or jewelry cleaner.
Opal sources are Australia, Mexico and the United States.
Tourmaline
Sometimes tourmaline, which spans the spectrum from red to violet, is used
as a birthstone for October. Tourmaline also occurs in color combinations
in one stone, which accounts for its popularity. It is not as fragile as opal
and is sometimes selected by those who prefer faceted stones.
