Prized
through the ages as, in the words
of the Roman historian Pliny, the “gem of gems … surpassing
all other precious stones in virtue, ruby is the red variety
of the mineral corundum. Historically, it has been symbolic
of love and passion, considered to be an aid to firm friendship,
and believed to ensure beauty. Today’s birthstone for
July, ruby has a color that ranges from purliksh or bluish
red to a yellowish red. The finest color is a vivid, almost
pure spectral red with a very faint undertone of blue,
as seen in Burmese rubies, which are considered the finest
amoung ardent collectors. Other sources of fine ruty are
Thailand, Vietnam, Cambodia, Kenya, Tanzania, and Azad
Kashmir in Pakistan, and a new deposit was recently discovered
in Australia. The ruby is very brilliant and very hard,
ranking 9 on Mohs’ scale . Ruby is also very durable and
wearable-characteristics that make it an unusually fine
choice for any piece of jewelry.

The
“celestial” sapphire-symbol of
the heavens, guardian of innocence, bestower of truth
and good health, preserver of chastity-is in fact the
mineral corundum. While we know it best in its blue variety,
which is highly prized, it comes in essentially every
color; red corundum is ruby. As with ruby, its sister
stone, sapphire is characterized by hardness (9 on Mohs’
scale), brilliance, and availability in many beautiful
colors, all of which make it probably the most important
and most versatile of the gem families.
Blue sapphire can be among the most valuable members of
the sapphire family-especially stones from Burma and Kashmir,
which are closest to the pure spectral blue. Fine, brilliant,
deep blue Burmese sapphires will surely dazzle the eye
and the pocketbook, as will the Kashmir, which is a fine
velvety-toned deep blue.
