Aquamarine like the emerald is beryl,
the distinguishing difference between the
two gems being one of color alone, although some gem experts claim that ancient
specimens of aquamarine show a more perfectly preserved surface polish than emeralds of the same periods.
The oldest source from whence aquamarine was obtained was India. It is possible, however, that the early supply was
augmented in a limited measure by the Siberian mines. At one time, the best gems came
from Siberia and Brazil, the latter country
supplying clear, transparent stones of fine
color in the utmost profusion. Very fine
aquamarines are also found in the United States
in Maine, Connecticut, North Carolina and
California, and even more of these gems are found in France and Ireland.
While aquamarine is rated as a semi-precious stone, its value varies widely according to the quality of the individual gem.
Pale stones may be had at small cost, but
the deep sea-green or blue-green gems often
command very substantial prices. Aquamarines are to be had in a great variety of
cuttings, but as a rule the best specimens
are brilliant-cut in front, with the obverse
side step-cut.
Aquamarine was highly prized by the
Egyptians who believed that this gem exercised a powerful influence when worn as
an amulet. It was generally engraved or
worked into the shapes of birds or animals,
and there are extant many fine and interesting specimens of such carvings by this people, some of them dating back to a period
as early as 2000 B. C.
This gem was also well known in Ancient Rome, and was the only stone which
the Roman jewelers cut with facets. Pliny
(the Roman naturalist), suspected that the
aquamarine and the emerald were the same
or of a similar nature, a fact which was
not definitely established until eighteen centuries later. Writing about 60 A. D., referring to the aquamarine, Pliny states:
“There is not a color more pleasing to the
eye than that shown by these gems which
imitate the greenness of the clear sea.’’
Later, because of Pliny’s happy description
of this stone, it received its present name.
(It seems not amiss to call attention to the
fact that in spite of Pliny’s enthusiastic appreciation of the aquamarine, he could have
been familiar only with the comparatively
inferior stones from Egypt.)
