The Methods by which They Are

In q lecture on precious stones re-
Gently delivered before the Industrial.
association Of Berlin, DR.. Emmanuel
Fried edlaender said that the testing Of
diamonds Is comparatively simple. The:
common test for hardness suffices., If
the stone resists strong attacks, it is
certain to be genuine; If 1t does not,
the damage is insignificant, as only an
Imitation has, been destroyed. This
test, however, is doubtful with rubies.
# a ruby can be affected by a steel
file or by quartz, it is surely not gen
uine, but such q test with a topaz is
liable to injure valuable stone. s:
The test for hardness is Of no avail
with emeralds, as this stone is not
much harder than quartz and in addi-
tion possesses the quality Of cracking
easily. sSs = :,5 J, ..*s.4 r. ,.s,-gs
Tor examining rubies and emeralds
the optical test is best. A glass mag
nifying about 100 times suffices. Ev-
cry expert knows that. almostaall pre-
cious stones have little flaws. Nearly
every ruby and all emeralds have
many defects, which are so character
istic that the genuineness of the stones
is readily established. Such b test is
very necessary with rubies, because
the, limitations are very deceiving.
Their color is absolutely durable and
often much finer than that of the gem
uine, although it may be stated thata
somewhat yellowish tint is always sus-
picious. @.., f I'LL. IS
The only reliable way in which gen.
uine rubies can be told from limitations
is by the minute all, bubbles Of the lat
ter, which become clearly visible un-
der the magnifying glass. These are
not to be found in the natural gem.
On the other hand, the limitations lacl
certain defects characteristic Of gen.
uine rubies-certa1n yacuums, whose
outlines are much more indistinct than
those of the air bubbles in limitations.
True emeralds have similar charac-
teristic defects, such as: Enclosures Of
liquids and curious dendrites. Sap
phires also show peculiar netlike for
