Mettler
Cavat
Balance
JEWELLERS LTD.
ESTABLISHED 1950
Carat balances are often used under widely
differing conditions, Still, every weighing has
to be accurate, fast and easy to carry out.
Every model in the Mettler carat balance,
assortment is capable of meeting all these
• requirements. There is a suitable carat balance
for every weighing job - a Mettler of course.
The model C40C, for example, has an optical
range from 0 to 10 carats and indicares the
weight of precious stones with a readability
of 'boo carat. It is the "portable" Mettler carat
balance that does not depend on externa
. power supply sources and can thus be used
, anytime and anywhere

Unless they have taken advantage of the essential
gemological knowledge, few jewelers have all of the
vital knowledge, skills and techniques necessary to be
recognized as professionals. The GM home-study cour-
ses were prepared to provide the specialized
knowledge needed , by jewelers. GIA gem authorities
review all course material frequently, to be sure that it
Is as timely, up-to-date and easy to understand as
possible.
The first and foremost activity of the institute Is
training in the identification, grading and appraising of
gemstones.

Successful completion of the DIAMOND COURSE,

CERTIFICATE amcompletion of the COLORED STONE
COURSE, with its written examination, and the GEM
IDENTIFICATION COURSE, with its stone identification
practice and stone identification examination, which
requires a 100* grade to pass.
Graduates, which number more then 2500, are to be
found In many countries throughout the world. Many
more thousands have completed successfully the cour-
ses In which they enrolled.
Although gemology is offered in night classes and by
other forms of training In other countries, no other
organization of this kind and magnitude exists
elsewhere. Many universities and colleges offer cour-
ses in mineralogy and geology that lead to a degree,
but no educational source other than GI& offers the
comprehensive, specialized gemological knowledge
required by a jeweler.
