Syllabus
Textbooks:
There are no
required textbooks. There are two
recommended books:
Simon and Schuster’s Guide to Gems and Precious
Stones, ed. by Kennie
Lyman
Gemology, by Cornelius S. Hurlbut, Jr. and
Robert C. Kammerling
(on reserve in the Engineering and
Physical Sciences Library (EPSL))
Course Description:
A survey of the origin, occurrences, properties, fashioning
and
treatments of natural and synthetic materials, with emphasis on
diamonds and
colored stones.
Attendance:
Examinations
will be
based largely on material presented in the class as well as the reading
assignments. If you miss a lecture, it
is your responsibility to obtain notes from a colleague.
If you are absent from any exam, quiz, or lecture
where an assignment is due, it is your responsibility to provide the
instructor
with documentation of a university-approved absence.
Upon receipt of proper documentation you will
be permitted to make up any missed work.

Exams:
There will be two midterm exams and a
comprehensive final. Exams will consist of
multiple choice,
definition, short answer and/or essay questions. You
may not use notes or any other study aids
on exams or quizzes. There are no
specially scheduled or makeup exams.
Exceptions will be made for students with disabilities or
extenuating
circumstances that have been officially recognized by the university. Arrangements must be made at least one
week in advance of the examination. The
date and time of the final exam are NOT negotiable.
I will not schedule alternative dates for the
final exam.
Pop quizzes: Pop quizzes will be held
at any time on any
day during lecture and will be based on assigned reading, material
covered in
lecture, or information collected for your gem journal (see below). Each quiz will be worth 5 points.
If you are absent from class you will receive
0 points on the quiz. You may not use
notes or any other study aids on exams or quizzes.
Late penalties: 5%
of the grade will be deducted from the assignment
(e.g. Gem Journal) for each day that it
is handed in after the due date. Exceptions will be made for documented university-approved
absences.
Field trip to
the Smithsonian National Museum of
Natural History Hall of Geology, Gems, and Minerals
At a date and time to be determined, we
shall take a tour of
the Hall of Geology, Gems and Minerals at the National Museum of
Natural
History in Washington, DC. The Smithsonian is home to the Hope Diamond,
along with other famous and beautiful gems.
Attendance and active participation in this fieldtrip will count
towards
5% of the total course grade. Students
who are unable to participate will be required to write a 5-page
(double-spaced) written report on a topic approved by the instructor.
Extra Credit:
Each class day a new gem (or gems) is
introduced, you will
have the opportunity to gain one extra credit point to count towards
midterm
exam grades. If you bring in an
interesting (and correct!) fact about the gem to the first class
discussion
about that gem, written out on paper along with the source of that
fact, I will
award an extra credit point for the fact.
There are a few catches. The
first catch is that the fact must not be found in either the Gemology
text by
Hurlbut and Kammerling or the Simon and Schuster’s Guide.
The second catch is that the fact must be
relevant to the course. The third catch
is that if more than one person brings in the same fact, the extra
credit point
will be split among the individuals (e.g. if 3 students bring in the
same fact,
each student will receive 1/3 of an extra credit point). These two catches give you the incentive to
look at sources other than the assigned textbooks, encourage you to
look for
extra credit on your own and to look for unusual or hard to find facts. You must include the source of the fact, so
that I can check its veracity.
Academic
Integrity: The
student is expected to be familiar with and follow the principles of
truth and
academic honesty outlined in the Student Honor Council’s Code of
Academic
Integrity.
The Code can be found at:
http://www.shc.umd.edu/code.html.
Gem Journal
For each
gemstone
discussed in class, you will be responsible for collecting the
following
information:
Gem name
Chemical Formula
Crystal system
Hardness
Density/Specific Gravity
Refractive index (or
indices)
Occurrence or Genesis (how does it
form? in what types of rocks is it found?)
Localities found
(not all localities, either famous gem localities or major deposits)
Appearance (includes
color(s), common crystal habits, luster, cleavage, etc.)
Distinctive features (are
there any prominent
characteristics that may be particularly useful in identifying the gem?
how is
it distinguished from other, similar gems?)
Interesting facts
The information
should be obtained before the day the gem is introduced in class. Pop quizzes will frequently be based on the
information obtained for the gem discussed on a given day.
This information should be collected in a binder,
notebook or journal that will be collected periodically and graded for
correctness and detail. You should
devote one or more pages to each gem discussed in class.
You may want to include a photo of each gem
(printed out from the internet, for example).

information include:
