It is good to hear from you after so many years. Thank you for
your kind words about my book and I am happy that everything goes
well with you. Before, we discuss the emerald case, it may be
worth for you check my webpage at http://www.ganoksin.com/gemlab
and read my Report #4 on the “Emerald Oiling”.
I have not read the court transcript, but I know about a bit
about the case. Here is some of my thoughts:
In my opinion, nobody can tell when, where, and by whom the
emerald was infilled with some filler substance.
In my opinion, nobody can determine the precise nature of the
filler using classical gemological instruments, unless chemical
analysis would be performed and scientifically proven. Although
Opticon is used worldwide for many years, its presence in the
emerald must be scientifically proven. Otherwise, it is a
circumstantial assumption combined with good-luck.
Fillers may be mixed each other before introduction into the
emerald. After some time (nobody can tell when), the appearance
of these “oiled” emeralds alter, sometimes considerably,
especially when a) the fillers are not completely chemically
compatible and b) influenced by the environmental conditions
(heat, light, humidity, etc.).
To best of my knowledge, fillers dissociate sooner or later,
thus the emerald treatment is not permanent. However, last month,
I read in the press that some treaters have succeeded in
producing stable and permanent emerald filler. This is a separate
issue and it does not pertain to Fred’s case.
In my opinion, the State Farm Insurance won a circumstantial
case. Based on the verdict of this case, all USA gemlabs are now
exposed an subject to similar lawsuits, as well as all gem
appraisers (like Ms.Steinberg in the Ward case) no matter how
many disclaimer notices will be conspicuously placed.
Perhaps the GIA, AGTA and other related non-profit associations
shall devise policies to protect the gemologist, appraiser,
jeweler and everybody in the industry from similar lawsuits.
Imagine, your customer -to whom you sold an emerald- returning
to your shop after 3-4 years and demand refund, because the oil
dried-out and now the emerald looks “cracked” or undesirable?
