Recent EducationMy most recent educational event was the AGA seminar on red diamonds—natural diamonds with induced color. Amazing, considering there are probably only 100 or so natural color red diamonds around.

I have taken and passed the ASA courses, the ISA courses and the JCRS insurance appraisal course. I have written and taught several appraisal courses for ASA, including updating the Master Gemologist Appraiser course. I have taught appraisal courses in various universities throughout the country.
Master Stone SetLazar Kaplan Ideal cut diamond grading set certified by GIA
Cut Evaluation ToolsI use an H&A scope, the Ideal-Scope, the ASET, a crown angle gauge, and a mm gauge built in to the ocular of my microscope.
Cut Info in ReportTable, Crown height, Crown %, Crown angle, Pavilion depth %, Girdle thickness and finish, Culet size and note if abraded or chipped, Brilliance on a score of Poor to Excellent, Proportion Grade (GIA scale of IA-IVB) and H&A symmetry noted if present
Other Areas Of ExpertiseI appraise vintage and period jewelry, and can discriminate between an old piece and a reproduction.
Unique ServicesDiamond Gemprints while you wait.
Appraisal document can now be provided in .PDF form, which most clients (and insurance companies) seem to prefer--or I can provide it the old-fashioned way: two printed copies.

I have a portable lab, but prefer to work in my office. For some legal cases and government agencies such as US Customs, it is necessary to go on-site, which I do at my daily rate.
PublicationsCo-auther of the manuals for the two advanced ASA courses leading to the Master Gemologist Appraiser cettification: ASA GJ205 and ASA GJ206, among other course manuals.
TurnaroundFor one item—while you wait. The turn-around time on larger jobs depends on the size of the job. Right away for small jobs, several weeks for large estates.   Clients can attend appraisal sessions

Services for Other BusinessesI rarely grade for stores—but the local jewelers pass out my business cards and recommend me to their customers. If I were ever to have a conflict of interest, I would disclose it prior to accepting the assignment.
OpinionKnow that there are many types of appraisals, and that jewelry can have a different value in one market as opposed to another.
Be an informed consumer. Remember that every color & clarity grade represents a range. A “G” color diamond could be nearly an “F” or nearly an “H” and that may be reflected in the price. Same thing with clarity.

Probably the most important part of an insurance appraisal is a detailed description of the value-making characteristics of the item. The insurer is bound by what is
* Note: There is no regulation of jewelry appraisers. Most have not invested the time or money in education and equipment to be qualified as professionals. Credentials come in many shapes and sizes. Know the difference, and check with the credentialing association

Cut Info in ReportMost diamonds I see are in the mounting, so am limited in what I can report, but I try for table and depth percentage. I am working on reporting the cut grade.
Other Areas Of ExpertiseI never report on origin. That must come from GIA, AGTA, American Gem Lab or AGS, Gublin. I stopped saying "old" European on my reports years ago. Can I tell if its a modern "old" cut. I would say yes. I only report that I am suspicious of treatment. I leave that up to the labs.

OpinionMy web site is my explanation of what I offer, what I charge, my gemology and appraisal education. There are other "appraisers" who charge similar or more then I do, but their education and continuing education usually is not equal to mine. It is important for the consumer to know this when "shopping" for an appraiser. I also try and grade to the standards as taught by GIA, not make up my own nomenclature. The appraisal methodology used, is that which is taught by the association one belongs to. If you say

Services for Other BusinessesI consult with several jewelry stores in my area, and disclose this to my clients. This does not affect my objectivity. I will not sign my name to a document that I could not defend in a court of law.
OpinionI believe that appraising is a Profession, and even though one might be a gemologist, or a retailer with many years in the jewelry business, it does not necessarily make them an effective appraiser.
I also believe that you obtain a more objective appraisal from an Independent Appraiser, no matter how honest or well-meaning the retailer.
I have been in the jewelry business for over 25 years, and have experience in several aspects, from sales to buying (from vendors as well as the public). This is an exc

Services for Other BusinessesI am an independant appraiser that sets up at independat jewelry stores for appraisal promotion days. The client can stay in the store and wait for their appraisal.
OpinionA jewelry appraisal is largely a matter of research, you are the source for sales records of personal property such as jewelry. If you withhold documents at the beginning of an appraisal, then produce them for consideration after the appraisal is complete, the appraiser has every right to charge you for the extra time it will take to re-check his original estimates. You will not benefit in the end by playing "mind games" with your appraiser.
* Note: I travel out of state all expenses paid by client plus a daily rate. I work by appointment only, payment cash or check.
