STATE OF THE ART
The SAS2000 software system troubleshoots the fancy diamond business
The SAS2000 software system, when paired with a computer and spectrophotometer,
takes the subjectivity out of diamond grading, color determination and synthetic
detection and can be used as a selling tool.
SAS2000 includes the software and upgrades for a year as well as the
spectrophotometer. Customers provide their own personal computers. The system
costs $8,995 but pays dividends, say those who use it. "People see
the machine and the color grade charts I generate for them and are impressed
and tell others," says Corey England of Mid West Gems, Moline, IL.
These are included with an appraisal. "I rely heavily on it because
my business is by referral and by appointment only. It's really an aid in
the issues of credibility and honesty."
England credits SAS2000 with helping him to sell more than 400 carats
in diamonds a year.
Using the System
"You don't have to have sophisticated knowledge to run this,"
says Martin Haske, of Adamas Gemological Laboratories, Brookline, MA, who
developed SAS2000. The system, designed to be user-friendly, enables jewelers
to get more information from a diamond than using a spectroscope alone.
The spectrophotometer goes beyond the visible range into the near-infrared
range, where most visible range spectroscopes cannot take readings, says
With SAS2000, users can:
- Detect synthetic colored diamonds in less than a minute.
- Determine diamond color origin - vital in detecting artificial irradiation
of fancy colors - and generate reports. An audible and visual warning alert
the user if radiation spectra are detected.
- Scan for radiation damage points in diamond, which form the basis of
origin of color reports, and provide visual proof (a computer-generated
transmittance spectra) to substantiate an appraisal.
- Help you to buy smarter from suppliers. "In diamond color grading
alone, this instrument paid for itself in the first week of use from analyzing
estate diamonds in-house," says Joe Mackley, an appraiser in Knoxville,
- Help you to sell better. Consumer-oriented color reports for diamonds
in the D-Z range can be issued, showing the "why" behind the
color grade. A consumer will be able to see where his stone falls into
the transmittance spectra - a copyright feature, says Haske.
SAS2000 users will be able to gather and exchange information about fancy
colored diamonds. This will allow users to compare their grades with the
Gemological Institute of America's fancy diamond grading system, says Haske,
and correlate their own information regarding ranges and grades. GIA's parameters
and standards are not available to the trade.
In addition to its use for diamond grading, the software includes a colored
stone database collection that allows the SAS2000 users group to collect,
exchange and correlate an unlimited database of optical spectra of colored
stones. "SAS2000 provides a vehicle for the pooling of gemstone information
in an immediately usable format," says Haske. "This will eventually
be a great tool for gemstone identification by spectra."
