Get the Most Accurate Appraisal For Selling Your Jewelry
Thermo Scientific Niton DXL Advanced XRF Gold Tester
David now has the Thermo Scientific Niton DXL Advanced XRF Gold Tester, which gives the exact gold content of your jewelry without damaging it. Nearly every gold buyer uses the inexpensive $50 “scratch acid test”, meaning they damage your jewelry by scraping it or filing it down to test it with acid, which gives only a rough approximation of the gold content. The $16,750 Niton DXL Advanced XRF Gold Tester provides a digital readout of the exact gold content of your jewelry in seconds without even touching it, and you get to see the results for yourself while watching your jewelry the whole time through the window on the device. The Thermo Scientific Niton DXL Advanced XRF Gold Tester is the most accurate gold testing device available.
Leica MZ9.5 Research Stereomicroscope, mounted with the Leica DFC290 Digital Imaging System
Allows for simultaneous direct viewing of the microscope at high resolution through the computer so that the customer can see the inside of their gemstones with their own eyes. This microscope is more advanced than 99.9% of the microscopes in use at major Gemological Labs around the country. David uses the capabilities of this microscope to more accurately grade gemstones and show his clients significant features about their jewelry and gemstones under high magnification on an LCD HD screen.
GIA iD100 Gem Testing Device with the Pink Diamond Software Upgrade
Lab Grown diamonds or "synthetic" diamonds have become more widely available in the past few years, and consumers risk the possibility of buying synthetic diamonds without their knowledge. Synthetic diamonds are dramatically cheaper than naturally mined diamonds, and the possibility of significant financial loss to a consumer who acquires a Lab Grown or Synthetic diamond in place of a naturally mined diamond is very real today. The iD100 is the best synthetic diamond tester available today, and it can test colorless to near colorless, blue, green, brown, and pink diamonds. This device can test the smallest diamonds used in jewelry all the way up the largest diamonds in a matter of seconds without even touching the stone. Very few gemologists and jewelry buyers have this extremely important piece of equipment.
HRD D-Screen Lab Grown Diamond Tester
Standard thermal conductivity "diamond testers" used by nearly every jewelry appraiser and gemologist do not work on synthetic diamonds. The HRD D-Screen is the one of the few commercially available machines that can detect HPHT/CVD synthetic diamonds and color treated diamonds. Very few gemologists have this extremely important piece of equipment. David has detected several synthetic diamonds that were appraised as "real" by other gemologists.
Sarin DiaScan S15+ with the GIA® Facetware™ Cut Grading License
This Optical Computer does the cut grading and measuring of diamonds to the highest accuracy. In addition, David has the Sarin Professional Edition Software with Photorealistic Computer Viewer, GIA® Recut Software, and Hearts & Arrows Computer Viewer.
Sarin Colibri Computerized Diamond Colorimeter
This machine grades the color of loose and mounted diamonds with computer accuracy to 100th of a single grade. This is the latest generation colorimeter, and David was one of the first Gemologists in the United States to acquire one of these machines, and now he owns two of them for making comparisons and improving diamond color grading accuracy.

Nine Diamond Certified GIA Master Diamond Set
One of the largest GIA Certified Master Diamond Sets owned by an Independent Gemologist Lab. Most all Gemologist Labs use CZ (cubic zirconia) master sets which are unstable and don't show color the same way a "real" diamond master does. Most diamond master sets also only contain 4 to 5 diamonds, but a large range 9 diamond master set like this one increases the accuracy of diamond color grading, which in turn increases the accuracy of the appraisal value.
