Why is David's the best Certified Gem Lab in Orange County?

David owns the most sophisticated Independent Gemological Laboratory in Orange County.  

It features the following equipment:

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. This microscope is more advanced than 99.9% of the microscopes in use at major Gemological Labs around the country. David can use the capabilities of this microscope to accurately grade gemstones and show his clients significant features about their jewelry and gemstones under high magnification on an LCD HD screen.


HRD D-Screen Synthetic 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 this machine.  David now has two of these machines.

Nine Diamond Certified GIA Master Diamond Set
One of the largest sets owned by an Independent Gemologist in the country. Most Gemologists use CZ master sets which are unstable and doesn't show color the same way a "real" diamond master does.
