Rogers in house Gem Lab features the latest equipment, for the most reliable appraisal of your diamonds and precious gems. It is headed by a Graduate Gemologist, a title not easily attained from the GIA.

Through the use of this equipment and the knowledge of our Graduate Gemologist we are able to identify and value almost any kind of gemstone. Complete written appraisals are available. Doing a real appraisal takes some time and effort. You can be sure that anyone who gives a quick look through a jewelers loupe and writes an immediate appraisal is only making a guess at best.

  • Diamond Probe
  • Leveridge Gauge
  • Digital Scale
  • Binocular Microscope
  • 10X Loupe
  • Master Diamonds graded by the GIA Gem Laboratory
