Mark Smith

Mark began his gemological career in 1980 at a jewelry store in Richmond, VA. From 1982 till 1994, he was in charge of the appraisal and repair departments.

In late 1994, he jumped at an opportunity to move west and accepted a job in Portland at Carl Greve as manager of the appraisal department, and worked there until the close of the store in 2008.

After a stint at retail, he joined the Pacific Gem Lab team in 2011.
Mark is both a Graduate Gemologist (G.I.A.) and a Certified Gemologist Appraiser (AGS).
When he’s not appraising jewelry, Mark enjoys cooking and the great outdoors.
He is delightfully married with three grown children.

Jill McIntosh


Jill is a G.I.A. Graduate Gemologist. In early 2003, she began her career in gemology as a diamond grader for G.I.A. in their grading lab in Carlsbad, CA. After continuing along that path for almost 10 years, Jill sought out an opportunity to move beyond her expertise in diamonds and diamond grading into appraisals and valuations. In early 2013, she joined the team at Pacific Gem Lab where she is able to continue her education as a gemologist appraiser.
