The Gem Lab I.C.G.A.  an Independent American Gem Society Accredited Gem Laboratory


Normal business hours are 10 a.m. to 6 p.m. Monday through Friday, but because “normal” hours seldom happen; always call before you drop by since we work away from the office regularly. We are happy to set up an appointment at pretty much any time that is convenient for you including weekends, early mornings or evenings.

Phone: 479-444-7759 or email to set up a time.
