BUSINESS PROFILE

Bob Griffis Minerals is owned by Bob and Sarah Griffis, and we have been buying and selling mineral specimens since 1978, and on the web since 1995. Over the years we have dealt in several large collections, including university and estate consignments. If you have a collection you would like to sell or consign, please contact us.

We offer full appraisal services for your mineral collection, including appraisals for insurance (replacement cost) and for donations (IRS fair market value). Please click here for a more complete description of our services.

A BIT ABOUT US

Bob Griffis - I have been collecting minerals for over 50 years, since I was 8 years old.  I have both B.Sc. and M.Sc. degrees in Geology, worked as a computer systems analyst, and have worked since 1989 as a corporate EHS manager.  I am published in the fields of igneous geology, geotechnical engineering, computer programming and computer applications in geology.  While work pays the bills, my first love is, and always has been, minerals - particularly from classic and unusual places.

Sarah Griffis - I began collecting minerals while in college, and have a special fondness for Sand Selenites and artistic specimens.  I have a B.Sc. degree in Geophysics, worked in the software industry, and published in the field of computer applications in geology.
