  • June 2006 to present:  Owner and sole proprietor, Mary Johnson Consulting
    • Emerald durability project for GIA
    • Monthly column for National Jeweler: Good Question!
    • Working on a couple of projects I can’t talk about yet, involving archiving and other activities. Stay tuned.
  • This summer, a patent of mine came through, on a simple device to see fire in gemstones: U.S. Patent 7088434. If you are interested in this device, please contact the Gemological Institute of America, as the patent is assigned to them.
  • 1996-2006: Manager of Research and Development at the Gemological Institute of America, in Santa Monica and then Carlsbad CA.
    • Wrote many peer-reviewed articles, wrote trade articles, talked to the press, etc.
    • Edited a News section for quarterly trade journal, Gems & Gemology. I am still on their article review board.
    • Managed the GIA Diamond Cut project for a few years. Won GIA Staff Member of the Year award for 2001 for my work on this project.
    • Developed techniques for analysis of observation data, methods for identifying black opaque gem materials, etc.
    • Authored and gave presentations on emeralds in Bogotá, Colombia; Hong Kong; Taipei, Taiwan; New York City, etc.
    • Visited diamond mines in Canada and emerald mines in Colombia.
    • Demonstrated new crystal growth in high-temperature treated rubies.
  • 1996: Developed an ongoing fascination for wolverines (Gulo gulo).
  • 1993-1996: Staff scientist in Gem Trade Laboratory, GIA, Santa Monica. Helped identify esoteric gems, checked identification criteria, wrote articles and news entries, etc.
  • 1991-1993: Volunteer curator, Department of Mineral Sciences, Los Angeles Museum of Natural History. I identified samples, helped organize acquired collections, designed and set up displays, trained docents, and arranged loans. I was visiting curator on the Smithsonian visiting exhibit, “Inside Active Volcanoes.”
  • 1991-1992: Provided data analysis of shock wave data (including literature search in many languages) for 2 volumes of T.J. Ahren’s Handbook of Physical Constants, AGU Reference Shelf Series, 1995.
  • 1986-1991: Member of Technical Staff, Division of Earth and Planetary Sciences, California Institute of Technology, Pasadena CA.
    • Mapped low-concentration transition elements with electron microprobe.
    • Studied early solar system meteorites.
    • Simulated conditions of volcanism on Io.
    • Purchased an SEM (on grant money) and demonstrated its use for combined visual and chemical analyses.
    • Introduced Peter Tsou (JPL) to aerogel.
  • 1983-1986: Postdoctoral position in physical chemistry, UCLA
    • Studied ammonia-water phase relations in a diamond anvil cell
    • Did shock-wave luminescence experiments at Lawrence Livermore National Lab
    • Held a DOE Q Clearance.
  • 1977-1982: Graduate studies in mineralogy and crystallography, Harvard University, culminating in a Ph.D.
    • Ph.D. Thesis: The Effect of Substitutions on the Physical Properties of Tetrahedrite.
    • Taught evening gemology as a teaching assistant to Cornelius Hurlbut; taught general geology as a teaching assistant to Steven J. Gould.
  • 1976-1977: Member of Technical Staff, Division of Earth and Planetary Sciences, California Institute of Technology, Pasadena CA.
    • Hydrogen and oxygen isotope studies of tree rings and climactic change.
  • 1976: Curated a private collection
  • 1972-1976: Undergraduate studies in geochemistry, California Institute of Technology, Pasadena CA.
    • Advisor was George Rossman
    • Studies of dioptase cause of color; rare-earth-element measurement with an electron microprobe; economics of energy generation; and ion activity measurement.
    • Trained rhesus monkeys.

 

And some of the fun projects:

  • August 2006 to October: Kumihimo (Japanese cord braiding) project. A perfect craft to keep oneself occupied during flights, as no sharp objects are involved.
  • July 2006: Booth volunteer at Comic-con, San Diego, part-time for 5 days. Sold TPBs (trade paperback graphic novels) to specialized and general audience, provided advice, sorted stock, etc.  At our booth, we made a healthy profit this year.
  • February 1977 and 1991-2006: Worked at, reported on, spoke at, and otherwise attended Tuscon mineral, gem, and bead shows.
