     Arizona's Oldest Mineral Society


The MSA Club

ESTABLISHED:  December 4, 1935  

FOUNDER:  Mr. Arthur L. Flagg

ORGANIZATION:  Non-Profit 501[c](3) Educational Organization.  All contributions to MSA in the United States are tax-deductible to the extent provided by law.   



PURPOSE/MISSION: To promote popular interest and education in Earth Science, and related fields (Geology, Mineralogy, Paleontology, and Lapidary arts); to foster a fellowship among individuals interested in Earth Science and enable our members to better identify materials we collect, and how to display or further process these materials; to teach all generations about rocks, minerals, fossils, and what can be done with them, and be collaborative in community of groups with similar interests to our Society.



PHOENIX HERITAGE MINERAL SHOW (PHMS): Focus on well-known, top-quality mineral dealers with a select representation of high-quality gemstone, jewelry, and fossil dealers. The goal of our show is to bring exceptional minerals to the underserved mineral collector and to be a gathering place where collectors can cultivate their passion for fine minerals and enjoy good fellowship with others in the mineral collecting community. PHMS exists to fill a niche not found in most club shows.

Quality is our guiding light as the PHMS Show Committee seeks out and invites highly regarded dealers known for their stunning displays, superb inventories, and loyal customer followings of dedicated collectors.

PHMS is The Largest, Quality Mineral Show in the Phoenix Area catering to mineral collectors and offering them an annual destination to look forward to each year.

The MSA Logo

Mineralogical Society of Arizona (MSA) logo design is inspired by the following MSA members:

MSA Co-Founder and President Mr. Arthur L. Flagg, who serves as the rock foundation and prospecting roots of our society.

MSA President Dr. Raymond Grant whose presentation "Basalt to Wulfenite or How Arizona Got So Many Minerals" was inspiration for Chris Whitney-Smith's logo designs.

MSA President Mr. Chris Whitney-Smith, designer of MSA 75th Anniversary Pin and 2012 MSA logo, united symbolism of MSA and mineralogy and ultimately championed campaign to make Wulfenite the Official State Mineral of Arizona.

MSA Board Governor Mr. Don Boushelle, who designed Flagg Mineral Foundation's 2016 logo and whose distinguished artisan vision in collaboration with Chris Whitney-Smith, created in 2016 an MSA logo with symbolism that honors MSA history, pays tribute to MSA's enduring future and features a Red Cloud Wulfenite in support of Wulfenite as the Official State Mineral of Arizona.
