Mineral Masterpiece is a joint project of Thomas Spann and Irv Brown. They offer fine mineral specimens and gemstones from localities around the world chosen for their superb aesthetics and overall high quality. 
Separately, Irv Brown has worked with elite level mineral specimens for the last 15+ years, and is known for his keen eye and reputation for putting together world-class displays and collections. In 2009, Irv joined Tom in order to present high quality mineral specimens online at http://www.mineralmasterpiece.com 

Tom completed his Graduate Gemology degree from GIA in 2008, though his passion for minerals began as a child collecting in Connecticut. Soon after his parents, Jim & Gail Spann, began collecting in earnest, Tom chose to join the mineral community as a dealer in his own right. His photography fills the galleries of Mineral Masterpiece. 

You can find Mineral Masterpiece at the Westward Look Mineral Show in Tucson in Room 222. They are also available by appointment at their office in San Diego.
