The Smithsonian recently acquired several new specimens for the National Gem & Mineral Collections during the 2015 Tucson Gem & Mineral Show. One of the pieces, the "Southwest Sunset", was donated by Award winning gem carver Sherris Cottier Shank. The sculpture consists of a 443 ct Ametrine (purple and yellowish quartz from Bolivia) Sun sinking into 1407.77 cts of rose (pink) quartz (from Madagascar) clouds. Ms. Shank has won 8 Cutting Edge awards and this sculpture was recently displayed at the Carnegie Museum in Pittsburgh.
