Smithsonian Scoops Up Dyber’s Dish

Gem cutter Michael M. Dyber presented a Bolivian ametrine to the Smithsonian Institution to be included in its National Gem Collection. Cut in the Dyber style with polished concave bowls ("dishes") and tubes ("luminaires"), the 214.15 ct. ametrine will broaden the collection, which contains mostly traditional cuts. One of the largest and most challenging designs Dyber has produced, the acquisition represents Dyber's lapidary technique, the "Dyber Optic Dish." "I feel honored that the Smithsonian Institution will add my piece to the National Gem Collection and to know that my art will be enjoyed by generations to come," Dyber says. For information on Dyber's work, visit, or call (603) 744-2161.
