This years theme of the 2023 Tucson Gem and Mineral Show® was “Silica – Agates and Opals and Quartz, Oh My!” There was an abundance of fantastic Quartz crystals filling many display cases, as well as many fine Agates of all different varieties. Opal was not well represented, considering its rarity relative to Quartz and Agate, but there were some scattered specimens to be found. Overall this was a great theme and I loved some of the minerals chosen. Please see the pictures of some of the highlighted minerals on display below.
