Cabochons from today's trip to the rock shop! Larkin has been so lucky to have people offer up stones and slabs for trade or gift. The two cabs on the left with the agatized shells are made of something known as "Turritella Agate" (see https://geology.com/gemstones/turritella/ for more info), the red and black asymmetric drop is mahogany obsidian, the three mossy blue/green ones are moss agate, and the round red and black one is jasper from Larkin’s grandparents’ place in Humboldt County.
