Trancas Pair #18 - each half 2.75 x 2.5 inches (6.8 x 6.2 cm) - $8.00 for the pair
Crystallized quartz Trancas geode with numerous secondary quartz growths and calcites (especially in left half). The photos do not convey the geode very well - this is a pretty good Trancas geode with the combination of calcites and secondary quartz crystals.
