Most of these items were purchased as souvenirs from museums. The fossils include three ammonites, one goniatite, one fusulinid, and five other fossils of unknown types. There are also seven bismuth crystals of varying sizes. I think they are all quite beautiful. Also, one of the ammonite fossils has an iridescent sheen that can be seen depending on the angle. How about using them for interior decoration, research, or making accessories? Instant purchase is OK. Shipping will be via Yu-packet Post. I will ship either on the same day or the next day. For this item, I will always consider a price reduction if it's not a significant markdown. Feel free to negotiate the price or ask any questions! Type...Other Type...Ammonite
