Succinite (Resin C10H16O)
Yellow faceted gemstone, likely citrine or yellow sapphire
Uncertain; probable quartz (SiO₂) or corundum (Al₂O₃)
Gemstone-set silver jewelry piece
Likely mixed faceted gemstones in a silver-colored metal setting; stones may include sapphire, ruby/garnet, and yellow sapphire or citrine, but the image is insufficient for species-level identification.
