I filled these myself. It's filled with mostly costume jewelry. My jars always contain 925 and genuine pearls. It's likely every jar contains either 10k or 14k items as well. I don't test the jewelry but it is marked. These do contain broken items as well as unmatched items. Great for crafts and at home jewelry making. *please note. if you purchase the jar with the purple beads. They are genuine fauceted amythest and the 14k gold clasp broke on the necklace. Any purple stone or bead in these jars are genuine amythest.
