It looks like you have some nice, hand-crafted pieces. When things re-open, a trip to a good bead shop would help you identify the materials and give you an approximation of value. The stone in the ring is probably a slice of agate.
Fun! I'm not knowledgeable but am treating this as a fun guessing game!
The first looks like agate in silver.
The second looks like glazed/ enamel beads.
Third looks like red bakelite/plastic beads set with czs
Fifth is a marcasite bead necklace. (Which is actually pyrite)
The bracelet looks like fun color foiled glass or plastic cabochons with smaller crystals
Next look like freshwater pearls that may have been dyed.
My positive guests are:
1. Agate slice in silver colored metal
2. Murano Glass Beads
3. Polymer or red coral beads (50/50 on this one)
4. Hematite necklace
5. Glass Costume Jewelry
6. Freshwater Pearls
