Gemstones & Beads (4)

I am new at identifying stones, but I got these in a lot of jewelry just like this all bound together with the other lots I am selling. On my Presidium Gem Tester, these test in the tourmaline family. Someone suggested Adventurine. I also see little stones that look like watermelons, red glass beads along with other colors and some sort of tourmaline at the top of each strand. There is also a Millefiore bead on each strand as well.
