- Are these beads really natural tourmaline?
- They are sold as natural black tourmaline. Black tourmaline is opaque, so it looks similar to black onyx; a jeweler or gem tester can confirm the stone.
- Will a 0.8mm hole fit my cord?
- It fits beading wire and thin cord up to about 0.8mm. Thick leather, heavy chain and most elastic cords of 1mm or more will not pass through.
- How many beads do I need for a bracelet?
- At 6mm, an average adult bracelet takes about 18 to 22 beads. One 15-inch strand of roughly 60 to 63 beads covers two to three bracelets.
- Can I use these for a full necklace?
- One strand is 15 inches, so a full necklace needs two or more strands, or these beads combined with spacers and a pendant.
- How does black tourmaline compare with black onyx?
- Tourmaline is a harder, denser natural stone with a slightly more matte look; onyx is usually glossier and often dyed. Tourmaline varies more bead to bead.
- How should I care for them?
- Wipe with a soft cloth and keep them away from harsh chemicals and ultrasonic cleaners. Store separately, since tourmaline can chip against harder stones.
