These 4mm faceted round rock crystal gemstone beads are very clear and cut into 64 facets. As is often the case with small, faceted beads, the sides are flat. The faceting and drilling are very good with only a few beads drilled off center.
My supplier assures me that these are natural quartz beads. However, I've heard from gemologists that most of the rock crystal beads sold to the jewelry trade are of synthetic manufacture, meaning they are true quartz but grown in a lab. I will list them as such.
- Bead Size: 4.1mm to 4.5mm
- Strand Length: 15.5"
- Facets: 64
- Treatments: Waxed. Possibly synthetic.
