One short strand of 6mm round crystal glass beads, with about 50 beads on each strand. These are inexpensive glass beads, but they are very smooth, with good color and excellent clarity.
The beads were made in China, and they appear to have been hand-made. There may be variations in the exact shapes and sizes of the beads, the size of the holes, etc.
In my opinion, crystal glass beads are some of the most beautiful, well-made and durable types of glass beads around. They have a chemical formulation that makes the glass harder than usual; which increases the index of refraction of the light rays; which increases brilliance, color, and clarity. (Crystal beads that have shiny metallic effects or iridescent Aurora Borealis are an exemption to this rule. The AB and metallic surface coatings tend to be very fragile, so I prefer not to use those kinds of crystal glass.)
Please be aware that photographic computer images of bead colors are tricky things; varying according to lighting, the whims of the camera, and your individual computer monitor display. Photo colors can appear dramatically different when viewed on different computer monitors. (High def monitors intensify most colors, mutate others, and can even turn regular colors neon bright.)
Even in person, beads can be little chameleons, changing colors dramatically when viewed in different lights. When you receive your beads, you should look at the colors in natural sunlight as well as by indoor light. Beads can change from blue to purple, clear to yellow, gray to amethyst, etc.
