Lampwork 101 for jewelry. I wanted to show you an example of what to look for in really good quality artisan lampwork beads. These beads are by "Bluff Road Art Glass" and they are some of the very best in regards to quality and execution (and some of the highest priced). Even if this style or color isn't for you, look at the dots, see how perfectly uniform they are. The dots and raised stringers (raised lines of color) are well attached and not in any danger of popping off.
