I have found lampwork glass beads to  have a beautiful flowing, organic quality that coordinates well with my pendant designs. These beads are made in the U.S. with glass produced in the Czech Republic, Italy, as well as domestically.  Each is handmade with an assortment of different glasses and annealed in a kiln at over 1000 degrees Fahrenheit.  As with the Murano Glass beads, they will all have some variation so do not expect your earring pairs to be identical. That is, in fact, part of what makes these beads so special and has inspired me to use them in these earring designs.
