Our bracelet „Rainbow“ is made of beautiful multicolored Hematite semiprecious stone beads and 100% sterling silver. It´s designed and handmade in Gemany. Because each bead is unique, it´s possible that there are color variations and minimally differences in size oft he beads. Thereby each bracelet is unique and something very exceptionally! The Hematite got ist name by the Greek word „haemateios“ (=bloody). Because when you cut the Hematite the water turns red. The Hematite is very sensitive to heat, salt and acid. Thereby it´s possible that the beads break.
