Fabulous focal string of gemstone beads on a sterling silver necklace.
The beads are highly polished discs of hematite or "bloodstone" and faceted rondelles of labradorite - lovely translucent with some blue and green flash to them.
They are strung with little silverplated glass beads in between.
The necklace is adjustable between 16 and 18 inches. That's 40-45 cm.
