Highly polished nuggets of natural reddish brown amber, graduated in size from 1/4" long to 1/2" long, make up this 24" necklace. There is no clasp; the necklace is strung on string and knotted together, and there are knots between the beads. It is difficult to determine the age of this necklace, as it has recently been re-strung. The beads are nicely matched with only slight color variations to add interest. Most of the beads are clear and most have inclusions of spores and seeds. The amber is from the Baltic Sea area. This necklace weighs only 30.8 grams; amber is so lightweight that it will float in sea water.
