Natural gemstones are always a great beading choice. These beads combine natural gemstones with a sterling silver core to make them easier to thread. With at least a 3.5mm hole, these high quality beads are perfect for stringing on your favorite large wire and finished necklaces, particularly the Caspia™ necklaces and bracelets. These beads can be used alone or strung with other beads for a fun, complementing design.
