Elegant and classic, perfect for business or an evening concert! Five blue lace agate slabs (used to induce high states of consciousness) in shades of blue gray, pearl, and edged in brown, are cool and smooth against the skin. Other features of the 20" necklace include chalcedony rounds, pewter spacers, and fine faceted purple crystal. The Carole MacKay designed magnetic clasp is attractive, sturdy. and oh, so easy to click on and click off. No fumbling! You can wear your own earrings, but a matching pair is part of the set.
