Pale sky-blue agate traced with fine white and lilac lace. Blue lace agate is a rare banded chalcedony; the famous Ysterputs mine in southern Namibia supplied it for over fifty years until 2017.
Priced per piece. Every stone is natural and hand-picked, so colour, pattern and size vary slightly from the photographs.
