Here we offer a variety of Gemstones in different shapes and sizes. Gemstone strands are 16" length (unless otherwise stated) and we'll give an approx. # of beads of each strand to help you put mm size in perspective. Gemstones are one of the many ways Mother Nature shows us her beauty. Happy beading and please e-mail [email protected] call or text with any questions 1-501-622-6720
