N.C. Nagle Gems & Beads specializes in a wide variety of colored stones and gem materials with a special focus on natural American Turquoise and cultured pearls.

We believe in full disclosure of all treatments and processes. At shows we offer over 90 different varieties of minerals –from Achroite to Zoisite– and organics used in jewelry or prized by collectors.

Online we are pleased to add a selection of one-of-a-kind finished necklaces featuring rare and unusual gems –rarely, if ever, available in commercially produced jewelry– as well as an array of “loose strung” beads of an uncommon color, source or quality.

We specialize in materials that are not generic, not mass produced and most definitely not easy to replicate.
