About Collet Setting :-Collets can be completely plain or delicately decorative when enhanced by carving, piercing and millegraining. Also known as a bezel setting. The upper edge of the collet is pressed over onto the crown of the stone thereby securing the gem in place. collet has a dual function by forming a cornerstone of the design together with task of holding a gemstone securely in place. Often high quality gemstones are cut for weight and thus come in non-standard sizes. Making your own jewelry collets gives you greater design scope and also elevates the handmade quality of your jewelry piece.
