This black, suede leather, drawstring, necklace pouch measuring: 11 x 8.5 cm. (4 1/4" x 3 1/4"),  has for its centerpiece, a round, 20 mm. onyx cabochon around which I  did backstitch; using black, leaf green, brass and mahogany red size 10, seed beads.  
This, I beaded to the bag, by doing brickstitch, using black, size 8, seed beads.  

The 110 cm. (43") black, suede leather cord drawstring is finished at the ends with leopard skin jasper ovals, onyx and fancy jasper rounds, and brass rondelles all tied on with 7 strand beading wire.  

The drawstring has two sliding, lock beads.  (See last picture).  
One, a black bone bead, holds the pouch tightly shut, while the other, a brass donut, adjusts the drawstring length, so, it can be securely looped around a neck, waist or purse strap.

This pouch will keep your treasures safe.
