Red Brick Jasper Eyeglass / Sunglasses Necklace. Measuring 28 inches long, the colors and marbled effect of this Jasper stone will win you over as a favorite piece of jewelry to wear with your glasses. Jasper is known for its streaks and color variations, but this particular Red Brick Jasper is by far my favorite! Gold tone spacer beads and adjustable stretch ends compliment this beautiful work of nature nicely.
