Onyx Gemstone Beads 14mm Coin Onyx Gemstone Beads 14mm Coin Approximate Size: 14mm diameter x 5mm thick. Please note the image at left may be larger than life to help show the fine details. Strand lengths are approximately 16 inches long and each strand contains approximately 29 beads. Average strand weight approximately 40 grams. These are very handsome 14mm coins which we acquired as "sardonyx". Some of the individual beads exhibit reddish brown to brownish-grey/black bands characteristic of sardonyx, or mixed black, brown and white bands. However, the overall color is black and white as opposed to sard and white, so we describe and classify them as onyx.
