Coral Nuggets These high quality red coral nuggets are good sized nuggets with good volumn and color. They are all drilled through the center adding a new dimension to your jewelry. They come strung on 15" temporary strands, or are available as 1/4 or 1/2 strand portions. Please note that they do graduate in size from small to large as shown, so when you purchase a 1/4 portion of a strand you may be purchasing either the end portions or center portions as our current supply provides. The difference between the sizes is minor, as you can see in the photo, but may involve the thickness as well as the length.
