Dentalium Shells: These natural Dentalium shells are of the highest quality we have seen yet. They are often used to replace hair pipes in chokers to result in a very delicate piece of jewelry, or to make earrings as they did long ago. They come in sizes ranging from 3/4" to as much as 1 1/4". They are available in a 1 ounce pack (approx. 330 shells per oz) or you can purchase them by the 1/4 pound (see product title).
