This is a nice example of Howlite, pink in color. (This type of stone is sometimes marketed as "Pink Turquoise", which it is not). It comes with a sterling silver bail and an 18" necklace. This stone is indeed Howlite, but it has been dyed in order to obtain the unusual coloration. These come in many variations and are indeed striking.
This sample is good for those interested in collecting the many forms of Agate, Jasper, or sometimes other minerals, or for those interested in pendant jewelry.
