Mystery Pink Stone Necklace

Several years ago I bought these stone beads at the Tucson Gem Shows and forgot to make note of what they were. 
They are a stone and possibly dyed Howlite but not sure. They are vibrant with a lot of veining through the beads. They have a weight to them. 
The necklace is interspersed with sterling silver spacers which I made. Two faceted rosequartz sit off center as an accent.
Finished with handcrafted sterling endcaps, chain, hook. Adjustable from 17 inches to 30 inches.
