It looks like Anthro's sister site, Urban Outfitters, has come up with a pseudo-Stormy replacement with the multi stone bib necklace ($28). It's not the same thing but I think it evokes a similar look and feel and immediately I must have it.
As a bonus, from now until January 25, you can get free shipping on Urban Outfitters for orders over $75 with code SHIPSHIPSHIP.
FYI: Forever 21 also has a replacement version that looks very much like the Stormy Sea necklace in a deeper green. It's no longer online but there may be some still in stores. You can see Amy rock it here and here.
