Please Help: Art theft is wrong, especially when in entangled in a company as huge as Amazon

Amazon is selling what looks to be a necklace that the mold was made out of the clay necklaces one of my acquaintances over on devientart is making.

It looks like the mold could very easily could be cast right from his work, with a mold creator that shrinks after being removed. Those pendents were made with love and care, and each sculpted from clay and hand-painted by the original creator. They put food on his table. As a artist hoping to start creating things like this, I hate to think about what kind of effect this can have, both on finances and his feelings.

If you could leave a 1-star review here:

And nothing that could get the review taken down, so at least sound marginally polite, I'd feel a bit better about the world
