Artisan modernist rustic style sterling silver boxy post earrings, unique.

Artisan handcrafted. No markings found but I have tested posts and the metal on the earrings and it is sterling silver. Stone looks amethyst to me however I can be wrong. Note: One of the posts is slightly bent but won't affect the wear. I do not have spare sterling backs for the earrings. Silver is not polished.
