New 925 sterling silver medieval style artisan dangle earrings w mystery stones

Unique Brutalist / Medieval style abstract asymmetric dangle earrings. Handmade by an artisan. With mystery (to me) stones that look like a combination of hematite, labradorite and moonstone. They also sparkle very nicely, like black diamonds. But I can't confirm that. In new condition. 2" long. Not stamped (or I can't find the stamp), but the hooks and the main parts all professionally tested as 925 sterling silver.
