How hard/durable is this alloy? I need to cast fine details in pendant, earring, and ring form.

Yes, it's plenty hard. You can get some fine detail from your cast but not quite as well as you will from silver. There is more weight in the material so it might be too heavy for earrings. Good luck. We put a layer of fingernail polish over the surface to protect and shine.
