Donate 2/24 Sisi Amber bangle - I broke it, can you solder?

This bangle is gorgeous, and I’d be happy to wear it without the charm, but it would be incredible if someone handy could restore it. From Sisi Amber in what looks and feels like pewter, engraved, embellished all around with dark stones. I’ve shown the original in last shot and closeups of damage. Otherwise good used condition. Weighty!
