I always get a bit paranoid about things getting damaged and bent too easily. And I know it's not always reasonable, I had a hard time accepting to make things like earrings with intentionally weak links for example (I used to make the whole thing extra strong, and then realized that if something pulls on the earring, it's better for it to break than for the ear itself). Even with a pendant, you can have a coat on top, the strap of a bag, etc, and I start worrying that it would be ruined by such an easy mistake.
I'm definitely not a jeweller either, I just picked up a hobby of crafting pieces with a saw, and as such I'm rather limited in my knowledge of other methods.
Who knows, I might try casting eventually. I have the basic tools to do it, and some tin that I could melt, but that would be for a very different style since you can't make much in tin without it bending ^^'
