I think flatware covers it.
I bought a pinky ring from an Etsy vendor a few years back made of flatware but it was silver. It cost a little more but I've enjoyed silver rings for ease of cleaning and it fills the void for ring fingers. Gardeners without gloves ruin gold rings. I only wear one ring these days, not a wedding ring but a nice gift and I hate ruining it in the dirt so I purchased a silver "work ring". It fills the void when I get ready for work, makes the finger happy and silver's not worth much more than dirt these days. YMMV
I do like the butterflies, I've got one small container I think it would benefit. Nifty idea/project.
