What are These?

And why three large and four smaller?

Tuxedo/shirt studs?

I would also say Tuxedo/Shirt and formal waistcoat/Vest for the larger size ones ?

Nice, I hope you can get those tested as they really look like gold plated, if not gold from here. I've never seen them with gold coloured pins which is what makes me think this. Plus being a custom order they tend to be a higher quality to begin with.
