I'm fairly sure the oval pc. is a brooch. The larger pc. looks much thicker, and I'm not too good on horse and buggy parts, but based on where you found it may be a rosette ? (albeit a fancy one)
Both pcs. look fairly early. a little hard to tell date without the attaching parts of either. But judging from the discolored areas on the oval, the brazed areas indicate a pin setup and may have been a simple wire pin and hook.. So, it could be late 1700's to early 1800's ! Very nice finds..
The thing that gets me, is that almost all the jewelry I have found from early 1700's to early 1900's are mostly brass and then gilt. Gold or silver. I can spot flecks of both on almost all the early jewelry I have found. I have found only a few very small solid gold pcs. usually added to a larger pc. And solid silver pcs. are a little more findable. I have a brooch with perfect rubies in it, so you'd think they would have gone all the way with stones like that and used gold, but nope ! It too has a brass base with a gilt covering, and it's about early 1800's.
I wonder how many people have found solid gold wedding rings made before the late 1800"s ?? So far all of mine have been brass/gilt.
