Vintage 1930's Sterling Silver Gold Vermeil Celluloid Coral Rose Brooch Pin

While researching, I came across a necklace that matches this Brooch presented as antique 1920's- However, the rollover safety clasp on this pin dates to the 1930's, and it's understandable that estimating age could be a bit off without a tell tale sign, such as a clasp. Either way, this lovely dainty brooch is almost 100 years old, and in lovely condition for it's age. Marked STERLING with a Gold Vermeil finish. Has some naturally developed patina, and does show signs of wear. The rose in the center looks to be a bit offset, and I can't say for certain if that was due to a repair at some point, or if it was originally made like that. I wouldn't consider it a flaw, but am mentioning it, because I understand how it could be bothersome to a person.
