Vintage 14K Wishbone Pin with 10 White Seed Pearls

I believe this is from the 1950's, this is from my Grandmother's Collection, I have no idea how much sje used this piece, from the pictures it can be seem that this Pin shows no signs of wear with all 10 Pearls still intact. The Seed Pearls are White in Color. I do not know what my Grandmother bought tis piece for in the 1950's so I will guess at a price.
