Can anyone tell me what this is or where it is from?

This little cup has been in my family for many years. It was given to my grandma from her mother (my great grandma). I have no idea how old it is or where she got it from. I think it is pretty and just have it in my kitchen window but have wondered how old it is or if it's a fake (junk). My grandma was born in 1905 and she has passed away some time ago and I don't know when my great grandma was born but could find out with some research. I do know that they did travel on the wagon train so who knows my ancestory. My mother has more china items stored away also. Well anyways, I thought I would just give it a try, thank you Pamela H. from San Diego, California.
