by mrsjacob » Jan 19, 2012 My husband bought this from an older woman here in town after seeing it on ebay. The only information she had about the origin was that it belonged to her mother and is very old. She believes it's from the 1800s, but I think it looks newer than that. Any guesses? 18k rose gold, 1.28cts of rose cut diamonds, 12x6mm persian turquoise.
