Mid-Century, circa 1950's, 14K gold carved rose brooch or pin, set in a very elegant setting of 14k gold, and secured by a hinged pin. Signed KL 14k. I've seen several of these, usually marked gold filled, but this one is clearly marked 14k. Karen Lynne was a very desirable designer for the Charles Rothman Company, famously tied to Beverly Hills, Boca Raton, and Cave Creek, AZ.
It measures 1 1/8" high, and 1" wide, and weighs 4.8 grams. It is in wonderful vintage condition with no signs of damage.
