Art Deco dress clips circa 1930 have the mark of "F.N. Co." from the Fishel Nessler company.  Operating from 1885 through 1936, Carl Fishel was one of the founding fathers of the TKF trio of Trifari, Fishel & Krussman.  The F.N. Co. mark is rarely found and the great Deco styling of these clips make them a real find.  The "fruit salad"  style of molded glass stone is a lovely raspberry color and is prong set.  The rest of the piece features pavé set rhinetones in a geometric style typical of the period.  There is some darkening of the stones due to age.  The individual pieces measure 1" long by 3/4" wide.
