These four beautiful buckles are bakelite and have an iridescent look to them. Two have brown iridescent marbling, one inlayed with mother of pearl and gold beads. Brown Marbled Mother of Pearl Inlay - 2" W x 1 1/4"H Brown Marbled Iridescent - 2 1/4"W x 1 1/2"H The third buckle that is solid white mother of pearl has a hairline crack in it, it can be used possibly for an item that you will not remove it from - like on a doll but continuous usage might break it in two. I am including as a "freebie". 1 1/4"W x 1 1/2"H The fourth buckle is a navy blue and pale blue marbling with tan. And is a "clip" style. 2 1/4"W x 1 1/4"H Thank you for visiting Forsythia Hill Vintage!
