vintage hinged bangle pair

lovely vintage bangles that i had for long time and was gifted. they both have unique designs and clasps. they also have intact chains. i am unsure of the metals but the black one had gold wash and wear to the metal. and the multi colour one has genuine stone pieces. they are otherwise in good shape considering the age. they are both about the same wrist sizing 7.5 to 8 in. offers welcome 🙂
