Vintage Natural Polished Stone Agate Jewelry MCM Bracelet & Beaded Necklace

Two vintage, natural stone jewelry pieces. Brutalist style red agate bracelet, with goldtone, etched metal base. ~7” around. From the 1950’s or 1960’s. Some light wear to goldtone, but otherwise in lovely condition. Beaded stone (I think also agate, but unsure) necklace, with slightly graduated sized stones. Cotton cording, and screw on closure. Unsure of age, but pre-Y2K. ~20 long, end to end. In lovely vintage condition.
