New vintage acrylic black & winter white signet ring

New vintage acrylic black & winter white signet ring Quick list Measurements to come Two tone, minimalist, modern, 50 years old acrylic ring. Lightweight, smooth, shiny. Signet style with creamy white square centre “cabochon” inside the black coloured frame. This creamy white has no greenish tinge that the others do. This is true winter white that has that warm creamy touch. I think it’s the perfect easy accessory for any outfit! Brand new. Vintage c. 1970s. Probably made in China. Also in “white jade” and black. Group photos show varieties. Pardon my old wrinkly chubby fingers! 😝😳🤭
