Colorful bead necklace using natural stones. - Materials: Natural stones (rose quartz, amethyst, jasper, etc.) - Design: Bead necklace - Colors: Pink, purple, red, white - Length: Approximately 45cm Thank you for viewing. There is a quality assurance certificate from the jewelry shop. It's faded because it's thermal paper, but it says "aventurine necklace." I wore it 2-3 times, over a turtleneck sweater. I'm selling it because I no longer like the colors.
