The combination of pink & white jade and Swarovski crystals gives a mature feel within the cuteness. Also, a heart-shaped rose quartz is placed in the center, making it even cuter and bringing out the natural taste of the gemstones. It's made of elastic, so it's easy to put on and take off. Natural stones: Pink & White Jade Round 10mm, Rose Quartz Heart Swarovski (Crystal) 4mm Asfour Rondelle (Clear x Rose Flower Shape) Made with all my heart. Thank you very much.
