This everyday necklace features a gold-plated S925 silver chain and a sphere-shaped nephrite pendant. Adds a rich pop of green to any outfit. Natural and untreated nephrite. Made by handwork of carving and polishing. Because of the gemstone’s natural characteristics, each piece may vary slightly in colors and textures. Weight: 2g Adjustable chain: Gold-plated S925 sterling silver, length 400-450mm Pendant: Nephrite, 10mm x 10mm Product care: Avoid knocking against hard surfaces. Jade pieces are brittle and will break when hit with hard objects. Make sure that you take off your jewelry before you go swimming in a pool or hot tub. If you’re handing dirt and soil, quartz dust in soil is abrasive to the stone. Avoid cleaning your jadeite with any acids or alcohol! It is suggested to only apply water or water mixed with mild soap to get it nice and clean.
