Caring For Your Jewelry This modern metal is very low maintenance and will outlast other metal types without the worry of it losing its shine or fading in color. Although it is a very hard and durable metal, it can still be scratched by abrasive materials like rocks, sandpaper, and even hardened steel tools and utensils. Proper care must be taken of jewelry (regardless of the metal). The good news is that any jeweler in your area should be able to make your jewelry look new again with a little polishing.
