Heart charm in stainless steel 15mm in gold

With its resistance to rust, oxidation and discoloration, this corrosion-resistant alloy is ideal for long-lasting jewelry designs. It's also unplated and will not fade or chip over time. This metal is the best suggestion for those living in high-humidity locations, as the metal will keep from rusting much longer than other metals.
Jewelry made with these findings will endure heavy wear longer than those made with carbon steel and softer base metals. Jumprings and loops made in headpins and wire are less likely to come open under the weight of pendants or multi-layer designs.
Because many stainless steel jewelry-making supplies are unplated, they are an excellent alternative for wearers with allergies and sensitivity to base metals such as copper or brass. For designs where the findings will be in close contact with the wearer's skin (especially in the summer-time when heat often exaggerates the reaction to skin) unplated stainless steel is one of the best options available. Stainless steel may contain some nickel, but it's generally considered hypoallergenic for most people. This is the reason that type 316L stainless steel is often used as starter earrings for newly pierced ears.
