These two interlocking hearts represent so many loves - romantic, friendship, family and absent - to name a few. Which one does this necklace represent for you? It is 16" long, sitting at the base of the neck, with the possibility of lengthening it by 2" more using the chain extender. This necklace is made of Gold Ionic Plated Stainless Steel. And what in the world is Ion Plating? Super thin coating that increases shine, is hypoallergenic and can add any colour or more expensive precious metals (gold, rhodium, sterling silver or platinum) to the steel. 316L Stainless Steel is making stunning jewellery. Stainless steel is an alloy, primarily iron mixed with Chromium. Chromium serves as a protective layer. Chromium decreases oxidation, keeping your jewellery shiny for much longer than Titanium (which is also much more expensive). Protects also from any possible allergic reactions to trace amounts of other metals in the stainless steel. No corrosion No tarnishing No rusting Scratch-resistant End result? Sleep, swim and go to work with it. Caring for it: Wash with a little soap and water. We love it. And so will you.
