Why Does Your Jewelry Still Tarnish? You Might Be Using the Wrong Supplier

Tarnishing isn’t just a minor issue—it damages your brand’s reputation, increases return rates, and discourages repeat buyers. Unfortunately, many suppliers use outdated coating methods that fade quickly with wear.

At DOTTO, we use advanced PVD vacuum coating to ensure our jewelry is non-tarnish, waterproof, and highly durable. Every piece meets REACH compliance standards, making it safe for both skin and the environment. Your customers deserve jewelry that keeps its shine—and so does your brand.
