Are Dora rings allergy friendly?
Yes, as DORA rings are made in Europe they must conform to European standards which are the toughest in the world. DORA are also sold in the USA so we had the American Assay & Gemological office conduct a series of tests for corrosion, wear and nickel release. The results reported that the nickel release in 18k & 9k white gold registered just 0.1 milligram per square centimetre of the item per week.
