The "IR" stamp on jewelry typically indicates that the piece is made of iridium, a dense and corrosion-resistant metal often used in high-quality jewelry and watches. This stamp can also signify that the item is part of a specific brand or designer's collection. It's important to verify the context, as stamps can vary in meaning across different manufacturers. Always check with the jeweler for precise information regarding any stamp on your piece.
