Caring for a yellow gold engagement ring is straightforward, and unlike white gold it never needs rhodium re-plating to keep its colour. BAUNAT crafts these rings in 18 karat gold, meaning 75% pure gold blended with other metals for strength. To clean yours at home, add a splash of ammonia to a bowl of lukewarm water, immerse the ring for 10 to 20 minutes, then brush the diamond with a soft toothbrush and dry it with a woven cloth. Avoid toothpaste, which can cause permanent damage. Remove the ring when using harsh chemicals or lifting weights to prevent scratches to the softer gold. We recommend a professional check and clean once a year to keep the setting secure. See our full guide: How to clean your diamond ring.
