Rhodochrosite Gemstone Information - GemSelect

Rhodochrosite is a fairly soft gemstone, so it should be cared for in order to prevent damage. Since dust contains quartz, which has a Mohs scale hardness of 7, simply wiping dust from a rhodochrosite gemstone could cause scratches. The best way to clean rhodochrosite gemstones is by using soapy water and a soft cloth.
