Peach Sapphire, like most other gemstones, tends to collect dust and dirt over it, which over time can affect the luster and quality of the gemstone. However, it is pretty easy to clean the gemstone. Use warm water and mild soap to wash the gemstone and a soft brush to scrub off any dirt from the surface of the gemstone. Rinsing it with lukewarm water and drying it by wiping with a soft cloth will retain the shine and quality of your Peach Sapphire gemstone.
