Birthstones should be cleaned regularly to keep their shine. They may be cleaned safely using the following methods:
1. Use ultrasonic cleaning for your jewellery to remove build up of impurities and gunk.
2. At home, use diluted detergent for cleaning; please note: do not soak diamonds in detergent water for an extended period; normally, as long as the diamond is in touch with diluted detergent water, except for some inaccessible gems, the diamond is clean. Even with excuses, the majority of the space could be cleaned. Although the detergent is an alkaline product, the amount of alkaline components in it is insufficient to harm jewels; therefore, it may be used with confidence.
3. Avoid acids and alkali; even inorganic jewels cannot tolerate them.
