Store your pendant in a soft cloth pouch or a separate compartment in your jewelry box to avoid scratches from other jewelry.
If possible, store it in a jewelry box with a velvet or satin lining to minimize the risk of scratches.
When handling your pendant, ensure your hands are clean and dry to avoid transferring oils and dirt to the diamond.
When cleaning, use only soft brushes and non-abrasive cloths to avoid scratching the diamond or the metal setting.
