Keeping your pearl jewellery clean is simple yet essential. Gently arrange your pearls on a soap, dirt and cleaning solution-free benchtop (all three can harm your favourite piece), and begin to wipe each gemstone with a very soft cloth. Stay away from any chemicals or compounds, as these can erode their lustrous layers. Avoid using heat and water. Pearls are quite delicate and require more gentle care than harder gemstones.
