Pearls exhibit sensitivity to various factors, with chemicals being particularly impactful. To safeguard their lustre and prevent potential damage, a practical approach is to wear pearls last, minimizing their exposure to external elements. When pearls are worn, they inevitably come into contact with your skin, transferring creams, dirt, and other substances onto their surface. A recommended practice is to remove and clean your pearls upon returning home as this practice prevents the accumulation of these substances on the pearl's surface, effectively preserving their integrity and preventing potential damage.
