The metal used in ‘pas de marque’ jewelry is very durable. The only thing that can ruin its perfect look is oxidation, which can be easily removed with one of Connoisseurs products: cleansing foam, jewellery wipes, silver jewellery cleaner or a soft silver polishing cloth. But the gemstones and the pearls are very demanding. They don’t tolerate perfume and cosmetics, temperature changes and direct sunlight. In case your gemstones or pearls need cleaning, please use Connoisseurs cleansing foam.
