Our Mini Sphere ball earrings, as well as all your other jewelry, should always be protected from light and excessive air when you put them away. Direct sunlight can damage precious metals like gold and silver, and the metal particles in your jewelry can oxidize with the sulfur present in the air. Both can lead to unsightly discoloration over time. Therefore, ideally choose a non-transparent box or a drawer. Feel free to also check out our Marmor Schmuckschatulle in which your favorite jewelry pieces can best reside.
