How to choose and care for your gemstone jewelry?

Choosing a second-hand gemstone jewel means choosing a color, an era, and a use. Caring for it means guaranteeing its intact brilliance for generations.

Which gemstone for which style?

White or blue sapphire naturally pairs with white gold and platinum for an elegant and timeless result. Ruby in yellow gold brings warmth and character — ideal for a cocktail ring or an evening necklace. Emerald, with its green depth, adorns line bracelets and gemstone pendants with rare intensity. Diamond, meanwhile, enhances all metals — white gold, rose gold, yellow gold, platinum — and all types of jewelry, from earrings to necklaces.

Care of gemstone jewelry (the right gestures)

A well-maintained second-hand gemstone jewel retains all its value and brilliance. Sapphire, ruby, and diamond can withstand gentle cleaning with lukewarm soapy water and a soft brush. Emerald, often treated with cedar oil (a stone stabilization process), should be cleaned without ultrasound or steam. For all gemstone jewelry, an annual check with a jeweler allows verification of the prongs (small metal claws holding the stone) and the setting. Each Castafiore piece is checked before delivery — a guarantee of peace of mind upon receipt.
