Store pieces in the pouch or box when you're not wearing them. Use the included cloth for a soft polish to keep the finish bright. Avoid contact with perfume, lotion, chlorine, and saltwater. They speed up wear on any plated jewelry.

Three materials: sterling silver (925), gold vermeil, and 9K solid gold. Sterling silver is a solid alloy. Vermeil is a 2.5 micron layer of 18K gold over sterling silver, well above the standard for fine plated jewelry. We don't offer vermeil rings on purpose. Friction wears the gold layer down faster on rings than on any other piece, so for ring designs we use sterling silver or 9K solid gold.

Sterling silver is nickel-free. Gold vermeil uses a sterling silver base, also nickel-free. Both are safe for most people with sensitive skin.

Sterling silver darkens slowly through normal use and returns to its original look with a soft polish. Gold vermeil holds up well with reasonable care, but the gold layer eventually wears down on pieces that take constant friction. That's why we don't offer vermeil rings. Solid gold doesn't have this issue and keeps its look indefinitely.
