Keep It Away From Chemicals: Keep your jewelry away from perfumes, lotions, chlorine and harsh cleaners. Let skincare dry before wearing your piece.

Clean Gently: Clean with warm water, mild soap and a soft cloth. Avoid abrasive cleaners that can scratch the metal or dull the finish.

Store It Separately: Store each piece in a soft pouch or lined box to help prevent scratches, tangling and contact with other jewelry.

Remove Before Activities: Remove jewelry before swimming, showering, exercising or sleeping to help protect the metal, setting and your moissanite or lab grown diamond.
