Using this Verragio 18k Diamond Circle Pendant Necklace is super easy. Just adjust the chain to your preferred length between 16 and 18 inches and put it on. When not wearing it, store it in a jewelry box to prevent scratches. To keep it looking shiny, clean it gently with a soft cloth. Avoid exposing it to harsh chemicals like bleach or strong detergents as they can damage the gold and diamonds. If you're doing any strenuous activities, it's best to take it off to avoid any accidental damage.
