Karat (K) measures gold purity; carat (ct) measures diamond weight. Two words, two different things.

Caring for your piece
  • Put your jewelry on after lotions, perfume, and hairspray, and take it off before swimming, bathing, exercise, or cleaning.
  • Store each piece separately in its AURELLE pouch or a lined box to prevent scratches and tangling.
  • White gold is rhodium plated. Re-plating every one to two years, depending on wear, keeps it bright.
  • Clean diamonds with warm water, a drop of mild soap, and a soft brush, then rinse and pat dry. Have settings checked about once a year.
