Do your pieces come with certification?

Select diamonds include grading reports from recognized gemological laboratories such as GIA, GCAL or IGI.

How should I care for my jewelry?

To preserve the beauty of your jewelry, we recommend removing your pieces before exercising, swimming, showering, or applying lotions and perfumes.

Store each piece separately in a soft pouch or jewelry box when not in use.
