  1. With authoritativeness, you can rest assured testing.

    The national light industry jewelry and jade jewelry quality supervision and testing center is Shanghai's first measurement certification of the National Technical Supervision Bureau [CMA (95) recognition (national) word (C1359)] The statutory quality testing agency of Baoyu Stone has passed multiple measurement reviews.
