Mason-Kay is a jade jewelry brand with an online showroom featuring its jade inventory and designs by Kristina. The website is designed to serve wholesale customers, who must register to obtain login credentials and view the full online inventory. It also directs visitors outside the jewelry trade to a separate option for shopping jade jewelry, making the brand accessible to both industry buyers and individual shoppers.

Mason-Kay’s offerings include jade jewelry, new designs, and estate jewelry. The site provides a jade catalog and information about the brand’s guarantee, as well as guidance on natural versus treated jade, jade colors, jewelry care, simulants, and technical characteristics. Educational resources also cover Chinese zodiac themes and symbols, reflecting the cultural context associated with jade. Customers can contact the company by phone or email for jade assistance, and the website lists trade shows, press and events, trunk shows, and round-table events. Mason-Kay also invites visitors to join its jade newsletter.
