Mason-Kay Jade

MASON-KAY has been in the wholesale jade business since 1976 selling both loose jade and fine jadeite jade jewelry. In that time, this family owned and operated business has achieved a reputation for the finest quality jade jewelry and superior customer service. Our inventory of natural, unreated jadeite jade is considered to be the largest in the trade and
the U.S. We both buy and sell as well as analyze and assist the trade with appraisals. Our firm is a member of the AGTA (American Gem Trade Association), the JBT (Jeweler’s Board of Trade), the JVC (Jeweler’s Vigilance Committee), and MJSA (Manufacturing Jewelers & Suppliers of America). Please click here and we will help find a retailer near you.

MASON-KAY also has the ability to positively identify treated jadeite (“B” jade) with an infrared spectrometer. Currently, MASON-KAY is the only commercial jade jewelry company to use infrared spectroscopy to test for polymer impregnation. MASON-KAY offers warranty certificates assuring the customer that all jade purchased from MASON-KAY is natural;
we do not trade in treated merchandise.

MASON-KAY’s designer jade jewelry lines have received much acclaim and attention for their trendy, fashionable and colorful jewelry styles. Our award-winning jade jewelry designs from our exclusive designer have launched MASON-KAY to the top of the fine fashion jewelry market.

MASON-KAY makes available to the trade a complete catalog of jade jewelry and a color comparison chart for loose stones. We work with retail accounts, large and small, as a full-service jade resource. Our line is shown to the trade at the JCK show in Las Vegas, the AGTA show in Tucson, and various other trade shows.
