About Mason-Kay

Mason-Kay has been in the wholesale jade business since 1976 selling both loose jade and fine 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, untreated jadeite jade is considered to be the largest in the trade. We 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) and the JVC (Jeweler's Vigilance Committee).

Jeff Mason, president of Mason-Kay since 2007, has been in the family jade business since the early 1980's, receiving his Graduate Gemological degree from GIA Santa Monica in 1984. Jeff is a fourth generation jeweler and was elected to the AGTA Board of Directors in 2015, serving until to 2019.

In addition to trading in natural jadeite, Jeff has also created one of the most trusted jadeite labs in the industry within Mason-Kay, offering testing services for appraisers, stores, auction houses and individuals, as well as providing value estimations where appropriate. After over 30 years of experience, Jeff has become one of the leading jadeite jade experts in the U.S.

Mason-Kay has the ability to positively identify polymer impregnated jadeite ("B" jade) using infrared spectroscopy. Currently, Mason-Kay is the only commercial jade jewelry company in the U.S. 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 the beautiful and colorful jade jewelry styles. Our award-winning jade jewelry designs from our exclusive designer, Kristina, have launched Mason-Kay to the top of the fine fashion jewelry market.

Mason-Kay makes available to the trade an Online Jade Showroom and the Mason-Kay Colors of Jade Chart. We work with retail accounts, large and small, as a full service jade resource. Our jade collection is shown at various trade shows including JCK Las Vegas, the AGTA Tucson, the Atlanta Jewelry Show.
