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).

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.
