"Mason-Kay has been in the 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."
