MK Jade Guarantee

Mason-Kay guarantees all our jade to be natural, untreated jadeite jade. Our black jade pieces may be natural, untreated jadeite jade or natural nephrite jade. Mason-Kay does not deal in treated jadeite or nephrite.

Mason-Kay stands behind the workmanship and quality of our jewelry. Please see our Caring For Your Jade Jewelry page on our website for our suggested jade care instructions.
