Mason-Kay Jade Jewelry family-owned and operated in Colorado, USA

Meet the Masons

Husband and wife duo, Jeff and Kristina Mason, run the Mason-Kay home office in Colorado with their fur babies Lola and Ollie.

Jeff is a fourth generation jewelry professional, a GIA Graduate Gemologist and has been in the jade business since the 1980's. Mason-Kay was started in 1976 by Jeff's uncle and father, and he is proud to carry on the family tradition.

Kristina, aka #KrisTheJadeLady, has been in the jade business since the early 1990's and has been designing jade jewelry for Mason-Kay since 2007.

The Mason-Kay Legacy

  • Only Natural Jade

    Every piece of jadeite jade sold at Mason-Kay is guaranteed natural and untreated 'A Jade.' That means NO dyes - NO polymers - NO treatment.*

    *Some jade stones may have a thin beeswax coating to protect the stone. This is not permanent and is not a treatment that impacts value in any way.

  • Exceptional Customer Service

    Whether you're working with us on the phone or through email, you can expect fantastic customer service from Mason-Kay Jade.

    Feel free to reach out with any questions you may have, and don't be afraid to call our office and ask to speak to a jade expert.

  • Jade from Fun to Fine

    We believe jade is for everyone! Ask us about our loose jade stones, inexpensive gift options, and fine jade jewelry over $10k (including the elusive imperial jade!)

    If you don't see what you're looking for on our website, that doesn't mean we don't have it. Call the Mason-Kay office or email kris@masonkay.com with your special requests.
