Mojave Turquoise, Mojave Stone…..what is it?

What is Mojave Turquoise or Mojave Stone? (Also spelled Mohave) I could not find a single mention of it in any of my turquoise reference books. On the internet there are some references to it spelled mojave and mohave but I never found any detailed information. When attending a gem show not too long ago, I saw a stack of old magazines with a “FREE” sign by them, so I picked up a few and found this article inside one of them.

From the December 1979 issue of Lapidary Journal – this article made me think it was a mined stone, but…………..

Lapidary Journal December 1979

 

 

 

 

Mojave turquoise was crafted through a process that uses a hydraulic press to organize numerous Kingman turquoise pieces into one conglomerate by introducing a bronze metal matrix throughout the base network of turquoise. Once the turquoise is pressed or assembled, it is stabilized to harden the stone. It ranks 5 to 6 on the Mohs hardness scale.

This was said to be the only product in today’s market that features real Arizona turquoise and real metal matrix. This unique process was created by the Arizona Kingman Mine in Mojave County, Arizona

The trademark was activated in 1975 and expired in 1997.

It doesn’t appear that Mojave Blue Turquoise (as described in the article and these photos) is still being produced. If you have any other reference materials, please let me know and I will add them to this article.

I should mention that I looked through all 12 issues of the 1980 Lapidary Journals and did not find the color photos that were promised in the article at the beginning of this post. I wonder if the author found out that this was a conglomerate and not an actual gemstone that was mined and just decided to not continue the discussion?

It does appear that “Mohave” Green and “Mohave Purple” are being produced today by Colbaugh. They are processed products, often referred to as block stone – see the description under the photo.

From the Colbaugh website “Mohave Green Turquoise – Mix variety of color tone and natural matrix as shown. Blue Kingman turquoise stabilized, dyed green and pressed.”

 

Purple Mohave is also dyed, stabilized and pressed.

  1. The Kingman Mine has been selling these chips in bronze matrix for years, and now I see they are experimenting with a whole array of different stones. I think this technique makes quite magical beads and pendants while recycling otherwise useless but genuine turquoise and stone chips.

  2. Hmmm, I have a bracelet that was given to my dad called “mohave stone”, but never knew what it really was. It looks quite a bit like the examples you show here but with less obvious matrix. Thanks!

  3. Doesn’t it seem like it should not be called turquoise since it is so far from the native stone by being dyed, nearly powdered, compressed, then infused with fake matrix? Thank you!
