Subject:There are NO nephrite jade in California?
Posted By: Bill Thu, Feb 05, 2009 IP: 192.55.208.10 I was flabbergasted by a supposed-to-be jade expert and jade book writer�s recent comment in this forum that �nephrite was never discovered in Taiwan� |

Subject:THE TRUTH
Posted By: JadeJunkee Fri, Jan 15, 2010 I'm not sure where to start...not sure what folks are trying to say on this old thread...but here are the facts. Nephrite jade is found in Alaska, British Columbia Canada, Washington State, California and Wyoming....some other states MAY have jade (Oregon, as Micheal pointed out has some small deposits). Hydrogrossular garnet (HGG) is distinctly heavier....but that is not what is being called jade. They are formed together, in the same kinds of enviroments. In northern CA alot of the "jade" is vesuvianite (+/- hgg) in Wa the HGG is (+/- vesuvianite) niether are jade, but are found along side the real jade (nephrite)...follow? There are several (or were) nephrite (not hgg) mines in WA that shipped to China...why? Because only China purchased in quantities that could support the mines. I have a lot more info for those interested....btw all the botryoidals are nephrite jade...nothing else. |
Subject:Re: THE TRUTH
Posted By: Allan Sun, Feb 21, 2010 I was just reading through a lot of this thread which I find very interesting. I collect jade in the Big Sur area and have recently been working the gems. Difficult but fun. I wanted to make one comment to Bill and the rest. An example of what Tony might be saying is from a post Bill did about the Vonson Blue. I have held this stuff in my hand and there is no way it is nephrite or jadite. It is way too light. The density is just not there to be anything related. Even though it is stated as being a "blue jade" I highly doubt it is. |
Subject:Re: THE TRUTH
Posted By: JadeJunkee Sun, Feb 21, 2010 That's interesting Allen....do you know if any samples have ever been properly tested? Folks will call everything jade without real proof to back it up...especially if real jades are known from a region..it makes it all the more believable. I certainly don't want to get involved in an old bitter argument though. I'll have to look up this variety of "jade" and see what info is out there. But without the "heft" you are right...no way it's jade :-) |

Subject:Re: Vonson Blue
Posted By: JadeJunkee Tue, Feb 23, 2010 Sorry Bill..I have no idea about the jadeite issue in California...I've heard that it's there too...and I know of one location here in Washington, but don't have a confirmed sample ...yet:-) I will ask around, but I bet Allen knows something about it. I've been meaning to ask about it myself anyway. |
Subject:Re: Vonson Blue
Posted By: JadeJunkee Thu, Feb 25, 2010 Yes...there is jadeite tested and confirmed in both WA and CA. |

Posted By: Allan Fri, Mar 12, 2010 Hey guys, |
Subject:Re: Jadeite
Posted By: Donald Kasper Sun, Oct 01, 2017 Infrared spectroscopy of samples I dug at Clear Creek confirm jadeite, as well as XRD from a prof in New York. The Jade Cove material is nephrite in IR. A sample I obtained today of the Vonsen material is clearly actinolite. Since it is not fissile, it is solid, without obvious actinolite needles to the naked eye, this is clearly nephrite, which is a variety of actinolite. It is the only Norcal coastal nephrite I have scanned in infrared. Most are diopside, serpentines, vesuvianites, clinochlores, and even a green albite is in the Smith River. |
Subject:Re: Jadeite
Posted By: Allan Sat, Mar 13, 2010 I thought I had a some jadeite from clear creek from a rock hound to offer some samples. I just tested the S.G. on it. Came in at 2.65. I think it is a gem grade serpentine. Oh well. |
Subject:Re: Jadeite
Posted By: JadeJunkee Sun, Mar 14, 2010 how about some vonson blue? perhaps those test results I posted aren't represenative. I just emailed a guy here in Washington who is selling some of his old collection...I'll cut the piece I get in half and send you a piece once I get in contact with him. Maybe he has some clear creek stuff? |
Subject:Re: Jadeite
Posted By: JadeJunkee Tue, Jul 13, 2010 Here is an ebay item from a trusted source...75lb clear creek jadeite boulder...hope this is what you were looking for. Clear creek is closed to the public now...might be your only oppertunity. |
Subject:Re: Jadeite
Posted By: allan Wed, Jul 28, 2010 I now have some clear creek jadeite in my possesion. I have tested the larger stuff for the S.G. and tested smaller chips and cuts and confirmed it is. If Bill or anyone wants some, we can work out a deal. I can cut slabs or send rough. Let me know by my personal email. [email protected] |
Subject:Re: Jadeite
Posted By: Donald Kasper Wed, Sep 27, 2017 There is no question whatsoever that jadeite exists in several pods in Clear Creek. An X-ray study of it was done by a jade expert (who sent me the graph of the results) out of New York, and I have scanned it in infrared. |

Posted By: Linda Henris Sat, Aug 17, 2013 I am the granddaughter of Magnus Vonsen. I have some of his Jade, Vonsen Jade, Pacific Blue...When the ranch was sold in the early 60's, in the Deed of Sale, it was stated that the Mine was NOT to be mined at all..I am seeing the Jade on ebay and other places over the years. Attached are 2 foto's first is polished stones and second is raw. |

Subject:Re: Vonson Blue
Posted By: Donald Kasper Wed, Sep 27, 2017 It doesn't matter what the SG or RI values are. What matters is a method of spectroscopy, X-Ray, Raman,or infrared says. You have some vonsen pieces to send me, I will scan them in infrared. |
Subject:Re: Vonson Blue
Posted By: Donald Kasper Wed, Sep 27, 2017 You have a chunk an inch or two in size, I will buff it flat, roam around with reflectance infrared laser and see exactly what it is. I have not seen a Norcal coastal or Coast Range jade yet. Everything in the serpentine group, yes. Nephrite, no. Usually diopside. EEl River, is not jade. |
Subject:Re: Vonson Blue
Posted By: Linda Henris Thu, Sep 28, 2017 I do not need the Vonsen Jade scanned. I know and so do many other mineralogist know what the Vonsen or Pacific Blue Jade is. |
Subject:Re: Vonson Blue
Posted By: Donald Kasper Wed, Sep 27, 2017 Optical properties to ID jade are worthless. You have some vonsen blue, I will scan it with infrared spectroscopy which will tell us exactly what it really is. |
Subject:Re: Vonson Blue
Posted By: Maus Thu, Jun 07, 2018 I live in northern California and have a variety of jade(maybe?) samples I've collected along the coasts; including blue material, some white / clear material I suspect to be jadeite, and a bunch of other stuff that I suspect to be things like richterite, vesuvianite, aegirine-augite, etc. but I could very well be wrong. |
