    I'm not sure an unidentified piece of something in a tube labelled "Jupiter Crystal" is physical proof of pre-Apollo space exploration...

    Could it be a piece of galena? It is a mineral that was used as the crystal detector in early radio receivers. Part of a primitive semiconductor called 'the cat's whisker' for crystal radios.

    This explanation seems the most likely, because in the early days of domestic radio (the 1920s) all sorts of crystals were marketed with exotic names in fancy little boxes and tubes, each brand supposedly more sensitive and reliable than the next. They were sold all over Europe, North America and anywhere else that was just opening up domestic radio broadcasting.

    The crystals were usually about the size of a pea and often sold separately for the 'radio expert' to fit into the crystal radio's cat's whisker assembly often using bit of special solder called Woods Metal.

    This was a period where the public didn't really understand this new magic radio stuff and were kidded into believing any old mumbo-jumbo (where have we heard that before?), and most brands were just the same mineral, usually galena (lead sulphide). Other minerals had similar properties and were also marketed rather extravagantly.

    If you know anyone with some basic radio knowledge, they could easily test it for any semiconductor properties.

    Nick, I have to say: that feels like a very good catch. What you suggest all makes very good sense, and would fit perfectly.

    This page is fascinating... a huge catalog of old crystal radio components. The guy who runs that would be an obvious person to write to personally and ask. (E-mail: scottswim@aol.com)
    One of the images there caught my attention: 'Arcturus Radio Tubes' (!) -->

    Okay, I think we have the answer here (click the link and be amazed!)

    --> http://lmgtfy.com/?q=site%3Aradiomuseum.org+jupiter

    1) Jupiter radios were made by Philips in Germany in the late 1950s and early 60s.

    2) There was also a company called Jupiter-Radio, in Paris in the 1920s and 30s:
    http://radiomuseum.org/r/jupiter_titan_jupiter_8.html

    Here's just one of their models, called the Titan Jupiter:





    I do feel totally certain that a crystal from one of these radios is what you have. In http://radiomuseum.org there's a vast array of images and historical information to browse through.

    Goodness, you've been busy Bill!

    I tried to find an image of a little box or tube of galena crystal in the form it would have been sold to make a crystal set, but only found this:



    I must have seen some at a small display at a vintage radio event. And if Jupiter was a radio manufacturer, it makes sense that in the company's very early days - before the valve/tube era - they sold the crystal detectors for crystal sets. Small pieces as presented for sale look just like the piece in the OP.

    Galena crystals shouldn't be confused with quarts crystals. Quarts has no semiconducting properties, it has piezoelectric properties. But because quarts crystals are ubiquitous in electronics, they are often associated with imaginary, unmeasurable properties in these devices.

    Incidentally, crystal sets had no external power. The sound through the headphones was derived entirely from the tuned signal using a simple resonant circuit. Imagine that - free energy, no battery, no mains. Forgotten or suppressed technology? Er... no. If you make one using much more efficient modern components tuned to any transmitter that is much more powerful than those in the 1920s and 1930s, you'll realise why, even now, they are of limited use!

    But these radios were so simple to make that there are plenty of well documented stories of POWs making them out of razor blades and bits of wire to hear what's going on in the outside world.

    The magic of radio...!

    The bit in the OP about it being "a strange gift from someone high in the intelligence community" does lend it a mysterious quality.

    Sunny-side-up: Had a look at all the Pictures, no match. But could have been a part of these Radios, sounds plausible.
    After looking into the Radio Thing I found a Picture of another small Crystal, looks like mine:

    Please don't feel stupid and you haven't wasted anyone's time - if we weren't interested we wouldn't have bothered researching.

    When something like this is posted on a forum where members have many different disciplines, a sensible explanation often shakes out.

    But it is a fine example of how apparently mysterious things have an obscure but mundane explanation - it's just that finding that explanation is not always possible.

    Agreed, I love threads like this -- allows for some "mystery hunting", and I love everyone's particpation to find more simple explanations before moving on to more exotic ones. Nice work Nick, my gut was telling me this one had an explanation - I did about ten minutes of research but same with Bill initially, I was looking in the wrong ways to easily get to the conclusions.

    Thanks UZN for starting a thread that allows the broad range of knowledge, talents, and skills, on Avalon to once again come to the forefront.

    Yep, changed (never a problem!) to A radio crystal, or physical proof of solar system exploration before 1970? (I also moved it to the What Does It Mean? section.)

    I also thoroughly enjoyed doing the research into those radio sets. Fascinating. Not a waste of time, at all. It was a bunch of fun. This is how I learn things... thousands of others who read the forum, too.

    And it's now on the net, as a reference... anyone else who wants to know what a 'Jupiter Crystal' is, will be led to this thread pretty quickly. All part of the huge library of information we have here. One always finds things out by asking questions.

    And, lastly, if I'd had something like that in my possession since I was 6, I'd want to know what it was, too! So the other thing that happened here was that we all helped a friend.

    I can imagine that you feel betrayed uzn, by the secret service friend from the past.
    Maybe feel stupid for having believed him.

    Well you were only six at the time. Don't forget.

    Agreed with all of the above posts.
    Intriguing OP and nice collaboration from members to bring clarity.

    I hope that this will not hold you back in future postings, since I'm only one of many who enjoys them.

    These rocks looks much to me like TEKTITE.

    Tektites have these little shiny spots and the holes you see on tektites are formed because of the shrinking of the material when falling down from the sky.



    And the style and design of the sticker on the tube feels more like Russian. And such similar type of symbols I have seen on russian books.
