enter image description hereenter image description hereenter image description here Bought these rocks at a shop they were selling as Dragon Jasper,but when I density tested them they were 3.09 which I thought was a bit high for Jasper, and generally Dragon Jasper has Deep red veins, whereas these are much darker.Has a clear streak, the larger piece weighs 68grams dry weight and 22grams water volume leading to 3.09 density. Hardness of 7 on Moh's scale.It is opaque.Slightly attracts a magnet on string.The second picture is from the same batch with minute crystals on the top part with white and green color.The colors in the last two photos are a little different because I used different settings, but the exact same rock before I split it and tumbled it.

  • $\begingroup$ Is the hardness of 7 for the dark red stuff or the green stuff? $\endgroup$ – Gimelist Mar 4 at 21:04
  • $\begingroup$ It has the same hardness for the dark red and green, a stainless knife does not scratch it, even a piece of rough milky quartz did not scratch it. Thank you Gimelist $\endgroup$ – Dave Mar 4 at 21:37

This question is impossible to answer. Here's why:

  1. "Dragon Jasper" is a made up name. It is not a systematic scientific name, and there is no one that regulates its use. It is a commercial name, and people can just give the name "Dragon Jasper" to whatever.
  2. Dragon Jasper is a loosely used term. Some websites claim it's found in Western Australia, others say it's found in South Africa. Even coming from the same mine site - some will look better and others will look worse. Where do you put the line?
  3. In these types of stones, sample preparation is very important. Sometimes the visual qualities depend a lot on the type of polishing, the cut of the stone, etc. The exact same raw material will look differently depending on how you prepare it.

To me it looks like some jasper (which is just silica - one of the most common materials on the planet) which some green stuff on it which could be anything (chlorite? epidote?). These are very common minerals, and someone decided that when they look in a certain way they will call it "Dragon Jasper". It is pretty much meaningless. It is possible to do a full scale analysis including isotopes and trace elements to fingerprint where it came from, but if it turned out to come from South Africa would that make it any less "Dragon Jaspery" than one that came from Western Australia?
