Both of these i'm not positive.  The black is supposed to be black jade from arizona and the secon luna agate?  Anyone know for sure.  I thought the black will look great on the doublets.

I would say yes to the Luna...

Hard to tell from the pic if the other is black Jade as it looks a bit gray like porcelain.. Probably just the way the image turned out..

Is it black ?

yes its black,  clints looks gray on his website too. If you look up az. black jade, its really not a jade.  But i was wondering if this looks like the same rock, because its pretty expensive.

Here is a bit more info on the Arizona Black Jade, ( Absolute Black ) not sure if you have ever seen this before. Try to polish your slab if you have very small pits, it could be Basenite, this is another mineral that comes from Arizona and is hard to tell the difference, Basenite would be a better choice for backing as the black jade would make a better cabochon. The first is a pendent I made when I first started, it is made from the Absolute Black, the secound Picture is Basenite, they are both grey in color and polish up jet black. I have found both in the same area. Nothing is more embarrassing than selling the wrong thing.

You sure did get a polish on that one! I only use basenite for a backing material. My favorite out of the black jades is the magnetite jade that was found in California.

I have a small amount of that Jade with the magnetite, I was told after cabbing, the magnetite can be Gold electro plated?? I don't know this for sure, but it would be very cool looking.

Ya, i would agree with Clint and lean more towards basonite for sure.   The problems lies, as Rob notes on his site. This AZ black jade is not real jade. But a term used to market it better.  Hence in most cases, unless you buy it from the driect soruce or mine it yourself. I wouldnt even try(myself) to market it at $50 per pound without a true soruce confrimation.     Rob is a good Soruce, ive worked with him before when he was bring in allot of African Blue Chalcedony. 

Clint, That sounds like What Seth is talking about, Magentite in jade.  Magnetite will generally looks like hematite.

The first sample looks to me more like a tube agate and not luna agate. Luna usually has more white and purple and almost nothing else. The second could be what they sell as Arizona Jade, it is very similar in nature to the Australian jade I use. Takes a good black polish, but is not really translucent at all. I have found both the Australian and Arizona much easier to get a polish on than any of the Wyoming, California, Alaskan, etc. But the others tend to be a bit more translucent when finished.

I too like the jade with magnetite, and yes I have seen it finished with a gold electro-plate. I was told it's a multi-step process with two other metals used first and that most is done with a pen-platter.
