I cut cabs for wire wrapping that my wife and daughter do and for other jewelers.  I have a show this weekend which is stones only.  We are dealers at the Agate Expo in Cedarburg this summer  and newer material, like Deer Sky, would be welcome as few other dealers will have any of the material for sale. 

Sent you a PM and will get a few wheels packed up and ready to ship

Neal,

I don't use hard Novas, only soft ones but have the metal bonds as well.  I run thru 2-3 sets of Novas a year with all the cutting I do.  Fortunately, I haven't had to replace the sintered wheels yet.

I can ship out 4 soft novas, or 2 soft and and 2 galaxy wheels.  As to the jasper, what types and from where.  I am prepping for the Agate Expo in Cedarburg and 1/2 of what I display must be silica so unusual agates and jaspers always works for me. 
 
Also, any particular grit.  I have 80 and 220 metal bond, 60, 280, 600, and 1200 soft novas.  Let me know what you like and what types of jasper and I get a box loaded up.

Do you care what grits or if its metal bond or nova type.  I have several dozen novas and 5-10 metal bonds available if you are interested.

Almost a toss up on  my vote between the dryhead agate and the lost ledge plume.  Both are excellent stones and show the best these materials have to offer.

Good luck to the final winner

It is a dyed brazilian agate.  The Brazilians dye the agate after polishing and the dye only penetrates about a millimeter or so into the rock.  The finished pieces are loaded into a 55-gallon drum and an analine dye is added of the appropriate color (blue, green pink, occasionally black) and the pieces boiled for several hours and the dye allowed to cool.  the pieces are then removed and washed and shipped out.  I have cut some cabs from druzy dyed pieces and broken slabs that a friend of mine gets.  (He is a major dealer in Brazilian products and get 1000s of pounds of slabs yearly.)  All of the dyed pieces when cut show that the dye does not penetrate all the way thru the stone and experience has also shown that the dye fades in sunlight.

In mineralogy, a pseudomorph is a mineral or mineral compound that appears in an atypical form (crystal system), resulting from a substitution process in which the appearance and dimensions remain constant, but the original mineral is replaced by another. The name literally means "false form".

In the case of Tigereye, the original fibers were individual crystals of crocidolite which  have now been replaces with an individual crystal of quartz.  I thinks this meets the definition.  You could also call it a quartz replacement of cricodolite.

I agree with most of your list

My opinion would be
1.  Mookite
2.  Polka Dot
3.  Fancy Jaster from India
4.  Biggs
5.  Morrisonite
7, 8  Owyhee
9,10  Polychrome or Misty Mountain but Polychrome is more likely
11, 12  Willow Creek

#6 is problematic as there are numerous types of jaspers that could give a cab like this.  Imperial Jasper, an odd Bruneau, are a couple

My work was on a genie and sometimes, just not enough water and instant melt.  I'll get it right sooner or later but I need to cut more agates for the Agate Expo in July anyway so it can go on the shelf for a while.

I hate working amber!  I have some of the Blue amber that my wife bought for me to cut and so far, I have one piece about 2/3s done.  Every time I think I am getting close I get the piece too hot and melt a section and I have to go back and sand out the melted area and start over. 

Love what you have done with the pieces you have.

The long sides where the ends of the fibers are will be darker but the top of the stone and most of the way down the sides will be either the yellow or blue of the original tigereye.  The whole stone will not go black.

Jeff should have a new shipment in from the mine in time for the Agate Expo in Cederburg, WI this summer along with all the specimens that he and his family have been cutting out of this batch.  Wish I could have afforded to buy more material but I need to save up enough for travel money out to the expo as well so we can sell cabs and jewelry. 

I didn't even look at the several hundred pounds of specimen grade nodules they had set aside for cutting and sale.  If you want the contact info, send me a PM and I'll get back to you

I went silver picking yesterday at a friend's house.  He became the exclusive distributor for Coyamito agates from Mexico.  Got to search thru several 100 pounds of mine run material looking for cutting material and pulling out specimen material for Jeff to cut and finish.  Only other trip planned is to the Agate Expo in Cedarburg, WI this summer to sell my cabs and jewelry.

James

I happened to have a chunk of tigereye on my desk at work and took a couple of pictures to better help.

The first photo is a top view of a palm sized piece of blue yellow tigereye.  This shows some of the ironstone matrix that the tigereye seams form in.

The second photo is across the seam showing the fibers of the tigereye.  To show the chatoyancy of the tigereye the slabs must be cut across the seams.  My piece is about 2 1/2 by 3 inches and 1/2 inch thick so the widest cab I can cut from this piece is only a 1/2 inch wide.  If you were to grind down the ironstone on the top of the piece, you would be looking at the ends of the fibers and there would be no chatoyancy at all.

Tigereye must always be cut in slabs parallel to the fibers and at right angles vein of the piece.  If you are cutting across the ends of the fibers, all you will get is a black or brown stone with no pattern and no chatoyancy.  Not exactly sure from your description as to how you have the material oriented.

Good Luck

The first looks like some type of petrified wood.  The second is chop stick agate.  The third looks like some of the other agates from the same area as the chopstick agate.  Some of the material from that area is quite colorful but the better, brighter colors are getting hard to fine.

Happy cutting
