Zebra Jasper

I'll be happy when I'm done with this stinky stone.



100grit grind --

Well, the stench has gone from musk, mold, and rot to all of that plus rotten eggs.

A nice winged horse in the center of the larger stone though.



======================

220grit grind --

Only stinky when I smoothed the bottom. A very strange stone.



In the interest of saving time I'm not going to take pics of the 220 and 600 grit sandings.

======================

360grit sanding --



======================

These will have to wait until the 1200 diamond grit comes as the tripoli chewed into the one I tried. Not as bad as the speckled one I posted a while back but annoying nonetheless.

======================

1200grit Polish --

Gold Sheen Obsidian

The amount of chipping the 100grit wheel caused on this stone has me thinking I'll do as little work as possible on that wheel. I think I'll work sort of close to the bezel and just to the outer top marks.



100grit grind -

When going down to the bezel and the outer top lines I had no chipping. So I decided to finish the rough forming.

What I was unable to capture in a pic is how the banding can be seen at different levels in the stone and how it stands out when the light catches the sheen.




======================

220grit grind -

In showing these to my wife just now she said "I thought you drew those lines on". I said "no". And then she goes "ooooohhhhh!".

Women bring color to an otherwise gray world.



In the interest of saving time I'm not going to take pics of the 220 and 600 grit sandings.

======================

360grit sanding --

I wish I could capture the 3D shimmering bands. Very nice.



======================

Tripoli shined them up nicely. However, a number of bunched scratches showed up after polishing. I've seen these before on other rocks and I'm not sure if they were missed on the sanding steps or I polished too fast and too dry and caused some "flow".

Regardless, I'm going to polish them with cerium oxide now in an attempt to take care of those scratches.

======================

Well, that didn't get rid of the groups of scratches. My wife tells me she can only see them if I point them out and she looks real hard. But they stand out to me. Like a huge neon sign is pointing them out.

So I took them back to the 600grit sanding and hunted the things down. Based on how hard they were to get out, I suspect they showed up much earlier. Possibly around the 220grit sanding. But what stands out on polishing is *very* hard to see earlier on.

On polishing with tripoli for the second time there were cloudy areas (not full mirror shine). Not sure the cause of that, but I'll try another go with the cerium oxide.

======================

They're a bit better. One still has some faint scratches and some dull area. But the other one is OK.

Tempted to put up this pair with the contrast bumped up in order to give an idea what the gold sheen looks like.

Pic below was taken dry after preforming on the 100grit wheel. The small one on the right shows how small I would have had to resize if I didn't decide to make the other side the top.



100grit grind -



======================

220grit grind -



In the interest of saving time I'm not going to take pics of the 220 and 600 grit sandings.

======================

360grit sanding --

Interesting colors are starting to show up in the stone.



======================

These will have to wait until the 1200 diamond grit comes as the tripoli chewed into the one I tried. Not as bad as the speckled one I posted a while back but annoying nonetheless.

Christmas Rocks

The slabs have arrived.

I was expecting them this past Thursday but no. Not the fault of the ebay seller, just USPS was running slow.

I'll have to move faster than I had hoped but... ehhh.

I've also gotten around to ordering 1200 and 14K diamond grits which should show up next week. What lit a fire under my rear on this is if any of my Christmas rocks have soft areas that the tripoli might chew up.

Let's have a look-see. These photos are done outside of my box so that I can get a more vertical view. Granted, as I wet them I could not get a 90 degree shot on them without major glare. I probably should have used the photo box.


Wonderstone Rhyolite --

I like the patterns on this but there are many cracks that meet the surface. As the cracks follow the outsides of the major patterns I should be able to work around them.



Here it is marked. My wife found the "feather" in the top round and the "sunrise" to the left of that. I found the "gas flame" on the right.

This stone might be trouble. The cracks appear to be cleavage and I've had a small piece pop off in moving it around.



This stone had some chipping and sloughing but nothing to effect the cabs.




Leopardskin Jasper --

I like this one. Should make two nice stones.



Not so great pics of the mark-up. One with too much flash and the other without enough light. Because of the patterns I'm going to have to cut the top of each of the two cabs from different sides of the slab.



This stone was a pain to trim and I had some sloughing that forced me to resize one of the cabs (on the left). I will probably use the flip side so that I can save some of the material and have a bit of a pattern.



Mexican Crazy Lace Agate --

I very much like this one. There are some cracks that meet the surface and a couple of cavities. But it looks very workable.



Oh this is a lovely stone!

Dragon's head.



Sorry about the focus on this one.



My beautiful stone had a major issue. I began to trim in between the two larger cabs and the stone came apart. A small chunk was taken out of one of the larger cabs and a large piece fell away from the other large cab (forcing a resize). And the material under the chin of the dragon's head fell away as well. But all might not be lost on that. How it fell away I may be able to save the head but it won't be symmetrical.



Gold Sheen Obsidian --

I like this one as well. There is a nice sheen when it is held at a slight angle. If the material was thicker I'd try to orient it to flash when viewed directly, but still I nice stone all around.





Very well behaved stone on trimming. It did have some chipping but nothing major.



Rodeo Lace Agate --

Not as keen on this one. Too busy looking. But the womenfolk in my house like it.



Sorry about the focus on these.



Another well behaved stone. Did have a good deal of material slough off around the thin stone. But that was expected as it was near some fissures.



Zebra Jasper --

Not too hot on this one either. I only like black and white things when they have very interesting patterns. I'll try for that when I mark out the templates. Seems there was some leftover oil on the stone from when it was slabbed. But I think it's OK in that the wet view can be seen.



When marking this one up I noticed that the white areas have white reflective chips throughout (about 1mm x 3mm).



This stone smelled of the swamp when taken to the trim saw. Very odd.



Opalized Petrified Wood from Wyoming --

I tend to prefer play of color in my opalized items but the womenfolk insisted.





A good bit of material sloughed away from the smaller cab and I had to resize.



Opalized Petrified Wood from Arizona (free gift from seller (thanks natures-gifts2000!)) --



I may be able to get two stones out of this one.



I did have enough material to cut another cab.



======================================

Think I'll do things a bit different this time around.

From here I'll open a post for each type of material to cover the steps to polishing. As time is an issue, I may not take pics of every step.

Random bits

Fighting an endless low grade cold. Need to get the leaves up before they kill the grass that I paid a premium to water in the near drought that hit my area.

fun fun fun

================

Came across a how-to video rental site on Instapundit -- SmartFlix

It is super cool!

Many how-to videos on many different subjects. What stood out to me is that in the jewelry making section they have all of Alan Revere's goldsmithing videos. I had seen those videos on Revere's website but decided to put them off as they go for $50-$70 each. But one can rent them from SmartFlix for $10.

Nice.

================

I came across TeraPeak a couple weeks back. Started to research cabochon sales and hit some facts that forced me to rethink some things.

I decided to find what material sold well as cabs and compare that to the price of rough.

Well agate, jasper, opal, ruby, sapphire, emerald, as well as transparent material that is normally faceted.

The cabbed faceting material (especially spessartine) really threw me off. But after not finding any cab rough in that material of decent size, I could only assume that faceters were just trying to recoup some money on pebbles in a parcel. Buying facet grade rough to cab would be foolish.

This leads to agate and jasper. What really sells in those materials are fancy shapes and real interesting patterns. Real interesting patterns tend to show up in costly rough. At this point I'm not prepared to lay out large sums for rough that I have not proven myself on. As for the fancy shapes, I'm not interested in cabbing in and of itself. I'm cabbing to #1 make nice things for my daughter and #2 make things to sell in order to buy faceting equipment. I view learning to make fancy shapes that are better than what the commercial houses are putting out as a diversion to my near-end goal of faceting.

Then there is opal. Opal looks to be a good money maker. However, the real good cab material comes from Australia. In order compensate for the large shipping cost, I'd need to buy a large parcel. Most dealers recommend $50-100. Again, I'm not prepared to lay out large sums for rough that I have not proven myself on. I've seen smaller parcels offered by vendors in the US and Canada, but their parcels are smaller and for around the same price. I think I will come back to opal if it is taking a while to work up the money to get the faceting equipment.

Emerald does well as cabs. The best cabs look to have been cut from facet grade parcels. I've seen what looks to be OK cabbing grade emerald, but there is a lot of very low grade rough out there.

That leaves ruby and sapphire. All the materials mentioned above are in items selling for under $2, but for some reason sapphire cabs are nearly all under $2 (at least from the 30 day free info from terapeak). I don't understand why that is but it is. Large ruby cabs (8ct and above) look to sell for $10-$25. Looking at corundum rough, there is a great deal of low grade material as well. In poking around I found some rough that would make two 10mm ovals or rounds for about $10.

So, if I want to enter the market cheaply ruby looks like the way to go. However, if I can get a $20-50 return on an $10 outlay for around two hours of work -- I'm looking at $5-20/hr.

(Forgot to mention that jade is another low cost entry material that performs about as well as ruby for the same cost in rough)

Considering that doing more than five stones a day burns me out quick, that doesn't look like the best plan.

This had me questioning my stance of only buying the faceting equipment through the sells of cabs. My original thought along those lines was that I don't need yet another expensive piece of equipment that I've lost interest in. I want to prove to myself that my interest, time, and money are being well spent.

But, I started looking around on terapeak for faceted stones. Well, just like in cabbing, better rough and larger 5+mm end stones give a better return.

So, jump right in and spend a ton of money on rough? When I have no idea if I can cut things people will buy?

No.

I have no past experience making money with hand skills. Yeah, I do little things around the house, but nothing proven.

So what to do?

Well, I had thought about goldsmithing and gem setting as something I'd do after I'm faceting. But I'm thinking I may start practicing with base metals now and then move into silver and gold.

I'm thinking this practice will allow me to avoid spending money on settings/findings and allow a greater return.

In the end, from what I read, I need to be able to get a 20-30% return. Bought settings and findings take away from that, but the additional labor of making the settings might not balance out.

Fascinating stuff.

===========================

I think I'll rent McCreight's video from smartflix.

I had been thinking about picking up his "Complete Metalsmith, Professional Edition" but have held off due to a few of the excerpts I found. They seemed very brief. I later heard about the book he edited for Erhard Brepohl, "Theory and Practice of Goldsmithing". Reviews of that book indicated that it covered the same ground as Complete Metalsmith as well as other areas. Also it was more in-depth.

I'm thinking the video will help me decide which book I want to go with.

As for working stones, my wife has bought a bunch of agate, jasper, and obsidian for me to cab as Christmas gifts. I'll play with the found stone until that arrives.

Starting in January sometime I think I'll start cabbing jade and ruby to sell. After I get around 100 feedback I'll start tossing star ruby into the mix.

To avoid burnout I'll try doing 2-3 stones a night. I'm thinking that should be few enough and I'll have a chance to test it out once the Christmas rough arrives.

EUR/USD - Watching
GBP/USD - Watching.
USD/JPY - Watching.

USD/CAD - Watching.
EUR/JPY - Stopped out on short 166.91. Profit diff 488.

That test showed that a limit needs to be in place. That could have been 300 points better.

Update:

Held off entering usd/cad too long. Had seen short upswings in the past and mistakenly thought that they would be large. If I had followed my signals I would have entered 11/11.

USD/CAD - Entered on long 1.0021, stop 0.9467, limit 1.0465
Been dragging lately. Temp has hopped around a great deal and is messing with me.

My daughter picked the group in the lower righthand corner for the fifth run.

100 grit grind --




All of these are quartzes. The little one has a few large clear areas.

All three larger stones developed cavities. But I think I can work around all of them except on the red one.

I found that disappointing as I liked the iron stained one with its deep red "veins". The yellow brown one's cavities along the bezel might cause some problems. I don't know.

Not sure why blogger is making these two pics as downloads when you click on them. I set up the links like the other pics. Strange.

========================================================

220 grit grind --

Need to finish this batch before the Christmas stones come in.



========================================================

In an effort to save time I went through the sanding and polishing without taking pictures.

I'll put the end pics up later tonight or in the morning.

Something new I tried - rounding the bezel. Going through terapeak I noticed that all the ruby and jade had rounded bezels and I thought I should learn how to do that.

Thought I'd try the rounding on the 360grit step. No no no. It will need to be done on the 220grit sanding step.

========================================================

Polished -

Running late and couldn't get a good pic of the large white quartz. The brown quartz had several cracks that reached the surface.
