Good one Jeff!
That's what emeralds wish they looked like.

Done this morning. I usually do not cut checkertops, but someone told me I had to. 10X15mm.
Pink YAG, a quickie practice piece before cutting the order stones.

Placed on bottom of styrofoam coffeecup, taken in open shade.

Yes, beautiful stone. Being YAG, I bet it really sparkles in some light.

Gee... I wonder what it was polished with? :smt017

Thanks. I look at the photos people are uploading and blush in shame. Here is a person whose father went to Art School on photgraphy scholarships, who grew up with a darkroom in the house, and cannot seem to get a decent picture with a Canon digital camera today!.

Here is another, but still ghastly..

I love YAG. Too bad it's not worth much any more, but having more than a dozen nieces, it's NO trouble disposing of it. This was a practice run for a couple of these I have to cut. It was also a test of a new lap alloy.
Cut 360->3,000 BATT, 60,000 on "BAT2".
The new alloy is being evaluated by some serious high volume cutters at present. It is intended to be a BA5T equivalent, but at a regular BATT™ price. Some of the exotic alloy components in the BA5T alloy price it out of the range of all but the commercial cutters. If it "Flys"with them, I'll announce it on the BATT Page. If it does not, I will just have to go back to work on it, but so far it is looking good.
That said, this was not a speed trial, as I had not cut a checkertop in years (Decades??), so it took a couple of hours to cut the thing.

Pears are a lot of work ... Good job on that one above.

Well, this is my latest creation. All concave facets. Just when I think I'm over the concaves, I get motivated to cut another one. The material is a piece of Garnet that I picked up in Idar Oberstein several years ago. It had been sitting around long enough and his time was up.
3.54 cts. 8.8 mm

Holy cow, garnet?! Something tells me Idar Oberstein is the best place to get rough? I wonder if there is a better show to get rough? Not Tuson from what I gather from Jeff Gram's site. Rock

One would think, now that I am not wasting my time with a day job, that I would have gotten around to curved faceting: I have the machine tools to quickly make a mandrel motor adapter, but sadly, it is still in my "List of things to do someday", like the vague plans one has to master another language, or the violin.
The optics of the process intrigues me. The light return cannot be coming from the facet itself, because of negative power, but from the intersections of the facet. Being intersections of cylinders , planes and cones, just figuring out how a cut works could be a project in itself.
Imagine the raytrace program! :?

Same here. I bought my Batt several years ago (back in 2001, I believe) and have been a faithful user since. That's one mighty-fine alloy you've created sir :wink:
