After all this, 'bezel', and bevel can be used interchangeably since the work bezel is the older form of the word bevel. Even today, in English, (not American) bezel is more used for a sloping surface such as the bezel around a gem stone. Woody Thanks, Woody, that helps explain why I have been so confused about the two.

This is piece of oval shaped tiger eye I purchased at a bead shop The edge is a darn near perfect round over Its technique I can’t duplicate When I first started the hearts I tried and my results were less than good now I square the edges them off anyone have any tips on how to get smooth round overs? Do you think this tiger eye piece was done by hand ?

Hi Jan This is flat view. It as a with shallow dome The edge is rounded over excellently It’s a technique I’d like to master for the hearts For some reason, and because this was sold in bead shop, my feeling is that they are done on some sort of CNC machine in China. Its incredible the drilled holes and fine polish shapes these bead shops have. Hard to believe thy are done by hand. Anyway I purchased 2 of these oval shape tiger stones. Inexpensive. I’ll cut them and make hearts Actually I have one glued up now and starting 2 /grind/polish it I think it going to come out wowzer mostly

Hi, Ed, not sure either how the edges are perfectly rounded. Very nice beads though, and looking forward to seeing them shaped into hearts.

Hey gr! I cut that oval in half at 13.5 degree by eye it went off on a tangent but the flipped pieces made a nice heart shape well a little bit lopsidEDmostly
I should have used a square & compass ;D mostly

I'm the worst person at misusing terms LOL!! I bevel the bottom edge of my cab to keep it from chipping. The girdle is the flat edge of the cab but then I do another bevel ( ) down to the top edge of the girdle to start my dome. Now I'm curious if I even said that correctly!?!?! Krystee I'm not sure I understood your comment but I was taught to cut the bottom bevel and girdle. Then cut a bevel above the girdle. Then cut an overlapping bevel above that at a steeper angle. Continue cutting steeper bevels until they meet at top. Then grind all the edges off. HA! John, what you said is exactly what I was trying to say regarding the bevel above the girdle (or...how I bevel down to the top edge of the girlde).... I just can't explain things LOL! After all this, 'bezel', and bevel can be used interchangeably since the work bezel is the older form of the word bevel. Even today, in English, (not American) bezel is more used for a sloping surface such as the bezel around a gem stone. Woody But then again..... according to Woody, the bevel above the girdle could actually be called a bezel since that's the slope! (Shaking head...), I'll just keep cabbing and quit talking ;D

I call it the eye of tiger heart I don’t believe this tiger iron occurred naturally this way It must be recon-figured or reconstituted scrap tiger iron to get this effect ? bead shop Its pretty cool and I’ve been wearing it Maybe I should use a plumb line to snap a diagonal line across the oval, gr Thanks for the interest Jan !

Do you think this tiger eye piece was done by hand ? Ed... to get that 'round over', you push the side of the cab into the grind wheel exactly level... then SLIDE it up, then SLIDE it down, in 1 motion a few times, curving your hand under the piece. Doing THIS is how I lost most of my fingernails, because it's very easy to trap your hands nail down under the cab without realizing your fingernails are in contact with the wheel. Looks like this: Here's the cab (this is a piece of Daniel's - Deb123Redux - piece of royal velvet obsidian he sent me in trade last month:)): It was a relatively thin piece, so I was terrified I'd ruin it, but wow... what a stone!

Ohh... I see what you mean Ed!! Getting that rounded curve all around the piece. I have to admit that on the rounder part, it's more challenging, but going over and over it helped a lot. An easier way to get that effect is to round it enough that it's close.. and then use Krystee's method for Obsidian in the vibe tumbler. I had to do that with all the final polishes on my cabs, because I have a gap in grinding wheel from 1200 to 50,000. There's no question you get a better hand finish, and tumbling cabs is nerve wracking because of the possibility for cracks and gouges in the pieces. At the rock club's machines, from final shape to fully polished is very fast. Via tumbler, it's checking every piece every hour for 4 days almost around the clock. I'd way rather do the hand polishing, without risk of complete destruction to the stone (and I've gotten hairline cracks in some beautiful rocks in the vibe), but I don't have the equipment at home. I'm just happy that I can rough shape now:). That said, for uniform rocks like obsidian, the vibe may be easier to round those edges. It's the composite rocks that don't do so well in the vibe, so maybe it's worth trying for some of them to get the edges. But you don't need the edges, your hearts are gorgeous as they are:). Krystee, that is an AMAZING piece of velvet!! Daniel sent me some gorgeous pieces, but it's still hard to believe how much more of a stone comes out when fully polished! You could see there was beautiful color, but I didn't expect to see this much color at the end. The more polishing I did, the more bug-eyed I got! LOL! Daniel has some INCREDIBLE specimens of rocks... but you can tell that by looking at the slabs he's posted. He's a perfectionist in every way, with immaculate taste! This was the smallest piece he sent, and he had partly shaped it already. I scratched it up badly when testing out the 14,000 wheel, but it was thin, so I was so afraid to take more off. Still, I am shocked at how much color was in it, and I suspect that the thinness actually helped show the colors more. Here it is, cropped out of the group shot, as with many of the cab sized pieces, I didn't do a whole lot of grinding, Daniel had already sized and roughly shaped it, so can't fully take credit for the shape:

Well it the next step I need to do in heart mastering I started trying to contour the edges of the heart with so so results some material are easier than others of course but the heart is such picnicking shape that any deviation shows so now I square off the edges I really like the look and it makes shaping the heart easier, bold with a distinct profile of course, I free form trying to create a distinct shape and that complicates matters plus it 2 pieces trying to get them to center then there the out of balance hanging problem and other problems o whoa is me the happy heart guy mostly

Oh Ed, your hearts are gorgeous, you don't have to change anything! Not sure why you'd even consider rounding the edges, your flat edges give your hearts a very nice clean edge.
I just commented because you said that it looked like it was machined and not done by hand, so I was just showing you that not only can it be done by hand, even a novice like me can do it... with lots of experience, I'll bet some people can do it flawlessly and very fast too. But it's not something that you'd want to do in every situation. Your hearts are perfect just as they are!!

My heart is perfect also but nobody believes me. They all say "na, its all in your head, well mostly". But that can not be, I always have my head in my ass. So where does that leave my heart. NO NO NO don't even go there. wampidy@heartinmy.com
