rockjunquie if it is legal where you live, you might consider CBD gummies in the very low % THC flavor. According to my son who worked the weed industry for awhile, zero THC is ineffective for the most part, but the stuff with just a tiny bit of the THC is supposed to be good for focus, as well as pain management. Keeping in mind that AFAIAC it is a personality type that todays society rejects, and not a "diagnosis", along with most of the "autism spectrum". I believe it is the Japanese who think that most of our "psychiatric" issues are just personality issues. |

If I was a lapidarist, I might know what a cabochon is. I cut, grind, sand and polish rock. From what I see on Etsy, a cabochon is whatever the seller thinks it is. The height of the dome is a function of how thick the preform is and how deep is the pattern. The main reason I make a girdle is to protect the shape drawn on the bottom. When I cut into the girdle, I can always lower it. I found a trick that works for me. My sides are not 90 degrees to the face until the dome is done. I then align the sides to the face. by rotating the side against the wheel at 90 degrees. My girdles are smoother and more even and a lot of problems where the edge meets the face go away. I do low domes and high domes the same way. Flat tops/buff tops are made by treating the entire edge as a girdle. The only other issue is scratches. Less problem with scratches with a domed cab. I figure 8 the face against the wheel and check for scratches before going to the next grit.

I'm still looking for the other book. This one is from 1940 and shows before girdles.   |

Not adhering to standards and all over the place like an ADHD toddler is kind of the story of my life. Funny that I spent 40+ years manufacturing and fabricating to rather exacting standards, guess this has been my escape. Sitting on my butt today finishing my recovery from non coufid crud (took the test). I'll go away now. LOL! Don't go away!
I hear ya about the ADD thing. I have it. I used to be medicated, but now you have to jump through ridiculous hoops to get medicine, so I do without. Which means I'm all over the place, too. Right now, I am knee deep in some wrapping experiments. Can't stick to one. Pickle takes too long, so I start another project. Works for me. LOL! We have the crud going around, too. Get well soon!
Story of my life, too. I so easily get distracted, don't finish things. Get bored and move on to something else. Was never officially diagnosed with ADD/ADHD, but as an adult, I recognize the symptoms. I'm sure a few/some/MANY would disagree with me on this, but I have come to think there are a lot of misfits, or perhaps I could say "special" RTHlings here. I believe being special totally lends itself to the creativity of people in this pursuit. We think outside the box, are very creative, and have our own ways to do things. (Just saw several posts over the last couple days where people posted exactly that! "I don't follow, I do things my own way," etc. That's great, nothing wrong with it. You be you, do it your own way. ) Nothing ventured, nothing gained. I think we also tend to throw caution to the wind, and just jump right in with both feet. We find new or different ways to accomplish things. It's a win for all of us! |

Good idea, rockjunquie ! Buff tops are totally flat - you work the top just like you'd work the back of the cab if you were polishing the back. Very low domes may be 1-2 mm or so thicker in the middle of the cab than the girdle height. " Buff Top" or "Buffed Top" is one of those terms that seem to have two or more meanings. I believe it was originally applied to gems with faceted pavilions and flat or curved cabochon crowns. I thought I had an image or two of such a cut but my files are so messed up I can't find them. I know I have several stones cut that way -- usually the result of a great faceted pavilion and a screwed-up transfer while attempting to facet a stone  You're correct, Rick. We did a buff top faceted opal for engagement ring for a guy in Texas. Buff top cabs and faceted stones are two different beasts.  |

We did a buff top faceted opal for engagement ring for a guy in Texas. Buff top cabs and faceted stones are two different beasts.  Touche! But is the stone I described faceted or is it a cab? Maybe it should be called a Janus Stone for the mythical god Janus who had two faces. The late Larry Woods, a prominent gem dealer, named the cut a "Cabochet." I get the "cab" part but the "ochet" confuses me. Reminds me of Cabaret. As for me I think I'll go cut a carbuncle. Anyone know what that is? |

Anyone know what that is? Is that where ends are left rounded over so that the girdle is arch shaped? ... Or, as in gem cutting, is it a big, high domed gem? |

Or, as in gem cutting, is it a big, high domed gem? It could be big and high-domed if it's hollowed out. A carbuncle is a hollow cabochon and is cut mainly to allow more light through dark materials like almandine garnet. People love the color of dark red garnets when light is transmitted through them but if cut solid they display almost black. It's an old-fashioned and difficult cut but a few are still supplied from Germany for sure and maybe from elsewhere. |

I didn't know it was hollow. That's pretty cool! |

Had never known it was used to describe a high domed, hollow cab. Thanks for the education, Rick gemfeller |

I don't do doublets but have the quartz slabs if I care to and have been to a doublets class.

Well, this didn't go as planned...  I'll try to work something out as I have time. I'll have to go digging for pictures.

I actually thought there might be a little more participation. I'll get some pictures together in the next day or two of the following: High Dome (with measurements) Low Dome (with measurements) Inside Curve (probably wouldn't be the best one to provide an example...but I'll see what I can get a picture of...) |

I am learning a lot from this discussion. So, this would be considered a buff top cab? Height 36mm Width 36mm maximum Girdle 3mm Crown 6mm      |
