September 2016 Fun Cab Challenge
This is a challenge to yourself... What is the best cab that you can create... posting the results of your creation whatever the outcome.
Theme chosen by prior winner Tommy: "once living"
For a cabochon to qualify for entry it should be visibly verifiable as being a material that was once part of a living organism, or having contained living organism(s). Some examples of valid entries are petrified wood, dino bone, crinoids, Stromatolites, fossil remains, etc.
Rules:
Cabs entered must be at least partially hand shaped or carved and be completed by the last minute of the month in your timezone. They can be started before the month but only finished during the month.
You must have 1 preform / slab / or pre design photo of the rock. You can enter up to 3 individual finished piece (not combined) photos and 1 of the 3 photos will be used for voting to see what cab folks like the most (please note the photo you want used). You can change your photos or improve your cab and place new photos in your original post replacing old photos by the deadline.
Finished jewelry cabs may not be entered (unless otherwise specified by the theme). It is OK if there is a hole drilled in the cab without a jump ring, as long as there is no extras on the rock (wire, chord, etc.)
All entries submitted to this contest must be unique to this competition (not submitted in several different competitions). Any duplicates will not be included in the voting list.
Feel free to share with us the story behind your workings or material.
Also, don't forget to include the name of the material.
If a tie occurs in the voting the breaker will be whoever submitted the finished item first.
Prize : no physical prize, winner gets to chose theme for the month following voting.

So for once I will be first to post! This is local fossil coral from above the arctic circle that I collected a month or so ago. I can't be happier with the results. Verry interesting fact... this rock smelled heavily like crude oil when cabbing on the first 3 wheels. It makes sense since it is an oil rich area but not all of them smell as much. Here is the before photo.  And an after photo.  |

Jet Black ... Whitby Jet - a form of lignite, specifically fossilised Auraucaria sp eroded out of the cliffs and found by beach-combing drifting in the North sea along the east coast. A bit of pitting is inescapable as it runs through the stone. Whitby Jet Rough  Polished cabochon  One on its own  |

Interesting that it has a brown sheen to it.

This has been a great way for me to improve my skills, pitting my efforts against everyone else. This time I picked a rough, cracked piece of petrified fern deeply pitted in parts.  A couple didn't make it, one just popped apart, unseen crack, and the other was thrown across the room, not by me but during sanding on the lap. Still not happy with the shape of the smaller one .  My entry for the month  |

Ahhh the smaller one is better to me! Interesting, I might fix up the shape, small adjustment to the sides to make more even and change my entry. |

Interesting that it has a brown sheen to it. You have a good eye - it has a diagnostic brown streak. If the streak is black, it is lignite - or "sea coal". Jet is strictly speaking a subdivision of lignite. |

OK here is my entry ... once living creatures that settled into a deep marine layer of petrified mud  Not the prettiest cabochon in the world but the difficulty level is off the charts. This material will break at the shells so no dopping - it's a hand carry all the way through. It's also an extremely variable surface hardness so undercutting is an issue - the white shells are softer than the matrix, the blue shells are harder than the matrix, and the matrix is super porous so no polish can be used.   Thanks for looking |

Thanks for participating, challenging oneself is how I learn and improve myself. Interesting material you have. as for the broken pieces superglue them back together and grind / polish the glue until you are down to the stone. Sometimes you can't even tell it was broken when completed. Someplace I may have a photo of some pieces i repaired including one i'm currently working on. you can pm me for some photos. This will be an interesting month, my cab already sold so I can't get more pictures but i'll be making another like it shortly only the colors wont be so creamy. |

I come from coal mining country. I thought Jet was a very hard form of coal sometimes found in the mine. Oh they have geodes in the mines too.

Glenn glennz01 , I think you hit that one out of the park! Very nice.
I decided to cab one up yesterday, just for something to do. Not sure how many pics you require, but here's a few of the rough to start.
Some GA/FL coral from jamesp . This ended up being the back side. This was not a slab, more of a chunk. 
Polyps? Corallites?
Front side, took a bit of grinding. 
Back finished. Can still see the coral, amazing. Would have made a nice front, but shape of the rough was not conducive to that.
Front. I left the hole, because nature is not perfect.

Thank you for the contest, Glenn, and to whomever picked the theme - Tommy? Nice choice.
