It's good to have you back Kris. Unfortunately I'm all to familiar with those dramas. Hope you're getting on top of them!
I'm confident that any good doctor would recommend a regular dose of rocks or they're not worth their salt.

Barely perceptible at this magnification and as Fossilman says it's healed anyway. A product of perfectionism ... a non-issue imho.

Lovely cabs! My inclination is to go with zekesman, however I may be a little more diplomatic and suggest that rockjunquie might be on to something... I reckon a bit more of a balance would be good. The light-box images appear to lack a little in front-illumination. With a tweak to your lighting then the light-box could have it. Until then, the sun-lit stones are showing greater depth.

It looks very much like Azurite / Cuprite to me... source

Yes, yes and yes in that order.

More cabs to come, but I'm not cutting much at the moment / for the foreseeable due to domestic issues.
I collected a few with the idea of maybe tumbling them, but I just turn out tumbles and wish they were more amenable shapes so I'll probably cut some as and when.

Has anyone looked into auto body repair shops as a possible source? I believe that the rarity of Fordite stems from the way that changing technology i.e. masking off and sprays have eliminated the 'environment' of formation. I'm not sure spray-paint will cut it (pun intended) for hardness; surely the repeat baking of enamel paints is where Fordite gains the material strengths that make it a viable lapidary material. I could imagine that Fordite can be created, but that the costs for repeatedly cooking will exceed any 'value' to be gained. It would only work on a huge scale or as happened as a by-product of another process where the process is financially fulfilling. But I'll celebrate your successes if you achieve it and don't let it be said I'm a nay-sayer. I wish you all the best & watching with interest.

Don't hold your breath, as Zoran was last online just over a year ago - on 22 April 2016 It would be good to find out though...

Yay! That's a beauty. (Ok so you can see some errors, but at that magnification you're bound to)

Here's a piece of chlorite facies metamorphosed lithic greywacke slate and Quartz from Ingleton. The greywackes are turbidites that formed from submarine avalanches along the north-west margin of a land-mass. In this case, one that existed in the geologic past, known as the Eastern Avalonia continental shelf, bordering the Iapetus Ocean ( source). Originally these were identified as coming from the Precambrian (giving their name to the Pre-Cambrian age the Ingletonian) but were then thought to be Ordovician, from the Arenig. The pendulum of opinion swung back to Precambrian and in 2008, back to early Ordovician. This to-ing and fro-ing might relate to the possibility that Pre-Cambrian and Ordovician are interleaved. The British Geological Survey is of the opinion that on balance the rocks should be considered neo-Proterozoic. Phew! Glad that's sorted out (for now ) The following rock is from the area known as the Yorkshire Dales, a national park, home to the amazing Thornton Force... Author: Val VannettThe slates are shown as the lower series in this Ordovician - Carboniferous unconformity resulting in the spectacular waterfall. Their age is now thought to be Arenig, however the previous estimation of the age of the rocks provided a sub-division of the Pre-Cambrian known as Ingletonian. It is slightly ironic that the early Proterozoic rocks from Ingleton have now been shifted out of the Ingletonian epoch. hmmm. Of course collecting in the national park would not be considered good form. Luckily the planners have permitted a significant roadstone quarry to be located just outside of the national park: This is home to some green-grey continental shelf turbidites - greywacke that have been metamorphosed to green-schist facies slate then occasionally vein-injected with quartz. The quarry has only a few years of life left in it and I don't know of any other polished cabs from this location (but then who polishes Greywacke)? Author: Clem Rutter A particularly good description of the local geological features can be found here. Back to lapidary and the evolution of a piece of rough through to polished cabochon: Greywacke slate and quartz

Go on then?!
Tumble finished charoite and wonderstone is my guess...

You can't pick another one up without having to put one down.

That's a train full of rocks pulling out from Donnie station! My favourite? That's easy ... err... the Ozzy Variscite or the Poppy Jasper; maybe the OJ or the Dino bone and no's 3 or 4 of unknown and the Carey except the Mystery Mountain has it hands down... You've been busy!

This is terrible. There is no reversing time and no undoing what has happened ... but it must not be allowed to happen again.
