I have one to show and one with a question.
First up is a Picture jasper, which I feel came out pretty nice
The Calligraphy Jasper ( at least that's what I assume it is) is the question.
I've read that it doesn't take a polish very well, which I found true enough- one side would polish, one wouldn't.
Not surprising, since the 2 sides are obviously different .
But what I was surprised at, was the chipping on the edge & on the top too. So my question is what's a work around for this type of stone ?
Coat it with epoxy ?
Soak it in the fracture sealer , Opticon ?
Throw it in the don't grind me box ??
Any input appreciated, Patty

With the script stone- I guess the answer would be what do you ultimately want to do with it. If it was a cab just for myself, I would fill the voids with CA glue and leave it at that. Now you know what parts of the material don't cab well.

How funny - Yup - learned something new last night.
The cab would be for me so I guess I'll experiment with things on hand.
Thanks Tela.
Question - I assume "script stone" is another name for calligraphy or are they different??
I have another much redder slab sold to me as calligraphy, and this one looked like a similar thing, but maybe not ??

Wow, love the fossil cab! Color is much like our south Texas Devil's Toenails but your example seems to have more kinds of shells. The toenails seems to be primarily tiny oyster shells while your example appears to be more similar to the tiny coquina clam shells mixed with lots of other critters. Very cool!

BUT, of those types- I get the names mixed up. Like Mel said- it's a fossil stone. The redder one is likely Calligraphy or Script Stone. It has a lot of names. Either/Or, I love yours! |

Thank you Sabre52 for the nice comment & the ID. It's pretty cool stuff, now I just need to figure out how to stabilize it.
It is interesting the names they give some of these.
I saw one called " Clam Chowder Stone:

For girdle chips, I have taped the perimeter (and under the edge) to create a gap where the chip is and then filled it in with a thicker CA. You want to overfill the hole since the CA will shrink up when it hardens. I have learned that CA glue doesn't like to stick to itself, so you kinda get one shot. The leftovers can be ground and polished.

Thanks rockjunquie I'll give it a try. I also have some UV cured epoxy , that does stick to itself, so options. I like having a second chance if I don't fill it enough the first time & it also polishes. If it works well I'll post about it for the record. |

We had a black and white, softer southern California version of coquina called " Pt. Mugu Shell rock" too. I have a nice sawn block in my rockpile. I should have clarified; the Devil's Toenails is not a jasper either but rather a silicated limestone type material. Still takes a good polish but is much softer and easier to grind than a jasper. We do have good examples of chert with various shells but only the Rio Grande chert is very colorful. The rest are usually tan colored and interesting, but not real fancy.

The black & white must be quite striking- love to see it .
You're right it was softer then not to grind - I stayed away quickly from my coarse wheel.
Thanks for the further info Sabre52 |

Patty - Great looking cabs - I really like that second cab (I like "Devil's Toenail"! LOL) and definitely think that one's worth saving...

I'm pretty sure I know where that block of coquina is. I'll try to find it and post a pic on this thread. Should be some toenail rough with it so with it so I'll try to include both.

Agreed Devil's Toenails is over the top.
I saw reference online to other names used, like Clam Chowder Stone.
My husband suggested that whiter ones would be "New England", and of course red ones, "Manhattan". 
Pretty cool now that I know what it is.
The picture jasper photo has such a glare on it, I've gone and checked that cab 3 times with my loop to prove to myself that it was glare !
Photos are such a pain, and it's not even a transparent stone.
Oh well.

liveoak: Here's a pic of the Devil's toenails from the Rio Grande area of Texas vs the Point Mugu Shell Rock Coquina from north of Malibu. This Pt. Mugu hunk is the best I ever found. A bonus was breakfast at Alice's Restaurant at Malibu with all the Hollywood types *S*.  coquina and toenails by lonerider652000, on Flickr |

Very cool. Jealous that you collected them. Here we only have the coquina shells on the beach. The B&W one would look striking when polished ( if it takes one that it) - but cool all the same. Thanks for posting the photos Sabre52Patty |

Just for a hoot, here is the shell rock from my yard here in Texas. We call it Texas Turritella. Sadly, it usually has this low contrast, buff color, and the shells are more scattered than the Wyoming material. It too is a silicated limestone. The point Mugu Shell Rock takes the kind of polish the Indian Script stone does, kind of erratic with mixed hardness. Overall effect is usually more of a satin finish, whereas the Devils Toenails takes a very good polish.  yard shell rock by lonerider652000, on Flickr |

Thanks for bringing this up and Mel out. Lucky you to get his interest. He's our resident expert. |
