  1. I want to thank @AncientEarth for the wonderful prep work on this specimen. I'll be excited to pick it up next month. Aaron does really good work and I will definitely use him again in the future.
  2. Is this real? Can see a line seperation
  3. I saw some was sold in an online fossil retailer, and some are for sale in two other ammolite retail shops. Is there anywhere else I could obtain specimens crafted by S. Carbone, if not directly from him (and preferably online)? Also, ammolite grading system are quite confusing, I tried to read "Spring 2001 Gems & Gemology", but I still can't quite grasp what features would separate them to different grades, e.g in Korite's collections, I saw some multicolor, high saturation specimens graded as A whist Lower saturation specimens where some colors are difficult to notice are graded as AA (I know there still isn't a universal, agreed upon grading system for ammolite gems, but still...) . I know this post isn't quite fitting for this forum but I want to seek help as far wide as possible. and for reference, what grade would this be?:
  4. Hi everyone, I am new to this forum and have been loving it. I found a very fragile ammolite preserved in mudstone (I believe) and I want to seal it to preserve it and prevent it from falling apart. What can I use? Can resin/epoxy be used?
  5. Hey everyone, I’m new to the forum but loved fossils all my life and recently got into building a nice collection. I have a chance to acquire a very nice Ammolite Ammonite at a decent price. I’m curious though are they more desirable in or out of the matrix? The one I’m considering has lovely colors including blue and purple and is out of the matrix. Was just curious before spending that kind of coin if I should consider in matrix. Thanks in advance! Lee

    Ammolite Jumble

    Here is an aggregation of rough ammolite. It rests on the vanity of the guest suite's bath in Palatial snolly Manor. The chunks were obtained from a Canadian jewelry producer, specializing in ammolite items. My hypothesis is that the ammolite layer on these pieces was judged too thin or fractured to warrant cutting as stones for jewelry. The ammolite remains backed by thick ironstone and the pieces have been heavily consolidated. Given the varied angles of their faces, they make an ever shifting display as one moves about the room.

    Polishing Ammolite

    I stubbled on a few small pieces of ammolite while out fishing. I have searched the internet and this forum for information and have come up with several different ways to clean and polish ammolite. However I have not been able to find a detailed process from start to finish to get ammolite looking it’s best. I know there are different qualities of ammolite and some require little to no work but mine needs some work to get it to look good without getting it wet. I have tried sanding for quite a while up to 600 grit paper. That’s the finest I could find but now have found up to 3000. Should I just keep going with the sanding? Is there polishing or buffing to do after the sanding? Is there an epoxy to put on after to keep the wet look? Any information would help and I thank you in advance. I just want to do it right the first time so that I don’t wreck it or have to go back and try to strip off something I put on.

    My crystallized fossils

    Here’s my crystallized fossils, enjoy!! All of them so far Ammolite from Alberta Ammonites from Madagascar
  9. I've posted some pictures of the ammonite I bought and want to polish. If you look at the third picture, (ammonite 2.jpg), you will see that on the ammonite some rainbow color resides. I want to make the whole ammonite that color. Is there any way to polish it to make the rainbow show more? Correct me if I'm wrong, but that rainbow color is fossilized mother of pearl aka Ammolite. Does anyone know the following? If you could answer, that'd be a big help. Thank you for your future words! Any suggestions welcome. You'll never know what will work. The best way to clean and polish the ammonite to make the ammolite show and without breaking the fossil. A way to preserve the color when and if I polish it. Thank you so much, everyone, for your future ideas!
  10. Hello everyone, I recently received this large 14inch ammonite and the shipper had no care in the world to put even an ounce of protection thus this is the result I'm not experienced with much prep and not confident superglue would cut it so what would you all recommend to help repair this specimen as well as clean off some of the dirt/dust layer coating alot of it?
  11. Hi decided to start showing of my collection so I started doing them in individual post here are ammonites/ammolite enjoy!!

    Ammolite with trilobite??

    Ammolite with trilobite? It can be real?
  13. We found a variety of nice fossils on a recent visit to the cliffs on the St Mary River in Southern Alberta. For early January in Canada, it was like a summer day. It took me about 15 minutes to find a 100 pound concretion and another 20 to dig it out. Then a great deal of grunting and groaning to get it up the cliff on my back. It turned out to be a gem ball. More pixs of the gem when I clean it. We also found a nice placenteris meeki suture fossil, lots of gem, and one interclare. The pictures show the cliff, uncovering the fossil and a few other shots of finds. other pixs follow

    Natural Iridescent Ammonite Ammolite Specimen Fossil Madagascar, probably Mahajanga Province Early Cretaceous period - Early Aptian (about 115 million years old) Cleoniceras is a rather involute, high-whorled hoplitid from the Lower to basal Middle Albian of Europe, Madagascar, and Transcaspian region. The shell has a generally small umbilicus, arched to acute venter, and typically at some growth stage, falcoid ribs that spring in pairs from umbilical tubercles, usually disappearing on the outer whorls. Ammonoids are an extinct group of marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs are more closely related to living coleoids (i.e., octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species. The earliest ammonites appear during the Devonian, and the last species died out during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and it is often possible to link the rock layer in which a particular species or genus is found to specific geologic time periods. Their fossil shells usually take the form of planispirals, although there were some helically spiraled and nonspiraled forms (known as heteromorphs). The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns. Pliny the Elder (d. 79 AD near Pompeii) called fossils of these animals ammonis cornua ("horns of Ammon") because the Egyptian god Ammon (Amun) was typically depicted wearing ram's horns. Often the name of an ammonite genus ends in -ceras, which is Greek for "horn". Ammolite is an opal-like organic gemstone found primarily along the eastern slopes of the Rocky Mountains of North America. It is made of the fossilized shells of ammonites, which in turn are composed primarily of aragonite, the same mineral contained in nacre, with a microstructure inherited from the shell. It is one of few biogenic gemstones; others include amber and pearl. Ammolite comes from the fossil shells of the Upper Cretaceous disk-shaped ammonites Placenticeras meeki and Placenticeras intercalare, and (to a lesser degree) the cylindrical baculite, Baculites compressus. Ammonites were cephalopods, that thrived in tropical seas until becoming extinct along with the dinosaurs at the end of the Mesozoic era. Other fossils, such as many found in Madagascar and Alberta, display iridescence. These iridescent ammonites are often of gem quality (ammolite) when polished. In no case would this iridescence have been visible during the animal's life; additional shell layers covered it.
