A new image of some detail of the same specimen will be posted here every day or so until someone guesses it correctly or the thread dies from lack of interest. Keep scrolling down in this post to see extra images as they are added.
Bonus points for information on any inclusion type shown.
Winner gets to put up photos for the next challenge?
For whatever reason, It's proved impossible to add further to the original 'Guess the Gem' post. Rather than wait any longer, I'm placing here the eighth and final clue that should draw together several of the others (hint) here in this a second post.
It's mildly disappointing that no one yet has been prepared to make a guess as to what the gem is but, I'll guess that is more down to the very small number of members who view posts here with any frequency. AIUI, there are some 4,300 registered forum members, of whom only Gem-A paid-up members have forum write privileges (>3,000?). At the time of writing, this thread has had 35 views, of which I think 12 are mine, creating, adding clues and struggling with recalcitrant software. Of the other 23, I'll guess that >10 are repeat views by others, suggesting that around (max) a dozen persons have been curious enough to look in. Never mind, the challenge remains open and, hopefully, sooner or later, someone will guess it successfully.
Some further information that might be marginally helpful The specimen was found by a local rock-hound whilst beach-combing on the shore-line of Lake Michigan. The finder, not knowing what it was but finding it to be an attractive water-worn pebble, attempted to tumble polish it, along with some other gleanings from his outing. In doing this he caused differing types of damage to the crystal as can be seen in the images put up here.
Anyway, I hope that, in due course, this thread gives at least one or two people a little light entertainment. Should it do so, it will have been worth creating it.
Thank you for your interest; it's a bit of a sad story. I set this thread up about 8-9 months ago. After it had been viewed about 100 times, I realised that at some point an administrator had changed the the filename details for the photos so that the ID of the gem was disclosed, thus making the whole little exercise pointless My fault for relying that the abbreviated visible file name protocol would never change. So what to do? With so many people having by then viewed the thread, simply editing out the tell-tale information would have done no good. It seemed to me that it would be best to leave the text unchanged but removing the photos, this being a clear signal that something was wrong (like a ship flying the it's national flag upside down) and provoke some enquiry, be it from site admin, moderator or a fellow member. I fondly imagined that this might follow in a few days or even a couple of weeks but it has taken over seven months(ISTR) for such an enquiry to come along.
All a bit of a shame really. Like most others, I imagine, I think that IDing gem rough from photos only and without test results can be little more than a silly game - but not, I believe, in this particular case and occasionally owit others too, where sufficient information can be communicated in photos to show a sufficient range of characteristics and phenomena all present in one specimen to allow an intelligent guess at the gem ID to be a reasonable exercise of deduction.
Anyway, time has passed and I still feel that the effort of putting the photos here is worth it if it interests just one other person sooo... just for you, the photos are all attached herewith...... or would have been until I just discovered the new site limitation of photo file size to 100kb Never mind. If you would like to see the photos, PM me an e-mail address and I'll send them to you directly as attachments to a return mail. When you've looked at them, I'm happy to give more information should you have any questions on any of the photos' content, Guess as soon as you think you have enough information for a reasoned deduction. No limit to the number of guesses
