holdinghistory Posted October 9, 2019 Share Posted October 9, 2019 I just got this neat piece of Burmese amber in the mail. Rough piece with a sea lily star in the attached rock. It is a very large piece (66 grams), and looks neat rough as is. But I can't help wondering what it would look like with the amber portion polished, especially if there are any insects inside. Any thoughts on whether to polish it or leave it as is? Link to comment Share on other sites More sharing options...
Darktooth Posted October 9, 2019 Share Posted October 9, 2019 Maybe polish a "window" on a portion of it to see what may be inside. There was an Amber expert who gave a talk to my local club. This is what he would do to determine whether or not a piece was worth the time to polish or not. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Wrangellian Posted October 9, 2019 Share Posted October 9, 2019 Tough call. Ideally you would have someone with enough experience with this material to know what the chances of there being an insect in there, and how the stuff behaves when you try to polish a window on it as Darktooth says (ie. not going to crumble). I guess it's worth a try if you think you can do so without affecting the crinoid ossicle. Link to comment Share on other sites More sharing options...
holdinghistory Posted October 9, 2019 Author Share Posted October 9, 2019 Usually polishing a window is the way to go, but this one has so many different angles that the window option will only show a small part. The rock on the one side and a few other factors means I can't backlight it with a flashlight to try and see inside. So it is going to be a complete mystery!

caldigger Posted October 10, 2019 Share Posted October 10, 2019 Nathan, so if you can't get it backlit, will you really be able to see what it offers inside if you do go ahead and polish It? Pretty much every piece of amber we see kind of depends on that back lighting to view the inclusions. Link to comment Share on other sites More sharing options...
holdinghistory Posted October 10, 2019 Author Share Posted October 10, 2019 Part of the reason I can't get it backlit is because it seems to have some stress cracks (probably from excavation), and the amber is a little dark in areas, so I can't light it from the side. If I polish it, I think it will be more clear (hopefully), and I could also potentially remove some host rock that doesn't have fossil material in it, allowing for more back lighting. Even if there is nothing in it, wondering if it would look better rough or polished? I can see it being neat either way. Link to comment Share on other sites More sharing options...
Ptychodus04 Posted October 10, 2019 Share Posted October 10, 2019 I personally think that amber is one of the few materials that is more attractive polished than raw (personal opinion) so I’m in the polish camp regardless of inclusions.

daves64 Posted October 10, 2019 Share Posted October 10, 2019 The 2nd & 3rd pics show what looks to be a lot of heavy fracturing. I deal with that a lot hand polishing Indonesian amber. Chances are, if you try to remove some of the outer rock, it could come apart. Although, I've had some that had more fracturing than that looks to have & still have the piece stay intact with filing, sanding & polishing. With the fractures, you just can't tell what it will do. Carefully polishing some of the angles by hand might be the best route. It would open a few small windows & allow you to get some light inside. Fortunately, amber is soft enough that wet/dry sandpaper works well on it by hand, but keep wetting it to rinse it & keep it cool. I usually sand to a 14k equivalent grit, then buff with a sheep skin chamois. I haven't actually used polish on any I've done yet. I'm with @Ptychodus04 on polished amber being more attractive, even though I've had a few pieces that were fantastic raw.

holdinghistory Posted October 11, 2019 Author Share Posted October 11, 2019 I decided to start polishing it. It actually appears to be quite stable so far, I think it will come out nice insects or no. 1 Link to comment Share on other sites More sharing options...
Mousehead Posted October 18, 2019 Share Posted October 18, 2019 Would love some updates on this. How well did it polish, and what did you find inside? Link to comment Share on other sites More sharing options...
holdinghistory Posted October 19, 2019 Author Share Posted October 19, 2019 Just finished it up last night. I am very happy with how it came out. No insects that I could see, but it took the polish well. I decided to not go completely smooth with it in every spot to leave some of the natural characteristics it had. Other parts I smoothed out. Also made a flat base so that it can stand on its own as a display. Removed some of the rock in spots, but left a good part of it on. 1 Link to comment Share on other sites More sharing options...
daves64 Posted October 19, 2019 Share Posted October 19, 2019 Looks pretty good! And the fracturing looks like what I deal with a lot with the Indonesian amber. With the amount of fracturing, you probably wouldn't be able to see any bugs or debris clearly anyway. I like it.

peystone Posted October 20, 2019 Share Posted October 20, 2019 I love the patchwork quilt appearance of the amber, goes to show that crystal clear is not the only amber of beauty. Link to comment Share on other sites More sharing options...
