Hi,

Did you receive your unit yet?

I bought mine two weeks ago from Kassoy and it came with scratches on the bottom filter (see picture below).

Plus, the bottom plate doesn't completely open (see pictures below).

I returned my unit to Kassoy and they will send me a replacement unit.

I haven't received mine yet. Most likely Tuesday. I'll let you know. I was so excited for a piece of equipment like this. It's really prefect for my needs. I hope the damage on yours was a fluke...

Hi Jim,

Did you receive your Gem-A folding polariscope yet?

I did. But I've been at a trade show so I forgot to update.
It didn't have scratches but it doesn't open all the way, like yours.
It's really no more than I expected, really. I can't imagine that your replacement will open all the way either. It's the folding loupe model that Gem A chose that's the problem. They're going to send you one without a scratch. I think that's the best you can hope for.
Sorry to sound so negative.
It is, however, better than the one I made at home! :)

You're absolutely right, the problem is indeed the loupe model Gem-A chose. It's like they chose the cheapest one available out there.

There are some models that look way better on eBay :

http://www.ebay.com/itm/10x-Folding-Lin ... 3a81abcf83

http://www.ebay.com/itm/New-Portable-Fo ... 3a729268d8

Note: Maybe many years ago Gem-A made a large production batch with that specific loupe model that was easily available at that time and they're still selling units from that production batch.

I'm a little confused.
Are we talking about a polariscope or a magnifying device?

Hi Barbara. We're talking about a travel polariscope, but those ebay links were for linen loupes just to illustrate that there are better loupes out there to use as a base for the end product. (Which would be a polariscope).
I used my new gemA polariscope during Vegas this past week and it was exactly what it should have been. I didn't buy the light source to accompany it because there are SO many appropriate light sources around.

the gem-a foldable polariscope is very small when folded, and still big enough when unfolded so to allow use of a conoscope on top of your stone. Nice to see that they finally decided to make a light source that actually fits it (the previous light source had a curved surface which was making it very impratical)

Otherwise, someone in the forum had suggested combined use of polaroid sunglasses and a flashlight which glass top has been replaced by a piece of polaroid filter.

One can purchase one for $34

And I'm sure, if you are clever, you could build something similar with a pair of polarized sunglasses and a flashlight torch.

DavinciQc, this linen tester is to small to be used as a travel polariscope but its a very good magnifying device, this is the 10X DELUX linen tester =D> its made in india and its one of my favorite magnifiers, for a travel polariscope look for some thing larger.

If you really feel like you want to make your own, see my earlier thread where I, sort of, documented the process.
In the end, I bought one!! But maybe a smarter, more resourceful person could have done better. :)
