I haven't used this guys equipment, but if his feedback says anything it says he has a good product. 99.9% positive feedback and over 11,000 customers. That is pretty damn impressive.

Well, my desire for a new toy got the best of me, and I order the microsope. I didn't order the one in the link I posted, but the next model up that the same supplier offers, along with a digital camera for it. It turns out it would cost me more to mount my camera on the scope, than to just buy a dedicated camera. Hopefully it will arive on Monday or Tuesday, and I can offer some feedback and maybe some images.
The microscope, with the 1.3mpixel camera and shipping was about $750.

Me too... I've been trying to convince myself that I don't really need a microscope... but I fear it's a losing battle. :) I'd love to know if there are "budget" scopes that are worth getting.

And then....

I guess if I got a new microscope I might be offline for a while as well. I've been looking at those scopes for a while, and I too really want to hear what you think.

Really?
If I got a new scope, I'd be online constantly with a blow by blow. :P

Ok, here is the update on the microscope.
It arrived well packed on Thursday. I had but a few minutes to open the box, have a look at it, put one stone under it, then I had to scram. My wife had the car all packed for a long weekend trip to NC to view the fall leaves in the mountains.

Back home late tonight (tuesday). I can say that so far I am very impressed with the microscope. The opics are bright and very clear and sharp. The lights work well as does the dark field. It came with extra bulbs, a cover, and number of differnt background glasses. I have yet to hook up the camera, but thats next. The total price with shipping and the camera was about $760. So far, it looks like a great buy. I'll post some pictures once I get it hooked up.

Just to be clear, I ended buying this microscope, not the first one I posted.


http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170040733706&ssPageName=MERC_VIC_RSCC_Pr4_PcY_BIN_Stores_IT&refitem=170033084287&itemcount=4&refwidgetloc=closed_view_item&usedrule1=StoreCatToStoreCat&refwidgettype=cross_promot_widget

I got the camera hooked up to the pc last night. I'm not that impressed with the camera, and may return it. I bought it, since it was less expensive than the adapter to attach my Nikon D70. I think now that I'll go get the adaptor for the Nikon and try that. ONe plus to using the Nikon is that I will not need to have the camera near my PC.

Im no expert on gem micoroscopes, and have nothing to compare this to, but I am critical when it comes to optics, and must say this micorscope has me very pleased. I couldn't picture how much better a $4000 GIA scope could be. I think I would rather spend the left over $3500 on some gem rough. To me, this scope's images are razor sharp, bright, and the whole scope has a quality feel to it.

Now, here is my question. How the heck to you get your stones clean to view them? With the naked eye, they look perfectly clean, but even at low power I see fingerprints, dust, and all kinds of junk on the surface of the stone. I use a microfiber cloth to wipe them off, but it doesn't seem to get the stone clean enough.

Try alchohol....isopropyl.
Works well for diamonds.

You can get 70% strength at most drugstores, but you can also get 99% at some drugstores or electronics stores (it's used for circuit boards and component work), it's usually about the same price. I don't know if one is better than the other for the purposes of cleaning a gem, but I usually end up buying the "stronger" stuff... I guess it just seems like a better "value". :)

Most alcohols have added substances that may create a film, this was done to get rid of the spiritus addiction. Ask your pharmasist for the almost pure variety and tell them what you need it for.

My understanding is that isopropyl alcohol ITSELF is poison...

Maybe you're thinking of denatured alcohol?
