I personally don't think any of them are pretty "rare". I presume that one of your family members travelled overseas and hence they are lying...
I think there is a confusion that is going on right now. While MOST cleaning will ruin the values, you have to understand that it is the...
1 1 2 3 4 8 13 Fibonnacci 3.1415926 pi 1.6180339 phi function. Is this some kind of test? :desk:
That's because quartz is madely made out of silicia or silicion dioxide, which is rarely active with other metals. The rust "dust" that covers the...
I just don't see how it should work. I mean, from the basic chemistry, rust is just FeO or FeOH. Once the rust has "eaten" away parts of...
I see plenty of problems with the new technology. Wait till you get some mafia men getting hold of those machines and all you know next is that...

The ones that I see are often 4-5 digit figures. That of course is because they most certainly are stunning pieces, "certified" by dealers, and of...
