These days gold is hovering around $1,000/oz (using the bastard troy ounce and not the much more useful and common avoirdupois ounce) and platinum is somewhat higher. Kitco has a nice set of precious metal charts with both current and historic prices (www.kitco.com/charts/). Interestingly palladium is a jewelry metal that has some working properties that are similar to platinum, and this last year the palladium market took a shit, dropping to below $200/oz for a bit.
So when I ordered the metal for my lady, I got some Pd for me, to use when there was a lull in projects. As it happened the other night one popped up, and I had the bar of Pd with me at the time. I did a couple of simple operations to turn my little grey rod of 95.0% Pd into a flat bar to make into a ring shank.
I rolled it down a few more times, and then annealed it to ease the bending processes to come, and, wouldn't you know it, that little fucker blistered on me.
I'm a little pissed, since the thing is essentially ruined, but I've never worked with this metal before so I don't know if I fucked up or it was a bad ingot to begin with. Hopefully the company I got it from will help me out.
