My sweet Max, you could wear it on a (breakaway) chain 'round your neck, Dearest. Just a thought.

Titanium is all the rage with jewellers for a number of reasons - and, for jewellery grade stuff, IS quite expensive. I apologise however for not knowing the relativities of price with other metals. Fancy a visit to the London Metal Exchange site anybody.....?
One of its benefits is that it passes through a range of vivid colours when heated (as do other metals, but arguably not so prettily). The colour is retained when it cools, so the item can be blue, straw, pinkish, violet or some other combination. If the heat treating is applied locally on the piece it can exhibit a range of colours across its face.
My neighbour's son, a talented young jeweller, made a beautiful ring from gold and electric blue titanium. It was like a sandwich, the outer band of gold had a celtic pattern cut into it, exposing the blue titanium below. An absolute eye catcher.

Ooo, I didn't know they could make colored titanium. I wonder if that'll be the next colorful Mac thing: Blue Titanium G4 Powerbooks. (No, probably not, all there products are white now.)
I've actually been wondering if my Titanium Powerbook is actually titanium. It's a dull gray, not really shiny at all, and there are a few scratches on the bottom. I had the impression that titanium was impervious to just about everything.

Dear Jazzo: Titanium can be made fairly hard. I have a set of drill bits that package said were titanium, but I am sure they are just plated or something. For aircraft, the wonderful thing about titanium is that when air friction at high speed heats it up a lot, it does not sag the way aluminum would. One undesirable thing about it for boats is that it is a bit brittle when very cold. I wonder if it will ever be used as girders in big buildings for that reason. I thought at one time magnesium would have very desirable uses in buildings, until I remembered seeing German WWII aircraft made of magnesium burn like gigantic Forth of July displays.

Magnesium simply shouldn't be used where intense heat is likely to occur. Therefore, no buildings, no warships and no military aircraft should have it in their structures. The Brits were nuts to use it in their warships, but even they learn. Titanium, as stales said, goes through a range of colours when it's heated, and this colourisation can be controlled quite minutely by the application of heat at the point when the colour is desired. Me missus has a real liking for expensive titanium earrings which are made in a range of colours by just that process. Whoever invented the method should be taken out and shot ...

noun-verb number agreement Calme-toi, Chéri--we love you anyway. Plus, that sort of thing is easy to do when one is caught up in the "heat" of the moment...

Dear Jackie: " underable " should have read " undesirable".
