what would be the most interesting metal to make a ring from?

I suppose if you were getting married... one of the most interesting metals would be a magnetic alloy

an interesting metal for a ring...

you probably couldn't use iron, because that might rust

well, platinum and gold are often used... so is copper, so

it can't be any of those. I think it would have to be...

diamonds are a girl's best friend, just shove some diamonds in there.

you know what I would like? I would like to have some kind of--

I know, like a... a ring that encases mercury.

I suppose quite a novel ring would be made of mercury

so it's like something like a strong glass or something like that you know

but obviously it's got to be delicate to fit on your finger but say that the

mercury will just constantly slosh around

we really have to cool it down to keep it on your finger

that would make the most interesting thing and also the you know it is quite

risky wearing it, isnt it? 'Cause any time if it breaks so you just could

cover yourself in mercury--maybe not the best idea.

I don't know

interesting metal...

interesting...

goodness... i dunno, titanium is pretty light, very stiff

what about a cesium ring? [laughs]

platinum would be quite nice... but gold is also nice, i mean--

interesting? no, i don't know maybe they're just standard. what be most interesting...

so the melting point of gallium is quite close to the body temperature, isn't it, so

if you could make a ring out of gallium whatever your normal body temperature

that the ring would probably sit quite nicely on your finger, because it's

cooled by the environment, but if you would get like, hot and perhaps feverish,

and the ring would probably start to melt, so that would be quite interesting

[laughs]

I don't know!

yeah, I don't know.

I'd like to see just how heavy a lead ring would be

imagine if a couple had magnetic rings, then when they [claps] held hands, they'd stick together

oh, I think bismuth would be good, cus I remember the bismuth videos, and it looks very pretty.

[laughs]

I don't know

wedding rings a really special, aren't they? you know, it's what matters to you and

it's the metal that you associate with the person you want to be with.

carbon fiber-- that's not metal is it though? titanium.

I don't know... be expensive. I think, just go with gold. it's-- it's pretty good

Mark, my ring--my wedding ring is made out of-- it's made out of Welsh gold

so, obviously because of the Welsh connection, so my wife and I have got a

matching Welsh gold wedding ring, so.

BRADY: Well, how is Welsh gold different to other gold?

well, Welsh gold's no different to gold that's made anywhere else, you know

perhaps Ethiopia or mined in South Africa, but i suppose what makes it Welsh gold

is where it was mined, and it was mined in a-- in a small valley in north

wales so it's quite close to my home and quite close to my family links
