I have tons of jewellery and stones, I have magpie like tendencies towards anything sparkly, colourful or shiny and as far as I am concerned I can never have enough
I am always skint though, so I don't have anything really expensive. I don't think I have ever spent more than about £20 on a single item, perhaps my fluorite sphere which was £21.50, but it is a fair size... about 5 inches in diameter maybe, and a good couple of kilos in weight. That was the trade price though, cos I was buying for our stall at the same time, I would never have paid the retail price for it, lol
Some of the rocks and stuff I have lying around I have found when out and about, and some I have bought - but I never pay much for them.
As for jewellery, I buy myself the cheapo tat that costs a couple of quid but it isn't the end of the world if I lose it. I have made a fair bit of stuff out of silver myself, I didn't keep any of my gold work but I do have a platinum and sapphire pendant I made - never got around to having it hallmarked though, couldn't afford the fee after I bought the materials, lol
I do have some nice jewellery, but that is mostly pressies. My mum worked in a good jewellers for years so I have a lot of stuff from there. I think my favourites would be my tanzanite and gold ring which was a 21st present, and the garnet and diamond ring I got a couple of xmases ago.
