Years ago you used to be able to buy fab second hand rings for not too much money on ebay...now you can buy new crappy rings on ebay for quite a bit of money so I don't bother. People have got wise to the idea that they will make more by selling old rings at a traditional auction rather than online sadly. This is one of my fave rings I bought years ago. One of my to dos is to get it valued...just never get round to doing that sadly...but it is on the list. Its an amethyst coloured thing but it changes colour from vibant red in artificial light or candle light to a verylight blue/tinges of grey when I hold it up to natural light in the sky- bizzare but lovely.
