Here's a large, ?1980's gilt pendant with a blue (aqua) glass stone in the middle. It is decorated round the edge with wire work. I have put it on an Adrian Mann chain but the loop is big enough to take a thicker chain. Full details of the measurements are on my web site - www.gillianhorsup.com and the reference number is 2393 B108/37 - price £88. Love this because it makes a statement! I have other gold tone jewellery in the shop if you can get to Grays Antiques in central London.
