Two necklaces are available from contests in Greece. The usual two web proxies we use for Greece are down. Unless you know a working web proxy these are only available through a MANUAL proxy. The only one I found that was decent is: 195.200.193.156 port 8085
(if it is slow for you use my trick: wait for the page to start to load (turn white), turn off the proxy, highlight the URL and tap your 'enter' key)
Both contest URLs are below the necklaces you get for them. You know to change 'view' to 'finish'. You can get both necklaces while in the proxy. The gold one will be in your Beauty Parlor. The lei will be in a box in your suite. I hope I've made this easy enough to understand.
