An easier way to find item IDs:
1) Search for the item on mqemulator.net. Eg, for blue diamond see this page:
http://mqemulator.net/item.php?id=22503
2) Note the ID. You can see the ID in the URL and also in parentheses on that page. In this case, the ID is 22503.
3) Convert the ID to hexadecimal. You can use a site like
http://www.binaryhexconverter.com/de...-hex-converter to do this. In this case, the hexadecimal number is 57E7.
4) The number should have two 0s before it and should be padded with 0s at the end so that it's 45 characters total. In this case, the number would be 0057E7000000000000000000000000000000000000000.
5) Format things as Sorn described above (eg, with the control character).
