Attached, you will find some nice tools that might help some of you.
The KML has many jewel hunting spots in it. It's sorted and the placemarks are set beside of the jewel location. You might add other cities and send them to me for updates.
In the ZIP file is a Firefox Search Extension for searching the download repository as quikly as possible. See Firefox documentation for help...
Finally, I made a bookmarklet for entering all values on the convertion page. Maybe you like it as much as I do
It works very simple. If you have some jewels then select the text from "Jewels" untill "Diamonds to convert" and run it. If you have no jewels at the moment just select the text from "Oil" untill "Diamonds to convert" and run the one titled "without Jewels". After filling all input fields with its values there comes an alert window "done". You could remove that one, but then the page always displays the amount of jewels and you need to press the back button...
