One key to a fake LRL is detector that picks up paper money or diamonds.

Yes, you're right! You need a small sample chamber (empty glass fuse) and put inside, for example, part of 1 US$ bill in very small cut pieces (but if you prefer destroy a US$ 100 bill, is your problem)
.
In this chamber is a coil (1,000 tuns fine wire) wich "noses" the molecules of bill, similar in the sample. Maybe also can helps a source of HV (1,000 V). There are oscillator, filter at oscillator frequency, multiplier of frequency, amplifier with sensibility control and audio system.
Also you can use a xtal oscillator and put the sample in one face (nude xtal). This is similar to technic used in microbalance detector for molecule of explosives and others.
