There are multiple problems with your measurement attempt.
1. Use of a basically "shielded" RCA cable, with a tiny amount of "unshielded" center pin at the end, does not a good probe make. Used open circuit (as it appears to be), it MIGHT be capable of picking up gross and overwhelming amounts of E-field, but would also be prone to small amounts of B-field induction, making it a poor probe to check for the presence of E-field shielding.
2. The overall wiring shown in the photo's looks quite chaotic and not cleanly laid out or routed for best results, it is entirely possible that even if the stones had a shielding effect, the excess wiring all over would have allowed the detected spectrum to be picked up anyway.
3. The spectrum analyzer used is basically good for only the audio band. Period.
This is not going to allow pick-up of RF frequency emissions, which is one of the spectrum bands in question.
4. Your spectrum of picked up radiation does NOT look like a prodigious amount of radiation from a switching power supply, in fact, it looks suspiciously clean and missing all kinds of power line harmonics and other switching supply artifacts.
Having measured and dealt with noise and radiation from a variety of switching power supplies, your spectrum analysis results look much more like simple AC power line fundamental and a small handful of weak harmonics, or about what you might pick up from simply being near a line cord, or a simple linear power supply.
Thus, I suspect you are NOT measuring what you think that you are.
5. Your source of crystals is not exactly a golden repository of lab certified gems. They might not even be what they are labeled, or they might be of such a poor grade as to be equivalent to simple gravel in terms of the effects being sought.
It is hard to say what else may have been done poorly in terms of set-up, wiring, measurement, or materials quality, but this is way far off from any sort of definitive or even useful measurement.
Net result: more confusion than confirmation.
