I think I’ve gotta go with #Dioptase!

It’s blue-green (so leaning towards the blue vote), a copper mineral (yay) & it’s PYROelectric!!

Vote Dioptase!!!

Axinite:
- A mineral group containing four species (Fe, Mg and Mn rich axinite, and tinzenite)
- Produces an electrical current when heated/cooled rapidly (pyroelectric) and when stressed (piezoelectric)
- Its name comes from the Greek word "axina" (axe) #minerals
Cluster of deep reddish-brown, slightly flattened prismatic axinite crystals on a white albite matrix. From Baja California, Mexico. Specimen on display in the Natural History Museum, London.

Analcime:
- A silicate mineral
- Also known as analcite
- Forms in basalt
- Its name comes from the Greek word "ανάλκιμος/analkimos" (weak), because it develops a weak electrostatic charge when heated (pyroelectric) or rubbed (piezoelectric) #minerals
Large white crystals of analcime. From Bowling, West Dunbartonshire, Scotland, UK. Specimen on display in the Natural History Museum, London.

A professional looking picture where the green-blue dioptase crystal rising out of the beige brown rock underneath it shines with inner light. It looks almost haunted. The background is an indistinct reddish orange-brown and black for contrast. The top of the crystal is bright icy blue turquoise and below it there is as if a green light shining from inside the dioptase. Stunning colours or beauty. Saved with the name below, suggesting it's maybe by someone called farhanfarhan. farhanfarhan_Dioptase_crystal_taken_with_Nikon_DSLR._20mm_lens.png Another special class of crystals are pyroelectric crystals. They are characterized by the existing pyroelectric effect: If a pyroelectric crystal is heated, a measurable voltage generates on its surface. From this voltage, one can deduce the temperature change of the crystal. Thus, a pyroelectric sensor is a temperature sensor. There is a profound relationship between pyro and piezo sensors: Every pyroelectric crystal is also a piezoelectric crystal (but not vice versa). To understand this, let us again look at the arrangement of the individual atoms: Figure a.) shows the piezoelectric hexagonal crystal from the previous chapter. Let us now imagine that this crystal is slightly longer in one direction than in the other – figure b.). As you can see, this piezoelectric crystal is now asymmetric around the center and no longer electrically neutral. One can deform this new crystal with an external force, which still leads to the piezoelectric behavior explained before. However, we do not necessarily have to apply an external force to deform the crystal. Another possibility is to simply HEAT the crystal, causing it to expand. This expansion increases the asymmetry of the crystal, because the atoms (as seen in figure b.)) lie asymmetrically around the center. If the atoms were symmetrical around the center (figure a.)), the thermal expansion would be the same in all directions and there would be no asymmetry. In summary, this means: Heating a pyroelectric crystal leads to an expansion of the crystal lattice. Due to the piezoelectric effect, this expansion of the lattice now leads to a measurable electrical voltage. The piezoelectricity part is explained first on the site, but as the focus here is pyro being better or more expansive, that came first. Here is the piezoelectricity explanation from the site. In short, expansion, asymmetry, zap. Expansion through heating makes things even easier, but only pyroelectric things are ALL also piezo ones. "Figure a.) shows the atomic arrangement of an “ordinary” non-piezoelectric crystal. The red dots represent positively charged atoms, the blue dots negatively charged atoms. Such an atomic structure appears electrically neutral to the outside because the negative and positive charges are symmetrical around the center (the red-blue star) and therefore cancel each other out. Even if this quadratic atomic structure is compressed by a force, the atoms still lie symmetrically around the center and the configuration appears electrically neutral to the outside. The situation is different with piezoelectric crystals. The atoms of many piezoelectric crystals also lie symmetrically around the center when no force acts on them. Figure b.) shows such a piezoelectric crystal. However, if a force acts on this atomic structure, the shape changes drastically. You can see that the atoms are now no longer symmetrical around the center. The positive and negative charges can no longer cancel each other out and a charge imbalance occurs. This imbalance manifests itself in an electrical voltage."

I voted #dioptase because it
is pyroelectric and because its color is teal.
#Wavellite did not move me.

Some rocks & metals neutralize energy like radiation such as jasper others give off radiation like uranium.
Some rocks & crystals deflect energy like mica & some absorb & amplify energy like calcite.
Quartz is a pyroelectric amplifier.
Hematite is magnetic.
Science has proven energy frequency heals.

Remembered there was a company making neat little pyroelectric x-ray generators for XRF, went to look for it and found it was discontinued, but they now make a source using a laser heated cathode for smaller spot size and higher reliability.
