Remember the tuple (g+, T+, p+) that was used as a nucleus cyclic set to build up a nucleus by stripping the associated atom of its negative charges and allow the weak fields from the orbiting positive charges to attract g+ particles, the first member of the next layer making up a nucleus?
Well, because gem stones are relatively stable in temperature, it is unlikely that the bonds holding their crystalline structure involve T− particles. If T− particles forms bonds, such bonds will interact with T+ and T− particles just as chemical bonds are formed and broken with a supply of positive and negative charges during electrolysis.
It is more likely that, for example Amethyst, the molecule SiO2 is stripped of its outer electrons and the bare paired proton orbits generate weak gravitational fields that attract a layer of g+ particles. The stripped SiO2 molecules with a valid Quantum Number forms a quasi-nucleus, over which g+ particles are in orbits balanced by g− particles. It is the bonding of g+ and g− particles (the equivalent of covalent bonds when p+ shares e− particles), that buildup the crystal.
Since, both g+ and g− particles are involved, gem stones are rare unless environmental conditions provides for these types of particles. Since, g+ pulls you up and g− sets you down, earthquakes zones have an abundance of both these particles. From the post dated 12 May 2016, "Seven Up!", where negative charges are removed from Cu to form a crystal lattice, in a similar way, an abundance of both g+ and g− particles initially buildups a quasi-nucleus around a stripped SiO2 and then a depletion in g− particles is needed to form crystals.
But wait, maybe a diagram to show how SiO2 forms a nucleus is in order. It is just like CO2 with C replaced by Si. Why not then a CO2 gem? It could be that C is too small to accommodate the two Os into its fold to form a quasi-nucleus. Si being bigger, both Os can approach closer where the particles orbits overlaps and form a distorted spherical entity that acts like a nucleus over which a g+ layer forms.
The presence of the g+ layer will add mass to the crystal. When a crystal disintegrate with the release of gravity particles and the addition of e− particles, its mass should also change. We may isolate gravity particles and find their masses from crushing crystals with a dash of electrons.
Good night.
