I am looking for info &/or prospective buyer(s) on some stones I believe are white/colorless natural spinel,xx same on topaz,xx same on some aquamarines (or almost). Unless my gem tester (Kassoy- thermal conductivity) is wrong (I have tested it against stones of known origin,xx even glass), they are colorless all the above.! How much of it is gem quality, Im not qualified to speculate on, but what reasearch Ive done on the web suggests it is rare to does not exist naturally and could be quite valuable. I found it by testing out a crystal theory of mine (which proved itself to be just as I suspected),xx where the normal parameters of crystal formation have been altered by other natural forces. The only trait I have altered is the reflectivity of how light enters or leaves by tumble polishing them with a variety of commercial grade grits, xx They could be classified as natural Gemstones just as they are,xxnow. Some show traits of other crystalline formation (tetrahedrals,xxetc. [cubic]) which were unseen till several million years host material was broken/ground off (by me) though the previous year and did not fit the right habits for the material I suspected them of being. Thats when I purchased my thermal tester.I am at a point where my limited testing resources have come to an end. My reasearch indicates that the thermal properties of a given material cannot be altered except through massive amounts of heat or radiation as with metamorphic rock/minerals. I can assure you these stones have not been heated or altered. I may have mistakenly called some spinels topaz and vice versa because the thermal scales for each actually overlap to some degree. I found that the hardness scales were also relative to heat transfer speed and/or specific gravity/density ie., diamond, corundum/sapphire, ruby, topaz, spinel, jadeite,xx
