I am looking for info &/or prospective buyer(s) on some stones I believe are white/colorless natural spinel,xxxxx same on topaz,xxxxx same on some aquamarines (or almost). Unless my gem tester (Kassoy- thermal conductivity)is wrong (I have tested it against stones of known origin,xxxxx even glass), they *are* colorless "all the above.!" How much of it is *gem quality*, I'm not qualified to speculate on, but what reasearch I've 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),xxxxx where the normal parameters of crystal formation have been altered by other natural forces. The only trait *I* havealtered is the reflectivity of how light enters or leaves by *tumble polishing* them with a variety of commercial grade grits, xxxxx They could be classified as natural *Gemstones* just as they are,xxxxxnow. Some show traits of other crystalline formation (tetrahedrals,xxxxxetc. [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. That's 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,xxxxx
