280.60 ct. meteorite impact glass lechatelierite stone.,super rare and yes one of a kind IMPACT GLASS MINERALOID ! the glass contains an element called Ge Germanium, it formed outside the galaxy 14.5 billion years ago and is 10 billion years older that earth a pre solar formation.

These are the best examples of the meteorite mineraloid lechatelierite in the world, big tubes and branching of extreme size within the glass.. 
 Impact glass Lot of 4 tektite lechatelierite impact glass mineraloids, for sale,  WOW ! one of a kind collectable for impact glass collectors. 

RI 1.50 -  SAME AS MOLDAVITE, one major difference is this glass is pure silica and a trace amount of carbon from impact debrie , trees ,grass or plants. it could be the impactor in the glass . All samples are handled with rubber cloves and a clean when tested !

Impactite (or impact glass) is rock created or modified by the impact of a meteorite   Impactite includes shock-metamorphosed target rocks, melts (suevites) and mixtures of the two, as well as sedimentary rocks with significant impact-derived components (shocked mineral grains, tektites, anomalous geochemical signatures, etc.).

Tested at Cal tech. University. XRF, SEM, ROMAN SCOPE != 99.797 % PURE SILICA LECHAELIERITE IMPACT GLASS...!

  1. Pure silica quartz impact glass, like Libyan desert Impact glass pure silica quartz. The refractometer reading is 1.50 glass. The graph shows pure silica & oxygen. The photo shows lechatelierite branching impact characteristics of impact glass tubes forming at over 1,500 2,000  degrees this is the testing done so far cal tech will be testing the Fluorescents of the glass it was so Fluorescent it blew the Roman scope off the charts had to set it to 1 to read it. It is a possibility it contains a rare earth element maybe carbon gas ? Carbon is seen in these test. it could not be a contamination.  I think it is the Fluorescents and a possible clue to what flew buy or impacted the earth to make the silica glass. the flouresent color is golden yellow to orange. in long wave UV lighting.

When a meteor strikes a planet's surface, the energy release from the impact can melt rock and soil into a liquid. If the liquid cools and hardens quickly into a solid, impact glass forms before the atoms have time to arrange into a crystal lattice. Impact glass is dark brown yellow, almost black, and
partly transparent.

THIS GLASS CONTAINS THOUSANDS OF SMALL GLASS TUBES CALLED, {LECHATELIERITE}.
THIS MINERLOID WAS CREATED BY IMPACT AND IS TEKTITE SHAPE .
INCLUSIONS OF LECHATELIERITE CREATED BY FLASH HEATING ARE PREVELANT, SO MANY INCLUSIONS OF CRYSTOBALLITE AND LECHATELIERITE THAT ARE THE CORE SILICA POLYMORPH WHICH MADE THE GLASS. BUY IT FOR YOUR COLLECTION TODAY.
