Is It a Tektite??? While many tektites appear opaque black in reflected light, all will transmit light along thin edges with strong backlighting. Check the color.Australasian , Ivory Coast, Tibetan, and Bediasite tektites are a molasses-brown with greenish tinges. Moldavites are shades of olive to emerald green, and can be quite transparent. Georgiaites are golden amber with olive green tinges. Libyan Desert Glass is straw yellow. ... The transmitted light color is never gray. (Lilac-violet remains an issue, but is probably negative).
Iíve been contacted by more than 1200 persons who were ďamateursĒ in that they were not experienced meteorite hunters and had one or more rocks that they thought might be a meteorite.To the best of my knowledge, only four of those people had found a real meteorite.
Apparently, generally speaking, the odds are not good ...
Haematite seems to be the most common "Meteorwrong" but would be revealed by streak test.
