Darwin Glass, Tasmania

The impact event that produced australasian tektites raises more questions than I would dare to begin to list. But the geographic distribution patterns and variations in chemistry have always made it hard to think in terms of one individual impact. Darwin glass offers an important clue. Clearly, neither Darwin glass nor its mother crater are genetically linked with Australasian tektites but they do appear to be of identical age! Think of the string of fragments involved in the collision of comet Shoemaker-Levy 9 with Jupiter in 1994. I currently think there's a case for at least three impactors in the Australasian event (Tibetanites, Indochinites-Philippinites- Australites, and Darwin Glass).

I've been told that most of the area where Darwin Glass was previously collected has been incorporated into park lands and collecting is no longer permitted. Buy enough for future generations, as the supply is dwindling----

Here is some of the finest Darwin glass you will ever see anywhere. These were the 50 or so best specimens in something like 10 kilos that we sorted through. Enjoy! There's also some more typical material at lower cost shown in the final image.

"Sold" material updated 9 February 2012
Total monsters as Darwin Glass goes. Specimens up to 22 grams, and mostly with distinctive morphology.
VERY SWEET little twisted ropy curls---even a little teardrop! Fine stuff.
More convolutely ornamented and irregularly shaped specimens, all with remarkable preserved external skin features.
As above. Good material!
Mostly drops resembling blobs of melted tar or candlewax!
Some very rare and VERY special super-pale specimens. These are mostly paler than Libyan Desert Glass. The specimens on either end are more typical coloration to permit comparison. These pieces were all that there was of this variety in around 10 kilos of material! RARE.
Darwin glass as you usually see it. I was once very pround of this inventory because nice chunks of Darwin of any description are relatively hard to find. While the stones in this lot don't compare to the specimens in the preceeding photos, it is still good Darwin glass, and much more economically priced.
