Great provenance as can be seen from picture 1! Although it's only a little fella it is the largest I have ever owned and I was over the moon that it came from it's finder, Professor Kerr Grant.

As I have mentioned before the history of a meteorite is very important to me and I wish I could ask this one lots of questions :)

Karoonda became a household word in scientific circles because of the meteorite which fell to earth 3.6 km away at 10.53 p.m. on 25th November, 1930. A rare event, and to have been observed was also uncommon. It was observed falling from Eyre Peninsula to mid Victoria - witnesses described it as "turning light into day". Also rare was the type it was - unlike any other found, as although of the 'stony' type, it was mainly iron silicates, eventually being classified a "chondritic asiderite". Because of its type it shattered on impact (shaking the township as it did so!) making a crater 46 cm deep with surrounding ridge a little over one metre across, scattering fragments over a two metre diameter area. The largest piece weighed 7 lbs (3.2 kg) but the total of all fragments collected came to 92 lbs (41.73 kg)
