We didn't expect anyone to send us free gold and platinum, but this is pretty close! This small sample was kindly donated by George (not 007) Lazenby, who saw the slashdot discussion. It came in a lovely little plastic vial.
George got this and the other samples he donated at a surplus auction of his high school. It seems he was the only one there who appreciated the erbium foil. This sample and the others he sent had been donated to the school by a former student who worked at NIST (National Institute for Standards and Testing), where they had been used as x-ray calibration standards. This means they are probably very pure.
