Loco London is a 400-ounce pure gold brick with a purity of 99.5%, which is kept in the underground vault of London.

London gold meets at least three conditions:

1. Shops in London. The same gold bricks, stored in Zurich, become Zurich Gold, and stored in new york, become New York Gold. And the price of the same BRICS in London is different from that in other places. Why? There is freight. The most active spot gold in the international market is London gold.

Second, the purity is not less than 99.5%. The gold purity of Shanghai Gold Exchange is 99.99% and 99.95%, which is higher than that of London gold.

Third, it weighs 400 ounces. Only 400 ounces (12.5 kg) of gold bricks are good delivery gold bricks. 1 kg BRIC is not a qualified delivery variety.
