Brazil has a rhombus on their national flag. The American states of Arkansas and Delaware each also have a rhombus, as well as a historical flag used for a Napoleonic campaign in Italy. The Empire of Brazil, Portugal, and the Algarves used a flag with a rhombus as well, and is the basis for the current Brazilian flag.
