Although Henry VIII married six times, only two of his wives, Katherine of Aragon and Anne Boleyn, were actually crowned Queen consort. Constitutionally it makes no difference if a Queen consort isn't crowned. However in medieval times it was a sign the King trusted his wife and thus the Lords and country knew he had given her the authority to act in his absence; for example if he was away at war. As a footnote if Jane Seymour hadn't died after giving birth to Henry's only legitimate son Edward, it's more than likely she would have gone through the crowning ceremony as well.
