Although wedding rings are now permitted, all other jewellery must be removed. In Hamilton's case, his nose stud is welded in place and would require surgery to be extracted.
Given the situation, the Mercedes driver was granted a two-race exemption in Miami. When that elapsed, a further grace period was applied from Monaco which has also expired.
Given the racism storm that has surrounded Hamilton this week following the remarks of Nelson Piquet, asked as to where he stood going into the race at Silverstone, he replied: "It's kind of crazy to think that with all that is going on in the world, that is a focus for people.
"And I would say that it is worrying because we've got so much bigger fish to fry. We've really got to start focusing on other, more important areas.
"I will be racing this weekend. I will be working with the FIA. I would say the matter is not particularly, massively important.
"I will work with Mohammed [Ben Sulayem - FIA president] and his team so that we can progress forward."
Hamilton - What penalty could he face?
A driver would likely be reprimanded in the first instance, followed by a fine thereafter, and then the addition of penalty points.
