The Queen has a known affinity for brooches and has received untold numbers of the jewelry item as gifts from heads of state the world over.
Since the theory went viral, other jewel watches have come forward to say that the Queen was showing her disapproval through more than just her brooches.
Aside from the aforementioned faux pas, reportedly Donald Trump also had Her Majesty waiting which is arguably even worse considering the rule is to always arrive before the Queen at a meeting place!
The Obamas gave her the 1950 vintage brooch is in the shape of a green flower.
Hand selected by the Obamas from CT jeweler Tiny Jewel Box's vintage assortment, the brooch was crafted in 1950 from 14-karat yellow gold, diamonds and moss agate.
Contrary to Trump's statement, however, the queen has reviewed her honor guard many times over the last 70 years.
"I find this an incredible stretch to think that the Queen is trolling Donald Trump when her sole goal is to show him the ultimate royal hospitality", she told CTVNews.ca. Is the Queen sneakily signaling her disapproval of America's current president? And since the Queen is notoriously fastidious about protocols of state, it was hardly an accident that she wore the "American State Visit brooch" as Trump set foot on British soil.
The Queen inherited the brooch in 2002.
It has been pointed out that the brooch - a palm leaf design - is closely associated with public grief, because of the famous photograph that features it, called "Three Queens in Mourning".
The Sapphire Jubilee Snowflake Brooch was a gift from the Canadian people.
