Numerous 'golden' specks were noticed on the MS images ever since the digital images became available.
One theory at the time was that these were tiny remnants of gold or gold paint, that may have become
stuck on the MS when it was created, possibly in some scriptorium.
In 2014 I asked a conservator to have a look at some of these through the microscope, and they turned out to be drops of 'gum', the material that was used as a binding agent for inks.
The one shown by JKP above may be a bit large for such a thing, but it could be.
