Arthur, no reason to feel sorry for suggesting a possible connection. I'd never noticed the Duchess of Cornwall's brooch before, and as Millie wrote in her post below, a gift is not an unlikely idea.
The similarities are indeed striking. In the photos you've provided the shape of the DoC's brooch comes across really well. I'm usually not a fan of these insect brooches, but here the rather stylized straight form of the antennas mirrors the straight gap between the two pairs of wings which adds a certain tension, a sort of sharpness to the design which I find very appealing. Adding to this effect is the slight curve at the bottom of the larger wings which "opens" the gap between the wings and makes for a good contrast. That's why I noticed that exactly this "sharpness" is missing in the design of the DoD's brooch.
