I received my Blue Carbuncles today. It took about an hour to remove the paint and foil backing from the rhinestone. It's hard to say how big the original is. Given Jeremy Brett's height (at least 6' 1") and accounting for hand size (my hands are a poor model in this case as they are a bit more 'sausage-like' than the late Mr. Brett's) I'd say the 30mm x 20mm is pretty close. This was also the largest rhinestone I could find in this shape and cut. It photographs beautifully. Lighting is everything I suppose. I have a bunch more of these if anyone wants them. I'll probably post them in the junkyard.
