so who's a lucky girl then

In fact it was on the tip of my tongue to say that the butter butterfly did look rather like the Sowerby trinket tray insect.
Much to my shame have to admit to collecting larvae of said insect (from fennel on the Norfolk marshes) many years back, and breeding out the adult - tis indeed a spectacular and colourful butterfly - although as with many glass representations there is much stylization.
Regret I don't frequent either Twitter or Facebook, but can imagine how gorgeous a uranium example must look.
Again, my congratulations, and I will keep an eye out for another, and if it glows or shows iridescence will let you know.
