Fakebusters: Vivid Moonstone

This is an odd Fakebusters, as this is not something artificial claiming to be a stone, but something heavily modified. This is a vividly dyed piece of rainbow, for ummmm... aesthetic purposes? I find that rainbow moonstone is utterly stunning with its iridescent sheen, however this is downright gaudy. Unfortunately the feldspar crystals take colour reasonably readily, so this painfully ugly crystal is born.
