Joan's Crystal

What should one blip for Black Friday? A dear friend of ours brought over a multi-faceted cut crystal ball today. It normally hangs at a window and produces refraction rainbows . Try as I might, I could not come up with a projected ROYGBIV spectrum as such but the exercise DID produce different colours for different facets, enough, perhaps for it to be of interest.

Thank you Joan. It was very kind of you to lend me this lovely thing to shoot. I hope you like the result.
