This is the story of a private art installation in a terrace in NYC:
"Designer Lisa Perry and her hedge-fund hubbie Richard live in the luxury apartment, and prior to her 50th birthday she "had only to look out the window for a clue to what [he] had in mind as a gift. [He] gave his wife a ring that is a miniature version of Jeff Koons’s green Diamond, which graces the terrace of their New York penthouse."
The first image is Jeff Koons Blue Diamond.The second and third are images of this private installation.
In the capital of excess it seems extravagance will never go out of style.
