I stumbled upon this conversation while trying to find out the value of this "Risky Business" egg on the internet. I was the crystal buyer at Bloomingdale's for four years in the 1980's and the company GAVE me one of these eggs as a reward for growing their business in one year in our chain of stores from 1 million to 3 million. At the time, they told me that they only made a dozen of them, but honestly, I think they probably made about 100 of them. Mine is #12. The movie people got #1 and #2, the company kept a couple and the rest were gifts from the Orrefors company to business associates. I do think they were sold for a short while in the Orrefors stores, and that is why I think there are probably about 100. If you turn it upside down, etched along the edge is lettering and numbers. The last set of numbers is your number for that limited item.
Having spent a lot of time in their crystal factory and others, I can tell you that it is extremely difficult to make a piece of crystal that is so thick (5" at the widest point) and so tall (7" to the point) without any flaws, bubbles, or fine fibers visible inside. Orrefors would have been meticulous about throwing out seconds on this item. They probably had to make a handful before they could put one into circulation. The rest would be thrown back into the kiln.
It would be wonderful to see this in resin or Lucite.
It weighs 10 pounds 3 ounces and would difficult to hurl through the air as in the movie!
Hope this helps.
