Revelation Jerusalem is the golden city, the true envy of the world. Tradition has it that it's bathed in eternal light, that the unworthy are struck down on its doorstep, and that a sense of holiness pervades the place. But more importantly, it's really a golden city. Sounds expensive, but just how expensive?

Required WB input: order of magnitude estimate of cost. I'd prefer the estimate in 2016 US Dollars or as a ratio to US Annual GDP at $17.4 trillion.

Here are the salient features we are concerned with:

• The Sea of Crystal -- A reflecting pool, roughly the size of the Reflecting Pool (618 m x 51m). Must be covered throughout in inlaid emerald and topaz.
  

• The Statue of the God-Emperor on a Throne, roughly similar in size with the Statue of Zeus at Olympia, about 13 m tall. (Can be) hollow or non-gold support structure, but both statue and throne at least 1" thick high quality gold, encrusted with precious gems, like thus:

• The Twelve Gates, studded in pearls spaced such that they blend seamlessly into each other (or a single pearly slab if possible), each roughly the size of the Ishtar gate, looks about 5m x 12m.
  

• The Golden City: All buildings covered in gold foil (approximately 1000 buildings, average 400 sq. m of roof each)
  

• Shining City Walls, covered in Jasper (a semi-precious stone) alternating green and red. This is only to cover the wall, the foundation and structure can be a regular construction material. The wall is 10 m high and ~30 km long.
  

It it is possible to generate these via industrial manufacture, I'd prefer that over mining. If it is possible to break down the individual highlighted items by price, I'd love to see that, but it is not mandatory. I may accept partial answers if one or more of the estimates are impossible to produce. If multiple estimates are available (say depending on carat size), I prefer the lower cost one. Rough Fermi-style order-of-magnitude-estimates ok.
