Movoto looked at the potential cost of Superman’s Fortress of Solitude. And while depictions of the fortress vary, Movoto assumes the cost of the crystal-style fortress could run up to $814 trillion.
Part of the price is the necessity of getting that much diamond-like material. From Movoto:
Most—but not all—versions of the Fortress of Solitude are constructed out of a Kryptonian crystalline material known a sunstone. Since there are no Kryptonian crystals in the real world, I needed to pick a substance as a stand-in. Some common crystals are: diamonds, salt, and snowflakes.
I can tell you right now that Superman doesn’t have a citadel made from salt or snowflakes.
I’ve never purchased an engagement ring, but based on the sheer amount of stuff you need to know before you buy a diamond, I might never get engaged. In other words, without Kryptonian diamonds handy, I went with the kind that is actually found on Earth.
Superman returns to movie screens in “Man of Steel,” releasing June 14.
