The Topaz was launched in May 2012 and has been kept fairly secretive. Reports said it was designed by Tim Heywood of Britain, who has several other credits on the world's largest yachts list.
It is speculated to have a price tag ranging from $470 million to $626 million, weighs 12,000 tons, and is thought to have six cabins and with accommodations for 12 guests.
The Topaz was built by Lurssen Yachts and had to be relocated from a 557-foot dry dock in the middle of construction due to its massive size. It is currently unavailable for charter.
