The wall has twelve foundation stones, and on these are written the names of the Twelve Apostles. Revelation lacks a list of the names of the Twelve Apostles, and does not describe which name is inscribed on which foundation stone, or if all of the names are inscribed on all of the foundation stones, so that aspect of the arrangement is open to speculation. One scholar hold that Judas Iscariot's name is absent from the foundations, replaced by that of another Apostle.
These foundation stones are adorned with twelve types of precious stones. In modern times, the precise identification of all these precious stones is not certain, as several of the ancient names may refer to several different types of stones, or may no longer refer to the same kinds of stones that they did at the time of Revelation's writing. Also, the layout of the precious stones is contested. All of the precious stones could adorn each foundation stone, either in layers or mixed together some other way, or just one unique type of stone could adorn each separate foundation stone.
