JERUSALEM, the CRYSTAL CITY.

CRYSTAL denotes transparency, it is a transparent mineral. The variety of QUARTZ in its PUREST FORM, is composed of SILICON and OXIGEN. Presently is called ROCK CRYSTAL. It is found in its characteristic SIX-SIDED form in nearly all kinds of rock and is colorless, clear and glassy in appearance. ROCK CRYSTAL is much harder than other common minerals.
In the Scriptures, we can find the description of the crystal city of Jerusalem and its surroundings. It says as follows:
Revelation, chapter 4 : 2) John saw THE THRONE OF GOD IN HEAVEN.
                                    4) The TWENTY FOUR ELDERS
                                    6) The FOUR BEASTS FULL OF EYES BEFORE and BEHIND.
                                  10) The ELDERS LAY DOWN THEIR CROWNS, and WORSHIP GOD
                                         that SAT ON THE THRONE.
After this  (the angel of the church of Sardis is reproved, exhorted to repent, and threatened if he do not repent; the angel of the church of Philadelphia is approved for his diligence and patience; the angel of Laodicea rebuked, for being neither hot nor cold, and admonished to be more zealous. CHRIST stood at the DOOR and KNOCKED)  and, behold, a DOOR WAS OPENED IN HEAVEN : and the FIRST VOICE which I heard WAS AS IT WERE OF A TRUMPET TALKING WITH ME; which said : "COME UP CLOSER TOWARDS THIS PLACE and I WILL SHOW YOU THINGS WHICH MUST BE HEREAFTER."
And IMMEDIATELY I WAS IN THE SPIRIT : and, behold, A THRONE WAS SET IN HEAVEN,
and ONE SAT ON THE THRONE. And HE THAT SAT WAS TO LOOK UPON like a JASPER
and a SARDINE STONE : and THERE WAS A RAINBOW ROUND ABOUT the THRONE WERE TWENTY FOUR SEATS : and UPON THE SEATS I SAW TWENTY FOUR ELDERS
sitting, CLOTHED IN WHITE RAIMENT; and they had ON THEIR HEADS CROWNS OF GOLD.
And OUT OF THE THRONE proceeded LIGHTNINGS and THUNDERS and VOICES : and THERE WERE SEVEN LAMPS OF FIRE BURNING BEFORE THE THRONE, which are THE
SEVEN SPIRITS OF GOD.
