Chalcedony - The Secret Stone

The third foundational stone of the New Jerusalem in Revelation 21:19 (NIV) is the Chalcedony. (See also The Minerals of Revelation). It is a variety of Silicon Quartz (SiO2) characterized by its fineness of grain and brightness of color. When Quartz forms as finely grained micro-crystals, it is known as Chalcedony. Chalcedony really is a family of gems that includes Agate, Jasper, Carnelian, and Onyx. It is translucent and has a waxy luster. It can assume a wide range of colors, but the color most likely represented in Revelation is a grayish-blue.

Blue Chalcedony

The Greek word "chalkedon" is used in the Book of Revelation and means a precious stone of misty grey color. It comes from "chalkos" meaning brass, and "eidos" meaning the external or outward appearance, form, figure or shape. It is possible the chalcedony shined like brass. It is translated into Latin as "calcedonius," where we get the name "chalcedony," and is found only once in the Biblical text. Chalcedony is derived from Chalcedon, in Bithynia (Turkey), where the ancients obtained the stone.

Chalcedony is not found in the Breastplate of the High Priest (Exodus 28:15ff - NKJV) but is thought by some to have been the same stone as the Agate, found in the Third Row of the Breastplate. If this is correct, then the Chalcedony(Agate) would represent Jacob's eight born son Asher by birth order and Joseph's son Manasseh by the order of the camp. Chalcedony has also been said to represent the apostle Andrew, the brother of Simon Peter.

Chalcedony Represents Our Christian Living
That Which We Do in Secret
Be it Fasting, Prayer or Acts of Service

The biblical meaning behind the Chalcedony gemstone is our faithful service to the Lord, done in secret (Matthew 6:6 - NIV). When we go out into the world, our goodness is revealed and we can shine but we must resist excessive praise with great strength, lest we boast. Blue Chalcedony encourages reflection and meditation on the Divine and its light blue color represents heaven and communication with the Spirit of God.

...so that your giving may be in secret... (Matthew 6:4)
...when you pray, go into your room, close the door and pray... (Matthew 6:6)
...so it will not be obvious to men that you are fasting... (Matthew 6:18)

...but only to your Father, who is unseen; then your Father, who sees what is done in secret, will reward you.

Philippians 4:12-13 (NIV) - I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. 13 I can do everything through Him who gives me strength.
