Beryl actually represents a group of stones including aquamarine, emerald,heliodor andmorganite. I am not sure which one of these stones John was speaking of, but I believe it wasaquamarine. The beryl of choice during that time was aquamarine, so he could have been speaking of that particular stone. Seamen carried aquamarine in ancient times to protect them from drowning and promote safe travel. This stone is said to enhance spiritual communication, which would make it a great stone for the foundation.
Aquamarine is also an excellent stone for helping you overcome being judgmental. We should look at all people with love and understanding, and get to know them, instead of passing judgement at first sight. Everyone sins, and we should not be judging others for their sins before looking into ourselves. Aquamarine is great for helping you realize your inner-most truths. For physical healing, this stone has been used for respiratory illnesses, skin conditions and eye problems.
