Isotropic Stones for the New Jerusalem

An old friend share this on his facebook page. Just fascinating.

I do not believe you can and should use science discoveries to prove the Bible, but I am just amazed about the isotropic properties of the twelve stones designated for the New Jerusalem in the Bible.

For a long time I had wondered why diamonds were not included in this new city. Well with a little additional knowledge, it would simply be less beautiful and harmonious.
