Persepolis Hex Sign

The back reads:

By stone and star, by hand and heart,
I call the strength that does not part.
Like columns rising, calm and true,
May balance stand in all I do.

Let patience root, let wisdom stay,
Let beauty hold the weight of days.
What I build now, let it endure,
With steady hands and purpose sure.

So it stands. So it holds. So it remains.
