Stone, heavy, opaque and certain, is a symbol of a constant through time, beyond humanity itself.

The Ten Commandments are written on stone, exuding permanence beyond human life. Glass by contrast seems transparent, delicate, fragile and ephemeral like us.

The two seem to be completely different substances, but glass is born of stone. They are like father and son, they have the same DNA, although they look completely different.

God-like, with DNA inherited from an omnipotent father, it nevertheless takes on a completely different form, independent and self-reliant.

It represents the chain of life that moves far and becomes the template for another. It is always beyond our control what will become good or bad.

伊達冠石（Daté Kan Stones）” is the name of stones.
