This work by Arnaldon Pomodoro (1965) is the very essence of "space jewellery" to me.
Space in regard to the physical area it occupies, and the sense of the futuristic.
In saying this, I'm diluting the intention of the artist. But how we react to an art piece comes from our way of viewing the world.
I view the world through the lens of jewellery.
This image does the work no justice. It is remarkable in its jem-like qualities.
