12-30. Diamond(b) #07

Last diamond of the series, last series of the year!

I wanted to close with a resource from R. W.G Wyckoff.

R. Wyckoff is an American scientist and pioneer of X-ray crystallography who professor of microbiology and physics at the University of Arizona in Tucson in the early 1960’. I used several of his resources over the year, always a little anxious working with information going back so far in time.

This particular resource dated 1963 is a credit both to the quality of his work and the significance of his research that looks as new today as it did when it was completed

Original resource: Wyckoff R W G, Crystal Structures 1 (1963)

A mineral goes Sierpinski!

This is a front view of a diamond crystal unit cell. In the background, the mineral’s polyhedral structure. In the foreground, the carbon atoms in a 4/m symmetry pattern.

Is there such a thing as a visual digression?

Common practice in oral and written arts – I found myself carried into a visual digression! The diamond atoms’ symmetry led me to work on an optical illusion made famous by Hermann in the late 1800s. The “white dot in the black circle” after effect. Maybe it’s one of the reasons for diamond popularity – leaving an after-effect optical illusion in the viewer’s eye?



12-10. Vanadinite #1.

Vanadinite. Ancient lores say its crystal is beneficial to writers and boost creativity. They could add Kabuki opera and Juggling, so elegant and dynamic is its geometry and perfect prismatic hexagonal structure!

Vanadinite is unusual as a mineral as it’s only occurring as the result of alterations to a pre-existing material. Its bright-red and orange crystals often come perfectly formed and are sought after by many collectors.

It was first discovered in 1801 in Mexico. Vanadinite deposits have since been found in South America, Europe, Africa, and North America.

12-09. Hematite #7.

If we were to revisit cave painting a few thousand years forward, what would it look like? Hematite is still quite a source of inspiration!

12-08. Hematite #6.

Do you wonder what a hematite sounds like?

Its unit cell structure gives us the score, the notation, the key, even the notes’ succession and tempo!

I may rework this artwork as a multimedia file as soon as done with this project focusing uniquely on the visual aspect of the geometry of minerals. The challenge is intriguing!

12-07. Hematite #5.

Opposites attract each other!

Case in point – the stable and elegant structure of the hematite unit cell and the apparent chaos of its multitude of atoms. The result? A mineral that brings a beautiful variation of red as a powder but not much else in the tangible reality.
