Some photos :
A piece of antimony, an ingot of 99 % purity.
I witnessed several changes in the directions of the crystallizations, also in the colours that can show the regulus (in the star).
A regulus broken in the vertical sense.
In the horizontal sense now.
Home made tools. An evening for each.
The Regulus and the radiance in it (this one is not "updated").
The same regulus, I underlined the star and the cave.
Broken in two.
