I spotted these rings on the Beso Beso website and stopped in my tracks. What is the source of such glimmering, richly saturated hues? It appears to be “sparkling Brazillian semi-precious miniature-crystalline amethyst stones”. That is one stunning shade of magenta. Of course nature is responsible for it! (love the geometric shapes as well…)
