This is my latest laminated amethyst I have finished
With this one I made the internal cavity as big as was possible without loosing the stones integrity.
What I also did this time, is to increase the crown facets to 40º and keep them high.
Then I faceted the top in a slight dome, like oº, then 10º, then 20º.
What that did was act as a mini magnifying glass, so the center ball appears bigger.
Also, I faceted eight main facets, instead of four. I think this will be about the maximum before the flower effect is lost and it starts looking like a bicycle sprocket.
This is a view of the pavilion.
This little video shows the 'mercury effect' that the little gold ball has when the stone is slightly shaken around, as if it were set in a ring, say.
