Details
The Tiffany has an uneventful history, belonging to Tiffany’s since it was unearthed.
OK, what you see above is the current model of the Tiffany, not the brownish replica I had before. It’s amazing what can be done to update a model after 25 years of technological developments. No more tracing paper, this was done using my latest techniques on the computer.
One of the things I recently discovered is that the pavilion main angles can be accurately determined (within about ±0.5°) by looking at the reflection of the culet facet, and its position relative to the facet itself and the girdle. More on this in the Regent discussion.
