@05ad22c7 Igen; the first picture is a randomly published daily facet design from the DVUE database together with diagram link.

Gif and graph I made using Gem Cut Studio, my preferred design software. It can model material performance to accurately show how light bounces within stone and at what angles.

Graph shows performance of the stone in terms of light return and light windowing face up, and then tilted 30 degrees up and 30 degrees left.

My TL also has videos of some designs cut in real.

That’s very cool. Do you ever cut the gems to the patterns i. The CAD drawings?  And how is that done? 

 @05ad22c7 Very often. Most of the videos you can find in my feed show the result of a diagram. The CAD printout itself functions as manual operator instructions for a generic faceting machine.

Here is one from a few months ago. It’s my take on the Crisantemo cut by Marco Voltolini. It uses some of the culet and frosted facet tricks I picked up studying Vietnamese cutter Phan Thanh Trung.

Wow. That’s amazing. That’s quite the talent.
