The illusion of cubes

[RoughCreations]

Was flicking through my Youtube feed (as I do) when I came across this simple hexagonal design, with only 12 facets in total (see below). I noticed that the two tiers at 30 degrees gave massive windowing in Gem Cut Studio (GCS), at least for quartz - but perhaps this is a part of the design element? I re-cut the two tiers at 38 degrees in GCS and got much better performance, but maybe this sacrifices the cube optical effect/illusion? Has anyone cut this design or similar? I thought it would be good for rough too thin/too dark for a standard cut. Maybe also it relies on a very unsaturated coloured stone to get the best cube effect.

I am not sure of the copyright of this design, but the first video has a screen showing the basic cutting instructions about 42 seconds in.

I recently cut a Cube Illusion myself as an experiment in light-coloured Tanga garnet, size is 7.5mm across the flats. I am currently cutting a colourless topaz in this design for comparison.

That's amazing.

That's come up well RC. I have that design on the 'to do' list, but haven't quite got there yet, maybe when i get back from my current trip.

I recommended it highly, something different, quick to cut for a change, not many ways to go wrong.

It looks good, I wonder how one would look in a pendant.

Pretty good I reckon, you could just have a thin bezel all round, it would be a bit funky though for the jeweller setting it, as the girdle is a zig-zag!
