Studio IPEye of Zul
The road not taken — scored higher on paper, needed surgery to get there.
Eye of Zul has no turntable footage — it was carried forward as a design candidate from the same study, not sent to render. Shown here: the original iris-candidate survey sheet and shared cutting diagram.

Design story
Eye of Zul scored higher than Dragon Eye on paper — ISO 85.6% brightness against a 6.9% window — but it wasn't written for corundum's index to begin with. Its pavilion was re-angled facet by facet, rescaling each tier's distance to hold the girdle line exactly.
The result is a legitimate, cuttable design in its own right, kept and offered as a second signature cut rather than shelved — proof that the same verification process holds up even on a design that needed real intervention to get there, not just the one that happened to need none.
Rough & material notes
- Same royal-blue Ceylon-style brief and rough spec as Dragon Eye.
- Originally written for a different refractive index than corundum's — its pavilion had to be re-angled before it was even a candidate.
