You can find cutting instructions for the Aqua Cisir here.
In spite of the Aqua Cisir’s simple appearance, this cut isn’t intended for beginners. In terms of skill and technique requirements, I’d rate this design at about a 6 on a scale of 10.
The corners are designed to “float.” If your L/W (length to width ratio) deviates somewhat from 2:1, it won’t hurt anything. However, you’ll have to make corresponding adjustments to the affected angles.
Depending on your skill and the accuracy of your machine, you might find the keel a little hard to meet. The long keel facets may also cause problems for novices due to chipping on the edges, especially with quartz.
This cut has exceptional flash and yield. For intermediate to professional faceters, this is a very fast design to cut.
Enjoy cutting your “Aqua Cisir.”
