Goldsmithing is based on a number of techniques that have not changed over the centuries.
One of them is operating a hand saw with a hair blade. You need not only practice, but also the ability to use various tools of a similar design. The openwork floral patterns in the drawing were not made in the 3D program, but were cut entirely by hand with a saw blade.
The ring is made of pink palladium gold 750, which is my proprietary alloy with unusual properties. High-quality diamonds with a total weight of 1 ct were selected for this project.
