Measured from the ring above, not typed in. Change anything and every number moves with it.
Solved, not drawn
Every frame is real geometry.
The shank is a profile swept around your ring size. The claws sit outside the girdle and fold over the crown, where a bench would put them. The mesh is watertight, which is what makes its volume mean anything — and the volume is where the price comes from.
Priced from metal, not a table
A number you can take to a bench.
Mesh becomes volume, volume times the density of the alloy becomes grams, grams meet a rate card. Narrow the band and the price falls, because there is less platinum in it. Nothing in that chain is looked up or estimated, which is why the figure survives contact with a real quote.
Craftable or clearly labelled
It will tell you what cannot be made.
Under 1.6 mm a shank wears thin within a decade. An elongated stone needs four claws, because its points are the vulnerable part. You are told while you are still designing — not after you have fallen for something a workshop will refuse.
Every design has an address
Share the ring, not a screenshot.
A link carries the design itself, readable in the URL. Whoever opens it gets your exact piece — same geometry, same price — and can change it and send it back. That is the point: this is how two people decide together.
