Graduated

from ArtisanPlugin.Scripting import GraduatedApi as graduated

A band whose section grows toward the centre stone, carrying a run of stones that shrink along the way - with prongs that taper to match.

Edit

The IGraduated handle has two sections; each setter regenerates the shank in place, re-baking stones, prongs and the under-bezel rail:

Section	What it edits
Shank	The two profiles the section morphs between (TopProfile and BottomProfile, each with profile asset, closing type and dimensions), plus cut bumping and opening margin
Gems	The run: stone count per side, start and end sizes, spacing, centre stone size, lift; the tapering prongs (heights, diameters, separations, over-girdle - each as a start/end pair); the under-bezel rail; and drills

Most prong and stone sizes come as start/end pairs - start is nearest the centre stone, end nearest the band - and are set in one call:

from ArtisanPlugin.Scripting import GraduatedApi as graduated, Transaction

ring = graduated.Selected()[0]
with Transaction.Begin("Five stones per side, steeper taper"):
    ring.Gems.SetNumberOfStones(5)
    ring.Gems.SetSizes(2.8, 1.3)              # centre-side, band-side
    ring.Gems.SetProngDiameters(0.80, 0.60)
