In many regards this is an easier design than the SRB, but we are now introducing the concept of a step cut crown and some facets need a light touch. Also notice that the pavilion has four very steep “wing” facets. This design follows the overall Barion design methodology using steep wing facets and using a step cut crown. Barions are very bright sparkly stones
Note that the main facets do not meet the girdle and only half touch the #4 wing facets, the other half meet only at the culet and are otherwise free floating.
The crown needs a well aligned transfer to allow for the steps to meet well. As you have very large girdle facets, the alignment post transfer should be quite easy. Note that the 2nd crown tier is somewhat free-floating and does not have a clear stopping point. The 15 degree tier two facets overcut very easily, especially the tiny D corners (skip D until 1200, possibly even 3000 grit; even at 1200 these will come in very, very fast).
