I have seen many attractive SW Indian pieces where there are deep evenly spaced grooves radiating out from the bezelled center stone to the edge of the piece. The grooves then are darkened with liver of sulfer with the top silver brightly polished. The grooves add a lot to the piece and focus one’s attention on the stone. The grooves are deep and uniform, much deeper than normal indian hand stamps.
Does anyone know the technique used to create these grooves? Are they chiselled, engraved with a heavy engraver, or is the piece caste with the groves. I have tried cold stamping, but it’s difficult to get nice grooves spaced evenly with uniform depth.
Any comments would be appreciated.
