tiny sculpt ring parts

hi I want to make jewellery with gems. I have perfect ideas but I cant find a way to make a diamond ring's part "which holds the stone in place".

here is a sample link to understand what I mean because I dont know the name: http://www.diamonddealerdirect.co.uk/images_diamond/engagement_rings/emerald_cut/diamond_l/diamond_ring_CD006E.jpg

I have no idea about maya and has a few knowledge about sculpting. I can do my best with a good tutorial or a good teacher. just need help please.

I do this sort of stuff using blender. I made such a ring sculpt map which took me about 10-15 minutes only:
