3D CAD designer for ring mold

Looking for a 3 D CAD Designer with experience in jewelry making to draft a wedding band for my fiancé - similar to the attached image, just thicker band than image show with prongs for a an elongated diamond cut stone to sit in the center (to be flush with the ring, not set up on top like an engagement ring) ~ an overall more masculine feel and “natural” edges that aren’t perfectly symmetrical (think the edges like the shape of a branch).
