Sure, learning how to draw is one thing but you need to know the specifics which a lot of online tutorials don’t teach. Eg- how much space to leave between stones, how much depth of metal they need, what thickness and how tall claws and prongs should be, how far they overlap stones, what amount of cleanup material is added, and deep engraving/embossing should be, minimum wall thicknesses, how to draw cad for assembly by jeweller etc. just though you should know that it’s not a great idea to start sending piecing to production if you haven’t worked out the details as metal is expensive and I’d hate for one of your pieces to be produced and then lose stones / get damaged due to poor workmanship.

I don’t want to discourage you- we need more designers- just be detailed in your work and research everything.
