also to comment on the casting option.... casting is capable of producing MUCH finer details than the ring you posted a photo of. lots of fun to do, but does take a little more than $1500 to get set up unless you can find a local jeweler going out of business or just clearing out some equipment. then you can find some great deals. I managed to find one here 4 years ago and got the whole shop for $1400.
Thanks a lor for also commenting about that option. Actually that is what i am focused on these 2 days. Even i have made a list of what i need for casting. But i am still curious about the details. To make sure that we are talking about the same casting method, we are talking about delft clay sand method right??? (just used on this video https://www.youtube.com/watch?v=K0sCDTRwMwg )
May be because i am not familier about casting, it still seems i can not have a detailed work like above? I am not an expert, i dont want to be rude but that is what i am thinking. If you are pointing the much finer detail casting on an another method, please tell me. May be you are referring the wax method first than sand method.
