I want to know How to make 18carat gold Collar Necklet by hand.
That's kinda like "I want to know how to build a house", isn't it?
How youdo it depends on what kind you want to build. I would
recommend you pose that question on YouTube. They have many videos
on the subject of jewelry making. I'd suggest you watch a dozen or
so of them and get back to us when you have specific questions.
