Last night I made 3 pendants with 14k gold filled wire and it reminded me what a pleasure it is to use. I love sterling too, but the gold filled has a certain quality I can't really describe. You don't really get any second chances with it, despite using the 'soft' as the more it is handled, the harder it sets. As it also costs heaps, it can be quite daunting to plunge into a new design not knowing if you have enough wire cut and so on. When it's polished, 14k has this marvellous deep colour and I think it really helps to frame natural gemstones.
