There are all kinds of use for open jump rings and click/lock are the best because they enable you to secure the rings without the mess or hassle of soldering.
Gold fill is far superior to gold plating as it is a significant layer of gold (around 5% of the weight) which is much more resistant to scratching etc than the layer used for plating which is measured in microns.
They are 0.64mm gauge (22ga).
If you haven't used these type of rings before, they click shut simply by manipulating them back and forth. Search YouTube for various instructional videos!
