Your necklaces are very pretty, but as 'blacksmith' said, you really can't see the detail very well in the photos. Some of you terms are incorrect, as well. I think what you want to get, and learn how to use, is a 'solder' gun. Also the correct term would be 'gold tone'.
Keep making jewelry. Look online for free 'tutorials'. The internet is loaded with free instructions. Go to 'youtube' for hundreds of free jewelry making instructional videos. Learn, practice, don't give up.
Good Luck, sweetie!
