And back to metals again...

As you can't tell I am an information junkie. So again, my husband picked me up another book from the library - one of the Eyewitness books about gemstones. Of course, I had to look at the pages on my favorite metal for jewelry, silver.

Did you know that the best silver comes from a mine in Norway? At a mine in Kongsberg, Norway, dendritic silver is found naturally in the shape of twisted wire. Convenient… (now of course I want to see how I can get my hands on some - will let you know)

Silver in its natural purity tarnishes and is too soft to work into jewelry, so is alloyed with other metals, often copper or gold. The standards are Sterling silver at 92 ½ percent or more pure silver (often with copper), Britannia Silver with 95 percent or more pure silver. Additionally, one ancient alloy contains 20 to 25 percent silver alloyed with gold and is called electrum.

Personally, I like the coloring of silver and its starkness against other colors. Just suits my work well.
