Today the JAC Oldies but Goodies Challenge is about ice.
According to Wikipedia ice is "water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color".
Although it would be great to work with icicles - I mean, have you seen some of those beauties - it might be a little difficult in jewelry, but quartz, rock crystal and clear glass crystals have almost the same effect as you can see in all the items in this thread.
Of course I do have a sneak peek for you again.
