The white gold looks like sunlight glinting off water.
Now, if you are out treasure hunting, and you find something that looks like this for $25 stuck in the costume jewelry section you know to grab it FAST! (We can dream, right? I figure, crazy things like that have happened to other people, why not to us?!)
The next time you get the opportunity to look at a famous designer piece, take it immediately. Keep adding to your jewelry knowledge. Even if it seems trivial, it's part of the larger picture and worth doing. You'll never know how great the rewards can be.
