== Picture of the Year candidate == 

  
 This image is a candidate for Picture of the Year over at Commons, and I just wanted to bring it to the attention of this article's caretakers . At a larger size, it shows quite a lot of detail. In fact, I wonder whether instead of so many small images in galleries, the article might be better served with fewer images, but at least one at a larger size that would show the crystalline structure better. I don't watch this page, so just dropping by.
