EMERALDS: A PASSIONATE GUIDE - THE EMERALDS, THE PEOPLE, THEIR SECRETS by Ronald Ringsrud.  Green View Press, 2009. Large hardcover, 382 pages, illustrated.  Very Good condition.  A couple bumps at the head and tail of the spine.  The half-title page has a long vertical crease.  A handful of other page sets have smaller creases (around four inches long), but the text is still quite legible.  The book is otherwise clean, tight and unmarked.  The dust jacket has a tiny bit of edge-wear at the head of the spine and at one corner.  It's otherwise clean and sharp.  A nice copy in spite of flaws.
