The closest embossing index I can find in the book is [380]. However, this color is not listed for that index. The glass is remarkable in terms of its clarity. It looks like dark, dark lime green/light depression. Photo is taken in natural sunlight. Does anyone have a similiar piece? Is this [380]?
