Iris, also known as Iris and Herringbone, was made by Jeannette Glass from 1928 to 1932, again in some pieces and colors in the 50's and the 70's.   All of the pieces in the line were made in crystal, most in iridescent (which looks like carnival glass and is often mistaken for that) and a few pieces in transparent green and pink all of which are hard to find and thus somewhat expensive.  The newer pieces are often 2 colors.  In iridescentl, the pieces that will be the hardest to find are the demitasse cup and saucer, fruit or nut set (a large bowl with metal insert at the bottom for nut picks or fruit knives), the 5-1/2" goblets and the 4" footed sherbet.   (We are sorry but we cannot email photos of each and every piece of glass for sale.   If you need to see a picture of an item to know what it looks like we highly recommend The Collector's Encyclopedia of Depression Glass by Gene Florence.)
