Although known for his stained glass windows, leaded glass lamps and favrile glass vessels, it was not until 1902 that Louis Comfort Tiffany embarked on jewelry design.  This division was located at Tiffany Furnaces until 1907 when it was purchased by Tiffany & Co. with a special department set up at the Tiffany & Co. store. From that date until the workshop closed in 1933, all of Louis Comfort Tiffany's jewelry was stamped with the Tiffany & Co. mark. This ring is characteristic of the jewelry made under Tiffany's direction and dates to c. 1915 to 1920, when Meta Overbeck was in charge of the department.  Jewelry created while she was director is bolder in conception both in design and use of gemstones. 

Louis Comfort Tiffany worked with George Frederick Kunz, the gem expert at Tiffany & Co., who traveled the world in search of rare and beautiful gemstones.  It was he who would have found this rare 11.05 carat natural color fancy intense yellow diamond and it was Tiffany's keen eye for color that paired it with fancy-cut emeralds.  The juxtaposition of deep yellow and dark green is the palette of a painter who understood the subtleties of color.  This magnificent stone is heir to other important Tiffany yellow diamonds including the 30.00 carat Brunswick Diamond and the 128.54 carat Tiffany Diamond that is still in the company's collection.   

The mounting on this ring is designed with filigree work, most likely inspired by items in Tiffany's collection at his home, Laurelton Hall, which included a Hindu silver neck ornament and an Albanian buckle. In this technique, two thin wires are twisted together in a rope-like manner, then fashioned into rosettes, scrolls or coiled wire as on this ring.  The rope-like motifs encircle the diamond and border the emeralds with the ornamentation continuing as strips on the shank, terminating with incised bands. The decoration is reiterated on the underside of the diamond, encircling the culet; a detail that only a superb designer would create.

I have only seen one other Louis Comfort Tiffany ring with yellow diamonds that is now in the collection of the Louis Comfort Tiffany Museum in Japan. That ring has three smaller diamonds but this ring, with one important stone, has an amazing quality about it; my impression of the diamond the first time I saw it.  This ring is an iconic jewel and ranks among the best not only of Tiffany's designs but also of American jewelry, rivaling that of European makers.
