There are four rings in the collection that are not costume. They are gold plated sterling silver with semi-precious stones. The four rings are: rose quartz, clear quartz, malachite and amethyst which, in my opinion, is the most stunning. There is also a grasshopper stick pin made with lapis.
My advice is get yourself a piece while it's still in stores and on line. The prices are very reasonable and the pieces are definitely collectible. Each piece is marked 'Coach' and comes with a felt pouch with a sunburst design and the names of Coach and Tony Duquette. There is also a book about the collection for sale. My top picks are the sunburst pendant necklace and the sunburst amethyst ring. I have been drooling over sunburst wall mirrors for a long time and now I can wear a fabulous miniature replica of one around my neck (sans the mirror--the center is open)!
