Fostoria Glass made two cut crystal patterns named Cynthia, one in the mid 1920s and this later one, produced from 1938 to about 1943 in dinnerware and through the early 1960s in stemware. What makes this later Cynthia so special are the blanks Fostoria used, the graceful Coronet for dinnerware and accessory pieces, and Sceptre for stemware.
Coronet has three wavy lines just inside the rims and the handles on pieces have a curled appearance like a ram’s horn.
Sceptre has a stacked group of serrated wafers at the top like a royal sceptre and is the same stem line Fostoria used for Lido and Romance.
Fostoria made a fairly small line of tableware, basically a luncheon set with no dinner plate and no bowls for individual place settings. (Replacements mentions a dinner plate out of stock; my Long and Seate Fostoria book omits it.) There are several lovely accessory pieces including three candle holders.
Of course you can choose among multiple relish dishes plus small bowls meant for olives, pickles or celery, sweetmeats (dinner mints) and four large bowls both with and without handles. (Unfortunately my site is acting up and I can’t upload the photo of our 2-handled bowl.)
Fun serving pieces include special plates for lemons, cheese and cracker set (these are quite useful by the way), ice bucket, cruet with stopper, mayo set and a pitcher. I particularly like the little 2-handled bon bon and its larger cousin the muffin tray.
My experience is that Cynthia is not hard to find. We bought a very large set of stemware at an auction which got me interested in the pattern, and later found quite a few accessory pieces. At the moment (late October 2022) Replacements has most pieces in stock and eBay has many listings for stemware. Most pieces are not super expensive either, which means you can enjoy a set of stems or accessories without spending more than you would for contemporary quality crystal.
