Crystolite is one of the most popular and collectible patterns Heisey produced.  The Crystolite pattern (#1503) was manufactured from 1938 until 1957.  Here is a very beautiful Crystolite jelly/jam jar, with the cover and a ladle.   It is marked with the Heisey trademark diamond H on the bottom.  The ladle is not Heisey but is a scarce vintage Duncan and Miller mayonnaise ladle.  The jelly/jam jar measures about 5 ¼” high and 4” in diameter.  It is in excellent vintage condition with no chips or nicks.  The Duncan and Miller ladle is about 4 ¾” from end to end, with no condition issues.  This beautiful Crystolite jam/jelly jar would look great in your Heisey or vintage glass curio.
