THIS IS A SET OF CANDLE HOLDERS YOU DONT SEE EVERYDAY.  THEY ARE OF VERY THICK GLASS...BELL SHAPE...ARE TWO PIECES CONNECTED WITH A SILVER ATTACHED ADAPTER.  YOU CAN ALSO REVERSE THEM FOR A DIFFERENT LOOK.   THEY MEASURE 6 1/2 INCHES TALL X 2 7/8 INCHES IN DIAMETER WHEN THE BELL SHAPE...AND 3 1/2 INCHES IN DIAMETER WHEN REVERSED.  BECAUSE EACH PIECE HAS A FLAT SURFACE YOU CAN ALSO TAKE THE PIECES APART AND USE EACH PIECE AS A SEPERATE CANDLE HOLDER....THEN GIVING YOU DIFFERENT HEIGHTS OF HOLDERS (so a set of 4).  
THE CANDLE SIZE IF YOU INSERT IT INTO THE SILVER PART MEASURES A LITTLE OVER 1 1/4 INCHES.  THE WIDER PIECE CAN TAKE A CANDLE UP TO 5/8 INCHES.  I BELIEVE THE BELL SHAPE HOLDER CAN TAKE A CANDLE OF THE SAME SIZE OR A TAPERED CANDLE EASILY.  
THE ONE CANDLE HOLDER HAS A SCRATCH ON THE BELL SHAPE HOLDER.  THE OTHER CANDLE HOLDER HAS A VERY TINY (a pin head) INDENTATION IN IT.  THESE ISSUES ARE VERY MINOR BEINGS THESE PIECES ARE SO DECORATIVE AND VERSITILE.  
THESE CANDLE HOLDERS WERE GIVEN TO ME 30 YEARS AGO BY MY AUNT WHEN I GOT MARRIED. THEY HAVE ALWAYS BEEN A NICE ADDITION TO OUR HOLIDAY TABLE SETTINGS.  BEINGS ALL THE KIDS ARE NOW GONE I DONT ENTERTAIN MUCH ANYMORE.  TIME FOR MY TREASURES TO FIND A GOOD HOME. 

LET ME KNOW IF YOU NEED BETTER PHOTOS OF THEM.  BECAUSE THESE CANDLE HOLDERS ARE MADE OF VERY THICK GLASS … BOTH OF THEM WEIGH IN AT 2 LBS 13.7OZ WITHOUT WRAPPING AND BOX
