Vintage "Glitter Ball" Sterling Silver Necklace Rhinestone Ball Pendant.  Approximate measurements are: 

Chain- 15" long, closure says- Italy, 925

Ball- 1/4" & covered with Crystal Rhinestones 

This Choker Style Necklace is unbranded, but closure says- Italy, 925.  This is from my personal stash from the 1990's- I wore it to Dances, Proms, Weddings, Date, etc.  Great to layer with other jewelry- Simple, Danity, Elegant & Stunning!  Wear it with any outfit- dress it up or down.  Crystal Rhinestone Ball Pendant is removable & could be worn on a different Necklace or a Bracelet.  Condition is preowned with no chips or missing crystals.  The closure is in working order. The necklace has a little tarnish that could be cleaned- I left with original patina.  The necklace has a slight bend in it that really only shows when it's not being worn.  Prop is not included- Necklace & Pendant only.  Photos are part of description.  Really FUN Vintage Jewelry!!  J4
