We have a bunch of left over ends and pieces of crystal cup chain here at the shop. some of it is quite old Swarovski stock. It is a mixed bag really, the length of pieces varies. Size of stone is fairly consistent looks like 3-4mm on most of it. Overall I am going to say 18" is a common size to these pieces but they might be as long as 40" and as small as a couple inches. It is a colorful mix. Will contain a large variety of colors which may include clear, red, pink, purple, cobalt, light green, aqua, solid black, some solid white. I am measuring this by weight 50 grams. When you line that up it will be about 12 feet end to end. Might be a tad less if I have some chunky stuff and a tad more with lighter chain pieces but it seems pretty consistent. The pictures are a good representative of what you will get. This was an actual lot and they are pretty similar, some variation in colors, but size and style similar.
