My Favorite Lamp

I purchased this lamp at a second hand store. I fell in love with it as soon as I saw it. The 3 cups that hang they turn on, It's like pieces of cut glass on the cups that make all these pretty colors stand out. It has a glass table. It is all one piece, It is very heavy, I would love to know more info, if anyone can help me out. I would like to know what the value of this lamp would be. About 3 years ago a friend of the family came over with some friends & they loved the lamp. One of the ladies offered me $600.00 for the lamp, but I told her it was not for sale. I have had this lamp for about 10 years..
