awesome lamp

its a 2 piece lamp. its hand spun pottery. it is also hand carved. it has marbles, blue, green, and a rootbeer color, to help accent the light. i do believe it to be at least 100 years old. they had used a black resin to glue the marbles in. i'm almost positive that it was made to use with a candle, not modern lighting. i do have a light bulb inside it to show off the holes and marbles. the piece is in mint condition. no makers marks. any help of who made it and what it might cost would be greatly appreciated. i paid 2 dollars at a garage sale. thank you
