Lamp

 This Lamp was given to me by my Father in-law  abour 2 years ago im not sure when it was made or really anything about the lamp but it is very beautiful.The lamp  has 4 porcelain women around the bottom and a light that shines down onto the women and another light above that that,that's under the lamp shade all the lights are in working order.I looked on the bottom of one of the porcelain women and it says Andrea by Sadek but nothing under the lamp itself and no year and thats really about all I know about this lamp.

If any one has any information about whenthe lamp could have been made and by who or about how much it could be worth would be appreciated

Thank You
