I wish I could find out more about this bowl.  I was not able to find any markings or pictures of this exact piece.  It measures 10" wide and is 5" tall.  I believe it may be  a salad bowl.   It has diamond cuts that give it a 3D appearance in the light.  Please see photos as part of the description.  It is in excellent condition except for I feel a slight rough spot on the rim of the bowl but the chip is not noticable and does not show up in photos.  Please email me if you would like more information or if you have more information about this piece.
