Tiffany & Co. Schlumberger 18k and platinum 6-row diamond rope ring 5.25

Tiffany & Co. Schlumberger 18k yellow gold, platinum, and diamond 6-row rope ring. This item was resized to a size 5.25 so there is a line of demarcation that is a lighter shade of gold from where it was cut and soldered back together. It is hard to pick up on in photos because it’s small, but it is there in the main photo. Item will come with Tiffany ring box. The 6-row style of this ring has been discontinued. All questions welcome.
