Tiffany & Co. Large Sterling Silver Diamond Cross Pendant 18" Necklace - Authentic - The necklace is still available without the diamond on the Tiffany & Co website - the diamond version has been discontinued — on the Tiffany website currently - MSRP for version without the diamond is $450 and was originally $750 with the diamond.. – This exact style is discontinued with the middle diamond — purchased 5 years (so I no longer have the receipt) - I got it for my birthday when I turned 30…. Additionally, you can compare the brand engravings that say Tiffany & Co - this engraving is found in two places on the necklace -1) the necklace clasp and 2) on the back of the cross necklace, (although it’s a little blurry in the photo for the back of the cross). These markings are the same as the one in the store currently if you wanted to compare my photos the one in the store that does not have the diamond. 😊 -The Cross on 18" Sterling Silver chain and is marked Tiffany&Co. Ag 925. - The cross is 20mm by 28mm. Jewelry box included
