This is a Tiffany & Co. Open Heart silk cord choker. The silk cord is removable, and the color is black, although it may appear as a very dark navy blue depending on the lighting. I am selling this as I received it from someone else and wore it a few times before storing it. I am selling it without the box, Tiffany & Co. pouch, or warranty card, so the only item for sale is the choker in the photos. The size of the open heart is approximately 35mm, and the silk cord length is approximately 44cm. Please note that there may be slight variations due to amateur measurements. The back is stamped with Tiffany & Co., Elsa Peretti, 925, and Spain. There are some scratches, small dents, and slight tarnish characteristic of silver, but I didn't notice them while wearing it. Please check the photos for the condition, and refrain from purchasing if you have any concerns. Returns are not accepted to prevent product substitution. Thank you for looking.
