These goldtone cufflinks have an "S" on the back which leads me to conclude they are Swank. The white stone I am leaning toward mother of pearl. They are 1 inch x 5/8ths and in good condition. Very minimal scratching like they were never worn. They are very light so they would be very comfortable on a light weight shirt, or even a ladies french cuffed blouse. The shading and unevenness of the photos are due to my photography skills and not the piece.. We must collect 6% Pennsylvania Sales Tax at checkout. Thanks for stopping by!
