The 1” x ¾” setting is gold tone with a very dark green stone (cold to the touch). I believe it is soap stone but not 100 % sure. Very nice looking with an Anson maker’s mark on back of cufflink. They are in good condition and ready to wear with your French cuff shirt.
All my cufflinks and jewelry are sold in used, pre-owned condition. Vintage and Antique items by nature have some wear, imperfections and signs of use and age.
