14k gold - not stamped but I got this made by a local jeweler in town. My ring finger is a size 5.25 but as you can see I am able to fit it on all of my fingers except my pinky. It is adjustable because of the design. Genuine Topaz and Citrine. Designed by me. Worn just a couple of times. Smoke free home. Comes in a ring box. Will ship next day. Not Helzberg - just added tag for exposure. When purchased for $500 or more Poshmark will authenticate stones and 14k gold.
