David Yurman Ring

David Yurman 18mm Albion Black Onyx Diamond David Yurman 18mm Albion Pave Black Diamond Ring Sterling Silver Original Box Included Absolutely Beautiful! Minimal signs of wear and tear on edges. This was ordered on David Yurman website. I ordered in size 9 to fit my middle finger (my ring finger is size 7). I sold this ring on Poshmark but they returned it saying the correct size of the ring is 7.5. So, I reposted as that size as to not lose a sale again on this ring. I am unclear about why there is such a huge difference between what I ordered and what Poshmarks determination of the size was. And, I have since ordered other rings, in size 9, and they fit my middle finger. So-this is just a heads up on the size which I am still convinced is a size 9.
