Karen Hallam's oval ring is a minimal, modern and sophisticated design that flatters and makes the hands longer, as it does not cut the line of the finger.
You can wear it on the ring finger, but it also looks beautiful on the index finger.
You will get a lot out of it, as Her majesty Queen Leticia of Spain does, wearing it day and night, from jeans to gala styles.
FInd your size by placing your ring on a rule to find your diameter, and check the correspondeing size on the ring size chart provided at product page.
