Lovely solid 14 karat gold plumeria band. The ring is marked 14K, see photos for inside 14K mark and measurements. Important note: I purchased this ring as a size 5, however the same size ring can vary from ring to ring. The photo measurement shows that the INSIDE ring diameter is approximately 5/8". Before purchasing, I advise to measure a ring that fits you to compare. Please ask any questions in the comments section, thank you!
