All measurements are approximate: Ring sits at 7 1/4 on a ring mandrel, 7mm x 2.5mm (sapphire), 2.5g. I was unable to measure the diamonds as they are too small. Item is in good condition. Includes some light scratches and finger oil marks. Will require some light cleaning/polishing. This item was tested using a JSP acid scratch test and tested as non-magnetic. The stones were tested using a Presidium Gem Tester. Items are not professionally tested and may be incorrect. All items are sold as-is. If you have any questions regarding this or any item in my closet, please feel free to ask. Thanks for stopping by!
