Additional comments added on 9/27/23: The ring measures approximately 28mm long Additional comments added on 9/22/23: The Montreaux Tanzanite & diamond ring is in very good to excellent estate condition. There are a few very small abrasions and one tiny nick to the girdle of the center stone, all of which require 10x magnifications to see. The tanzanite displays good even blue-purple condition and the diamonds appear free from chips. The gold mounting and shank show minor wear consistent with use Unless stated in a laboratory report, gemstone and diamond color, clarity, and carat weight are approximate because stones are mounted at the time of evaluation
