Gorgeous ring but does not fit me anymore. Great pre-owned condition. I will update with a measurement of the inside circumference as this runs small although purchased as a size 6. very classy and sparkly. can be worn everyday. comes with valuation report and original dustbag. this will also go through Posh for authentication per policy. please note, David Yurman did say this ring can be resized. serious buyers only. will consider reasonable offers but priced appropriately as DY Jewelry holds original value and condition of ring. this piece is also discontinued but is a great match to th black diamond bracelet listed. details below- David Yurman Black Diamond Metro Band -from his metro collection -Sterling Silver -Marked with 925 and designer signature @ D.Y. -Total weight - approximately 9g - Total of 49 Round brilliant cut Black Diamonds! - carat weight 0.49 - Band Width - approximately 14.4m -size 6 - however will update with exact inner diameter in mm as it runs small and would say it is a 5.5. can be resized. any question ask!
