Above is a good profile pic of Queen Victoria !! If yours was supposed to be the Queen,, they were not very accurate !! My personal opinion is that the porcelain insert is only in the style of Sevres and not made by Sevres !! There is a huge difference in quality between the pair on 1stdibs and yours !! And the pair on 1stdibs was attributed to a known maker !! But that is only my opinion !! I believe Christi`s has an appraisal that is free as well as Skinner and possibly other major auction houses !! Send pics to them and get a professional opinion !! I have studied furniture for 40 years both American and English items but several opinions are better than one !! And guessing from pics is sketchy at best !!
