This is a lovely old cobalt blue gilded vase Handpainted with a medallion floral centrepiece - it has turquoise enamel highlights around the golden cartouche -  perhaps enamel? Which I think is a ‘jewelled’ early piece - possibly from the Osmaston Road factory - it is lovely size measuring approximately 17.5cm tall - I am not an expert so please look carefully - I think it is very early Royal Crown Derby - it has been dated/signed in handwritten green letters and numbers - it is also incised with the same number of 5778 - I think it’s really old but please make contact if you have any info as I would really like to understand where this vase was made - nice collectible item
