For a closely related figure of Sitatapatra, see M. Henss, "Early Tibetan Sculpture," in P. Pal (ed.), On the Path to Void, Buddhist Art of the Tibetan Realm, 1996, cat. no. 18, p. 116, likely attributable to the same workshop. This rare type, with the unusual tiered crown and elaborate jewelry, also relates to the image of an eight-armed goddess in a 13th century thanka of 'Four deities' in the Fournier collection, see G. Bguin, Art sotrique de l'Himlaya, 1990, fig. 3, p. 22. The present example is exceptional in quality of workmanship and extensive use of inlay.
