Faberge Palais Tsarskoye Selo Turquoise Crossover Ring. 2108. The Faberge Imperial Collection is inspired by the jewelled splendour of the Imperial Romanov court, and evokes the rhythms of the Russian seasons, whether literal or metaphorical. Palais Tsarskoye Selo Turquoise Cross-Over Ring features turquoise guilloche enamel and white diamonds, set in 18ct yellow gold. In keeping with its fondness for delight, surprise and discovery, Faberge has concealed a ruby on the inside of the ring. This ring comes beautifully packaged in a unique Faberge presentation box with certificate of authenticity.
