No sé si se llegó a debatir en su momento. Pero hace tiempo, en 2011, Christie's subastó dos de las esmeraldas de Ena, presentadas como "las esmeraldas de la Emperatriz", por su vínculo con Eugenia de Montijo.

Parece ser que provienen del broche y la sortija, no del collar. ¿Cómo de seguro es que el collar fue comprado por el Sha? ¿No se podrían haber confundido con las también desaparecidas esmeraldas de la diadema Cartier? Se ajustan mucho más al tamaño de las esmeraldas del collar de Farah Diba...

One of the most beautiful women of her time, Eugénie de Montijo, Countess of Teba, was born in Spain in 1826 and educated in Paris, where her elegance and charisma seduced Louis-Napoléon Bonaparte, who ascended the throne as Emperor Napoleon III in 1852.

Made an Empress by her marriage the following year, Eugénie greatly influenced French fashion. She famously loved jewellery and, green being her favourite colour, adored emeralds. Among her preferred jewels was a personal tiara with nine emeralds. Upon her death in 1920, she bequeathed nine emeralds, most probably un-mounted from that tiara to her goddaughter, the future Queen Victoria Eugenie of Spain, who wore them many times, mounted in a necklace, then re-mounted as a parure.

As the Queen of Spain herself had to leave in exile, she sold the jewels at auction in Bern in 1961. Subsequently the brooch and the ring were acquired by the mother of the current owner who had the stones remounted by Swiss jeweller Meister as a pendant and a ring.

The two rectangular-cut emeralds weighing 17.97 and 15.99 carats, with diamond set ring and pendant fitting by Meister, are now offered for sale with an estimate of SFr.200,000-300,000; illustrated above left). The sale of these gems is a unique opportunity to acquire historic stones.
