A Fabergé Moonstone and Diamond-Set Pendant An oval pendant centred by a delicate, egg-shaped moonstone polished en cabochon, the gem suspended freely within a surrounding halo incrusted with rose-cut diamonds. The subtle luminosity of the moonstone contrasts beautifully with the glittering, silver-mounted diamonds, creating a soft, ethereal radiance typical of Fabergé’s refined jewellery work from the St Petersburg workshops.
