Amongst the jadeite varieties, a pair of jadeite cabochon ear studs will be displayed that contain stones which are internally luminous and clear, radiating a remarkable depth of colour, a bright and intense emerald green typical of Burmese jadeite. Also a superb jadeite bead necklace carved from a single piece of gem-quality rough will be on auction. The necklace consists of 73 perfect beads – each matching in colour and shape. The high translucency of each intensely-saturated vivid green bead displays a combination that is both valuable and rare.

The sale will also present coloured gems, including emeralds, very worthy amongst which is a pair of emerald and diamond ear pendants set with Colombian emeralds weighing 9.12 and 8.84 carats, carrying a lineage of the Romanov dynasty.
