In the style and workmanship, of the great designer Marina B. (but not signed), this striking necklace centers an important fine natural emerald weighs approximately 25+ cts. This natural large emerald is probably Colombian and displays a pleasing bright green color. This fine heart shaped emerald is surrounded by fine matching fancy cut white, collection quality, diamonds which are all colorless to near colorless (F/G) and very very slightly included (VVS), in clarity. The five strands of Akoya pearls measure 4.0 to 5.0 mm. The well matched white pearls are lustrous and free of surface blemishes. The two decorative diamond and gold elements set within the strands of pearls are set with fancy cut tapered baguette cut diamonds and round brilliant cut diamonds. The total diamond weight of this necklace is approximately 6+ cts. This choker necklace is well made probably by an important house, it bears a maker’s mark which we are unfamiliar with. This important necklace fits at the collar and is expandable for on/off ease and will fit most necklines. Circa 1965.
