Fine Victorian Diamond Heart Locket

ca. 1880, silver top, 15k yellow gold back, the heart-shaped locket pave-set with old mine-cut diamonds, the reverse set with a conforming colorless rock crystal cabochon hinged locket back, suspended from a "strawberry leaf" bail set with old mine- and rose-cut diamonds, with an approximate total diamond weight of 6.30 carats, suspended from a later ca. 1915 platinum fancy "paper clip" link chain set with nine round brilliant-cut diamonds weighing approximately 0.70 carats in total.
locket (with bail) l. 1-1/2", w. 1", chain l. 22-3/4", total weight 16.7 grams

In overall quite good condition. All diamonds appear to be original. Locket hinge good and the cover fits securely (though slightly worn with age). The bail was evidently originally "split" to allow it to be attached to a larger chain, but has since been professionally gold-soldered closed. No marks. The chain is of a later date as noted; in good condition. Spring rings 14K white gold and so marked.
