Victorian Large Lapis Two-Tone Locket Back Brooch/Pendant

This big, bold, striking, and sensational late-Victorian/early-Edwardian era bauble (circa turn-of-the-20th-century, but evincing a decidedly modernist aesthetic), measures a quite conspicuous 1 1/4 inch in diameter and features a sizable round cabochon lapis lazuli imbued with a gorgeous glossy cobalt blue color. But the interest doesn't end there--the striking gemstone is encircled by alternating rings of rich 18K yellow gold and platinum (a rare example of the precious metal's earliest use), creating a very weighty and substantial frame of gleaming gold and white around the deep rich blue gemstone. Bonus: the reverse is furnished with an open-face glass-covered locket compartment (currently occupied with woven hair--commonly used in Victorian remembrance jewelry). A truly fabulous one-of-a-kind jewel, wearable as both a pendant and brooch. Hand fabricated. Chain measures 18 inches.
