Estate Of Major Riddle aka Mr. Las Vegas Diamond, Ruby and Emerald 18k Yellow Gold 35" Necklace

Mid-century (1950s) custom designer “MJI” necklace in 18K yellow gold, featuring a substantial long chain and a sculptural, openwork pendant with diamond accents and cabochon ruby and emerald pops of color. The look reads bold yet refined—ideal for high-jewelry showcases, estate/vintage edits, and clients seeking an elevated statement piece that transitions from cocktail dressing to evening wear. Strong merchandising value for “Mid Century,” “High Jewelry,” and “Color + Diamond” storytelling, with immediate case impact from the pendant’s dimensional design and saturated gemstone contrast.
