About the Item
This exceptional signed Gem Lok collar necklace is a striking example of 1980s American luxury design. Crafted in richly polished 18K yellow gold, the necklace features the brand’s signature tubogas construction, engineered to drape fluidly around the neckline with elegant weight and presence.
The front panel showcases a dramatic geometric mosaic of brown iridescent mother-of-pearl, accentuated with approximately 2.50 carats of round brilliant diamonds arranged in angular Art Deco–inspired patterns. The contrast of shimmering diamonds against the natural sheen of the mother-of-pearl creates a bold and sophisticated effect.
At a substantial 53.2 grams of 18K gold, the piece has a powerful yet refined feel. It is signed GEM LOK on the reverse, along with 18KP, confirming its gold purity. Gem Lok was widely known for its innovative gemstone-locking systems and sculptural forms, making their signed pieces highly collectible today.
A glamorous and wearable statement jewel—perfect for evening wear, collectors of modernist luxury, or anyone seeking a standout 18K tubogas design with exceptional craftsmanship.
