Art Deco Diamond & Lab-Grown Sapphire Necklace

Circa 1920. This elegant antique pendant is crafted in 14KT white gold and suspended from a platinum chain, showcasing the refined geometry that defined jewelry at the dawn of the Art Deco era. The pendant is accented with approximately 0.40 carats of round/single-cut/brilliant-cut diamonds with SI2-I1 clarity and H-I color. The striking 0.67-carat rose-cut diamond drop features VS1 clarity and G color. 

Rich blue period laboratory-grown sapphires totaling approximately 0.46 carats provide vivid contrast against the bright metals and diamonds. Far from being a modern replacement, laboratory-grown sapphires were first commercially produced in the late 19th century using the Verneuil process and became widely embraced during the early 20th century. Their exceptional color, durability, and affordability made them especially popular in Art Deco jewelry, where designers valued their ability to create bold geometric compositions with vibrant, consistent color. Today, these early synthetic sapphires are appreciated as authentic period materials that reflect the innovation and design aesthetic of their era.
