What Determines Value
What makes inherited jewelry valuable
Not all inherited jewelry is valuable — but some of it is worth far more than people expect. The difference between costume and a piece worth thousands often comes down to a few specific factors that a specialist can identify from photographs.
Precious metal content
Gold (10K, 14K, 18K, 22K), platinum, and sterling silver have intrinsic melt value that establishes a floor price. Look for karat stamps (10K, 14K, 18K, 750, 585, 925). This floor value exists regardless of style, age, or condition.
Gemstones
Diamonds, rubies, sapphires, and emeralds drive value significantly. Size, quality, and setting all matter. But many inherited stones are smaller or lower quality than assumed — and many assumed diamonds turn out to be cubic zirconia or glass.
Period and style
Victorian (1837–1901), Edwardian (1901–1915), Art Deco (1920–1935), and Retro (1935–1950) pieces have dedicated collector markets. Period attribution adds premium above metal and stone value.
Designer and maker
Signed pieces by recognized jewelry houses command premiums. Tiffany, Cartier, Van Cleef & Arpels, David Webb, and others carry brand value. But lesser-known makers from the right period can also be valuable.
Watches
Vintage watches are their own market entirely. Rolex, Patek Philippe, Omega, and other Swiss manufacturers have exploding collector demand. Even non-running inherited watches can be worth thousands.
Costume jewelry
The surprise category. Signed vintage costume jewelry from Miriam Haskell, Eisenberg, Trifari, Schiaparelli, and others can sell for hundreds to thousands. Not all costume is worthless.
