How Estate Jewelry Is Valued

Jewelry is valued in a set order: the metal and its purity, the stones and their quality, the maker and the design, then the condition. Each step uses a test or a tool. Nothing is judged by eye alone.

One factor rarely tells the story. A plain gold band and an Edwardian diamond ring weigh about the same in gold. The second is worth far more because of its stones, its maker, and its design. That is why each piece is looked at on its own and never priced by the pound.

Metal and purity

Gold, platinum, and silver are tested for purity with markings, acid, or an electronic tester. Stamped karat marks wear down and are sometimes wrong, so the test settles it. Weight counts once purity is confirmed.

Stones

Size is the easiest thing to see and the least telling. Cut, clarity, color, and whether a stone is natural or lab grown matter more. A loupe or a jeweler’s microscope picks up chips, inclusions, and treatments the naked eye misses.

Maker and design

A hallmark, a signature, or a period style adds as much as the gold and stones. Here is what raises a piece above its materials.

• A signature from a known house, such as Tiffany, Cartier, or Van Cleef
• Design from a collected period, like Art Deco or mid-century
• The original box, papers, or receipt kept with the piece
• Hand-finished settings and fine construction details

Condition

Wear, damage, old repairs, and missing parts all lower the number. A brooch in original condition finds a buyer more easily than one that was reworked, even when the materials match.

Why we look through the whole estate

Estate jewelry rarely stays in the jewelry box. It turns up in dresser drawers, sewing kits, coat pockets, a coffee can on the closet shelf, and a safe deposit box nobody has opened in years. We walk every room for that reason, so a pearl strand in a handbag gets the same look as the ring on the dresser.
