What does 835 mean on jewelry?
Short answer
835: 835 parts per thousand silver.
A mark is a statement, not proof: it can be forged or struck on a plated piece. An assay confirms it (touchstone and acids, or X-ray fluorescence).

What is 835 worth by weight?
Every gram of a piece stamped 835 holds 0.835 g of fine silver, if the stamp is accurate. Multiply that by the spot price of silver to get the melt value. It is the floor, what the metal is worth if melted, not what a buyer will pay and not an appraisal.
Example, clearly not live: 10 g at the example price of $51.87 per troy ounce (snapshot of 2026-11-10) is $13.93. The working: 10 g → 835 / 1000 → 10 g × 0.835 → 51.871 USD/ozt ÷ 31.1034768 g/ozt → 8.35 g × 1.6677 USD/g.
