A practical field guide

How to identify precious metals after a fire.

Do not worry if an item no longer looks like jewelry. Heat may change its shape and surface while valuable metal remains.

Look before you test

Four safe clues you can check at home.

01

Find a hallmark

Look inside rings, on clasps, or on the back of an item. Use a phone camera and zoom instead of scraping the surface.

  • Gold: 10K, 14K, 18K, 22K, 417, 585, 750 or 916
  • Silver: Sterling, 925, 900 or 800
  • Platinum: PT, PLAT, 900Pt or 950Pt
  • Palladium: PD, PALL, 500 or 950
02

Try a gentle magnet check

Gold, silver, platinum, and palladium are not strongly magnetic. A strong pull can suggest steel or another base metal—but clasps, springs, and mixed parts may react, so this is only a clue.

03

Notice weight and color

Precious metals often feel heavy for their size. Gold may remain yellow beneath soot; silver may turn gray or black; platinum and palladium may look gray-white. Color alone cannot prove metal content.

04

Keep fused pieces together

Melted jewelry may become beads, irregular lumps, or several items fused into one mass. Do not break it apart. Stones, clasps, and base-metal pieces can be sorted during professional evaluation.

Protect the material

Do not clean, grind, melt, or acid-test it.

Cleaning can remove small metal particles and identifying marks. Home acid tests and remelting can cause burns, fumes, contamination, and lost material. Place each group of items in a separate sealed bag or rigid container instead.

Identification is preliminary.

Hallmarks, appearance, and magnet response can help sort material, but only professional testing and weighing can determine metal content and purchase value.
