Gold & Gold Jewelry
Explore the Gold Kings guide to gold, including karats, hallmarks, testing, gold values, jewelry, bullion, scams, and everything you should know before buying or selling gold.
A tooth mark cannot identify gold or its karat. Learn why the bite test is unreliable and why jewelry and coins need more appropriate authenticity checks.
Pure gold does not rust, but alloys, plating and other components can discolor. Learn what brown, red, green or black changes may mean before judging a piece.
Real gold can sometimes tarnish—but the gold itself usually is not the problem. Learn why 10K, 14K, and 18K gold can discolor, why 24K behaves differently, and when tarnish should make you consider professional gold testing.
Dark skin marks do not automatically mean fake gold. Explore how alloy metals, friction, cosmetics and moisture can leave residue from genuine jewelry.
A genuine gold alloy can leave green residue through reactions involving its other metals. Learn why skin color is not a reliable test of gold purity.
Counterfeit stamps, plated jewelry, fake bullion and convincing packaging can mislead buyers. Learn which claims need checking before a gold transaction.
Designer marks, gemstones, craftsmanship and provenance may justify an appraisal before selling for scrap. Learn how jewelry value differs from metal value.
An old gold watch can sometimes be worth considerably more than the gold inside it. Learn when brand, rarity, movement, originality and collector demand matter—and when gold content determines most of the value.
Learn how solid-gold, gold-filled and plated eyeglass frames differ, which markings to inspect and when antique or designer value may exceed the metal value.
Identify inherited jewelry before deciding what to keep or sell. Learn how testing, intact settings, documentation and clear offers support a careful evaluation.
