About KaratGuide
A free, visual reference for anyone who has ever wondered what "14K gold" actually means.
What is KaratGuide?
KaratGuide is a free educational website that explains gold purity, karat grades, and precious-metal alloys in plain language — with visual tools to make the concepts stick.
Whether you're buying your first piece of gold jewellery, comparing white gold versus platinum, or just curious about what the stamp on the inside of a ring means, KaratGuide is built to give you a clear, honest answer without the jargon.
What we cover
Karat grades
24K, 18K, 14K, 10K — what the numbers mean and how purity is measured.
White gold
Alloys, rhodium plating, durability, and how it compares to platinum.
Rose gold
Copper ratios, why the colour varies between karats, and care tips.
Green gold
Electrum, the natural silver-gold alloy, and its use in jewellery.
Silver
999, 958, 925, 800 — silver grades, hallmarks, and tarnish explained.
The droplet visualiser
Each guide includes an interactive droplet chart that shows the exact composition of a karat alloy — how many parts out of 24 are pure gold, and which metals make up the rest. You can drag the droplets, merge them, and see the proportions change in real time. It's designed to make an abstract number like "58.3% gold" feel tangible.
Available in 30+ languages
KaratGuide is fully translated into over 30 languages — from English, Norwegian, German, French, and Spanish to Japanese, Hindi, Arabic, and Urdu. Every page is written specifically for its language, not machine-translated, so the content reads naturally wherever you are in the world.
