833
20-carat gold · 83.3% pure
833 means 20-carat gold: 83.3% pure, an uncommon grade between 18-carat and 22-carat. It's recognised in India (under IS 1417) and historically in Belgium, struck as “833”. A high-purity gold with a warm colour, it's a regional standard you'll meet far less often than 18K or 22K.

Why 83.3%?
20-carat (833) is one of the in-between gold grades that some standards recognise — notably India's — sitting above 18K but below the prized 22K of the South-Asian and Gulf markets.
At 83.3% pure it behaves like the other high-carat golds: soft, warm-toned and valued largely for its gold content rather than its hardness.

What people actually ask
Is 833 the same as 20K?
Yes. 833 is the millesimal (83.3% pure); 20K is the carat (20 parts gold in 24).
Is 833 real gold?
Yes — high-purity real gold, 83.3%. It's recognised in India and was used historically in Belgium.
Why is 20-carat gold uncommon?
Most markets jump from 18K to 22K, so 20K sits in a gap only a few standards (India's among them) formally recognise.
What is 20K gold worth?
83.3% of its weight is pure gold, so its melt value is high — over four-fifths of the same weight in pure gold.
