21K means the piece is 21 parts gold out of 24, or 87.5% pure gold, alloyed with 12.5% other metals for strength. It's a common standard in Middle Eastern gold markets, between 22K and 18K in purity.
No — 22K is 91.7% pure, higher than 21K's 87.5%, so 22K is worth slightly more per gram. 21K is sometimes preferred because its extra alloy content makes it a bit more durable for everyday jewelry.
It depends on the piece's weight — multiply its weight in grams by today's 21K price per gram above, or use the Gold Calculator to enter the exact weight for a precise figure.
