常见问题
Is 10K gold real gold?
Yes. 10K gold is real gold — it contains 41.7% pure gold (417 parts per thousand), with the remaining 58.3% being alloy metals such as copper, silver, and zinc. In the United States it is the legal minimum gold content that can be marketed and sold as gold jewelry. While lower in gold content than 14K or 18K, it is genuine gold, not plated or filled.

417 is the hallmark for 10K gold. It means 417 parts per thousand — 41.7% — of the alloy is pure gold. You will see 417, 10K, or 10KT stamped on US-made gold rings, chains, and earrings.
What is the difference between 10K and 14K gold?
10K has 41.7% gold vs 58.5% in 14K. 10K is harder, more durable, and significantly cheaper — typically 30–40% less expensive for the same piece. 14K has a warmer, richer yellow colour and is less prone to tarnishing over time.

10K gold is very durable for everyday wear — it is the hardest common gold alloy and highly scratch-resistant. The trade-offs are a paler yellow colour and higher potential for skin reactions due to its higher base-metal content.
