தொடர்ந்து கேட்கப்படும் கேள்விகள்
Is 9K gold real gold?
Yes. 9K gold is real gold — it contains 37.5% pure gold (375 parts per thousand), with the remaining 62.5% being alloy metals such as copper, silver, and zinc. It is the minimum gold content legally sold as gold in the UK, Ireland, and Australia. While lower in gold content than 14K or 18K, it is genuine gold.
What is the 375 hallmark on jewelry?
375 is the hallmark for 9K gold. It means 375 parts per thousand (37.5%) of the alloy is pure gold. In the UK, Ireland, and Australia, you will commonly find 375 stamped on gold rings, chains, and earrings. It is equivalent to the 9ct or 9K designation.
Is 9K gold good for everyday jewelry?
9K gold is very durable for everyday wear because it contains more hardening alloy metals than 14K or 18K. It is scratch-resistant and holds its shape well under friction. The trade-off is a paler yellow colour and higher potential for skin reactions if you are sensitive to copper or silver alloys.
What is the difference between 9K and 14K gold?
9K has 37.5% gold vs 58.5% in 14K. 9K is harder, more affordable, and the standard in UK and Australia. 14K is more common in the US and has a richer yellow colour. 9K is more prone to tarnishing over time due to higher base metal content.
