What Does 750 Mean on Gold Jewellery?
When you come across the number “750” stamped on gold jewellery, it indicates the purity of the gold used in the piece. Specifically, this mark means that the alloy consists of 75% gold and 25% other metals, resulting in 18-karat gold.
Understanding Gold Purity Marks
Gold purity is measured in karats (K) and parts per thousand (‰). Here’s a quick breakdown:
- 24K Gold: 100% pure gold
- 18K Gold: 75% gold (750)
- 14K Gold: 58.3% gold
- 10K Gold: 41.7% gold
The higher the karat number, the greater the amount of pure gold in the jewellery.
Benefits of 18K Gold
- Durability: The addition of other metals, like copper or silver, gives 18K gold greater strength and durability compared to pure gold, which is relatively soft.
- Appearance: 18K gold has a rich yellow hue and a luxurious appearance, making it a popular choice for high-end jewellery items.
- Hypoallergenic Options: Many 18K gold items are less likely to cause allergic reactions compared to lower karat golds, depending on the alloy metals used.
Summary
In summary, the “750” mark on gold jewellery signifies that the item is composed of 75% gold, categorizing it as 18-karat gold. This purity level offers a great blend of richness in appearance and durability, making it a favored choice among consumers and jewellers alike.
