When investing in precious jewelry, it’s important to understand the differences between the choices of high carat golds.
Understanding Gold Purity
Gold is measured and valued based on its purity, ie, the components of its 24 parts. At the highest end, having all 24 parts gold, 24k gold is 99.99% pure. The lower the karat number, 22k, 18k, 14k, the more the gold is alloyed with other metals like copper, silver, and zinc to strengthen its durability and lower its cost.
- 22K Gold: Contains 91.67% pure gold and 8.33% other metals.
- 18K Gold: Contains 75% pure gold and 25% other metals.
The Beauty of 22K Gold
22K gold has a rich yellow color and is used for higher end, luxury jewelry. Here are its benefits:
- Purity and Value: At 91.67% purity, 22K gold is more valuable than 18k gold. As gold prices continue to rise steadily, its intrinsic value will always be greater than 18k gold.
- A Golden Glow: The high purity of 22K gold gives it a more vibrant and luxurious appearance – a feature that those with discerning taste find appealing and hard to resist.
- Hypoallergenic: The high gold content of 22K gold makes it far less likely to cause allergic reactions which is important for those with sensitive skin.
Before purchasing 22k gold jewelry, however, it is important to be aware that it is a softer and more delicate metal than 18k gold. The higher gold content means that 22K gold is more malleable and prone to scratches and dents. It should only be purchased by someone that knows how to properly care for it.
18k Gold – a Durable Choice
18K gold strikes a good balance between purity and durability, making it a good choice for pieces that are worn daily and kept for heirlooms. Made from 25% alloyed metals, 18K gold is stronger and more durable than 22K gold. It’s less prone to scratches and dents and doesn’t require the same level of gentle care and storage. Moreover, 18k gold allows for more design flexibility. The added strength of the metal allows jewelers to create more intricate and complex designs, including those with prong settings and detailed patterns. This makes 18K gold a popular choice for engagement rings that are worn daily and may be knocked against hard surfaces.
Remember though, that since 18k gold contains lower purity, its intrinsic value is lower in comparison to 22k gold, but still holds substantial value. Also, the added metals make 18k gold less hypoallergenic than 22k gold and increases the likelihood of allergic reactions.
When making your decision, it is important to determine what is most important for you, luxurious exclusivity along with long-term appreciation in value or practical, durable elegance that allows for more flexibility in design and wear.
