The brilliance that transcends time: 18k gold in jewelry
Share
Gold has always been a symbol of power, beauty, and eternity. But not all gold is created equal. In fine jewelry, 18-karat gold is considered the perfect balance of purity, durability, and brilliance: the choice of those who value authentic and conscious luxury.
At Luara, we work exclusively with 18k gold—and here's why.
What does “18 karat” really mean?
The karat (k) indicates the purity of gold : how much pure gold an alloy contains.
- 24k: 100% pure gold, too soft for everyday jewelry.
- 18k: 75% pure gold + 25% other metals (such as silver or copper).
- 14k: 58.3% pure gold, more resistant but less shiny.
18k gold achieves the ideal balance: it maintains the rich color and shine of pure gold, but with the durability necessary to accompany you every day.
Why we chose 18k gold at Luara
Each Luara piece is designed to last.
18k gold not only retains its color better over time, but also has a more luxurious weight and texture to the touch. It's the kind of jewelry that literally never fades.
In addition, working with high purity gold allows us to offer hypoallergenic jewelry, free of nickel and metals that irritate the skin.
18k Gold vs. Other Karat Weights: What You Need to Know
| Type of gold | Purity | Main features |
|---|---|---|
| 24k | 99.9% | Pure gold, very soft, deforms easily. Ideal for investment, not for daily use. |
| 18k | 75% | Intense color, deep shine, long-lasting and durable. Perfect for fine jewelry. |
| 14k | 58.3% | More economical, less warm color, less dense. |
| 9k | 37.5% | Very hardy, but paler in appearance and lower in value. |
Color also counts
18k gold can be found in different shades depending on the metals that accompany it:
- 18k yellow gold: classic, warm and eternal.
- 18k white gold: a blend of pure gold with palladium or nickel, giving it a modern, sophisticated tone.
- 18k rose gold: a feminine and romantic touch, thanks to the copper in its alloy.
At Luara, we celebrate everything, but yellow gold holds a special place: it is the universal language of timeless luxury.
Conscious luxury
Beyond aesthetics, choosing 18k gold is also a conscious decision.
Its durability means fewer replacements, less consumption, and parts that are truly inherited.
In a rapidly changing world, 18k gold jewelry represents the opposite: permanence, elegance, and purpose.
At Luara, each 18k gold piece of jewelry is created to last a lifetime. Because true luxury doesn't just shine: it lasts.
