Here are a few reasons why you should opt for this type of jewelry:

Purity and durability

Gold is a metal whose main property is that it is naturally soft and malleable. Combining it with other metals to create an alloy increases its hardness, modifies its color and, above all, makes jewelry-making simpler and more resistant. Pure gold (24 carats or 24k) is rarely used to create jewelry; it is generally used for investment purposes. When gold has a lower carat value, such as 18 carats (18k) or 14 carats (14k), it is mixed with other metals to create a harder, more resistant alloy. Metals commonly used to strengthen gold include silver, zinc, copper and nickel.

24-carat gold is considered the purest form of gold, containing little or no other metals. However, due to its extremely soft nature, it is not commonly used for jewelry, as it is more susceptible to deformation or damage.

18-carat gold jewelry is an alloy composed of 75% of pure gold and 25% of other metals, such as silver or copper. This combination gives the jewelry greater strength and durability than 24-carat gold. Opting for 18-carat gold jewelry ensures that your pieces will stand the test of time. They will retain their beauty for years to come.

Radiance and shine

18-carat gold has a richer, more intense hue than other gold alloys. Its balanced composition allows jewels to shine brilliantly. You'll attract attention and add a touch of glamour to your appearance. Whether you opt for a bracelet, necklace or ring, you're sure to make a remarkable style statement.


As well as their aesthetic appeal, 18-carat gold jewelry is also a valuable investment. Gold is a precious metal whose value has risen through the ages, making it a solid form of investment. By choosing this jewelry, you combine beauty with timeless style that can be passed down from generation to generation.
