About Gold

Why is gold precious?

The total amount of gold produced from its discovery to the present day is approximately 3.8 Olympic-sized pools (50m). Being a finite resource is proof that gold has maintained its value across the ages.

Why use alloys?

Pure gold is extremely soft, stretching up to 3000m from just 1g. To ensure long-lasting wear, we mix silver, copper, and other metals to create beautiful and durable pieces.

Care Instructions

K5, K10, and K18 alloys may naturally tarnish over time. With proper care, they can maintain their brilliance for generations.

Daily Care

After wearing, gently wipe with a soft cloth. To maintain luster, store in a sealed bag or box. At agete, we propose care methods as "Loving Care" for long-term enjoyment of your jewelry.

Regular Cleaning
