All artwork manufactured and sold by ECOLSON as a “gold masterpiece” is manufactured in certified American gold with a purity of minimum 14 karat.

When gold element (Au) is discovered in nature, it is found pure and undiluted. Pure gold is 24 karat. It is very malleable and makes it inappropriate for jewelry due to its softness. Our fine gold is diluted via man-made process known as “alloying” to make it harder and more resilient to scratches. The 14-karat gold is composed of 58.3% pure gold and 41.7% alloy. This is the most famous option for engagement rings and other wearable jewelry in the United States, the UK and the other Western countries. The 14-karat metal composition offers the best combination of a rich color, more durability and resistance to wear and tears. 

All Artwork is in solid gold. It has no empty core or surface plating. The exact purity and weight of each masterpiece is specified on its certificate of Authenticity.

The karat system helps define the purity or fineness of metals used in the manufacturing of jewelry and U.S. federal law requires that all jewelry be stamped with an accompanying hallmark clearly denoting this purity.
