Our Materials

We carefully select our diamonds, making sure they comply with our standards, with the purpose of being transparent to our customers.

All pieces of our collections are 18K gold with natural diamonds, precious gemstones or pearls.


What does 18K gold means?

Gold Karat is the measure of how much Gold is contained in a piece made with the metal. Karats measure the parts per 24, so that an item of 18 karat = ​ 18 ⁄ 24  = 75% , meaning that it is composed for the 75% in gold ( 24 karat gold is considered 100% gold). 18 parts of the piece are gold and the remainder parts are made up of other metals.
