The inspiration of the «Maori» collection was the culture of the indigenous people of New Zealand. The collection consists of pendants, each of which represents a traditional symbol of the Maori people and carries a sacred meaning.

The new collection "Suprima" was inspired by the direction of avant-garde art of the beginning of the 20th century - Suprematism. A distinctive feature of this direction is the use of geometric abstractions. Due to the hardness of our alloys, PalladinGold™ was able to reproduce pronounced geometric shapes with sharp edges that do not fade with time, like in jewellery made of “soft” alloys.

Decorative crosses from our jewellery studio is not quite ordinary. They are bilateral, which means that one pendant can be combined with even more looks.
Decorative Crosses

The inspiration of the collection of wedding rings "Möbius Strip" was the three-dimensional figure, which has only one side and one border. The mysterious geometrical figure seems to be talking about the interconnectedness and infinity of everything in our world. In the same way, a man and a woman bind their destinies to follow along the same path.
