To create unique pieces, responsibly

Here are our engagements:

A sustainable creation with at its heart recycled silver

The entirity of our jewelry is made from recycled silver. We melt silver coming from the old jewels stocks that we recover (ols silver jewelry, our own pieces, or from old domestic electricals).We obviously do the sourcing of this melting locally in Indonesia near our workshop in Bali, and on the island of Java.

No mass-production

We try to not produce more than necessary : that’s why we maintain a low stock and we make our pieces according to your demands and orders, without waste.


Eco-responsability begins with the packaging !

No plastic ! We don’t want it and won’t resort to it, we respond to the problem of the carbon imprint with our packagings, by making them at our creations’ image : minimalists !

That’s why we only use bubble envelopes for an optimal protection, and your jewel is mailed in a Kaldera envelope in a velvet pouch. A package simple, beautiful yet efficient !


No gemstone

When hearing the term «gemstone», we think about all the controverses and scandals associated to it, completely against our beliefs. We prefer sticking to our designs, and use lava stone as our ornament for our collections, and stay true to who we are.

Its color and texture are the perfect blend to our silver designs, a minimalistic mix both raw and elegant.

A handmade fabrication

Our process avoids the use of molds, and we create the wholesome of our designs so that they could be done by hand. For us, a jewel has to be timeless, that lasts a lifetime, therefore each of our creations has to be unique and different : by doing them by hand, they become one of a kind.
