The rock this stone grew in is older than the ocean between Brazil and Africa.
That is not a figure of speech. Around 135 million years ago a continent tore in half, lava came up through the crack, and the Atlantic filled the gap it left behind. We make jewellery out of what grew, very slowly, inside that lava.
First, in order.
Brazil and Namibia used to be the same piece of ground. When they came apart, an enormous flood of basalt covered both sides of the tear. Half of it is still in southern Brazil. The other half is in the Namibian desert, and the South Atlantic runs between them.
That basalt is around 135 million years old. It cooled quickly and left cavities behind — hollow pockets, sealed inside the rock.
Then, for a very long time, nothing happened.
Eventually groundwater carrying dissolved silica found its way into those pockets and began lining them with crystal, without hurry, one layer at a time. That is where amethyst comes from. More of it comes out of Brazilian ground than out of any other country on earth.
That is not a marketing claim. It is simply where these stones come from.
It was not forged in fire.
This is the part almost everyone gets wrong, ourselves included until we went and read the geology. The amethyst was not born in the heat. The heat came first, and was gone.
The crystals grew afterwards, out of warm water. Studies of the classic Brazilian geodes put the temperature of that water between 40 and 80 degrees. Bath temperature. About the heat of a cup of tea you have left too long.
Everything violet about the stone is the result of patience at low heat over an unreasonable stretch of time. We find that considerably more impressive than fire, and it has the advantage of being true.
What a stone is actually for.
People have worn stones for as long as there have been people. Amethyst for calm, citrine for beginnings — for centuries, across cultures that never met. They were not being foolish.
Here is what is actually happening, and it is not complicated. Almost everything you own is designed to change. Your phone degrades on a schedule. Your clothes are made to be replaced next season. Very little that you can buy is genuinely indifferent to you.
A stone is. It will not improve. It will not respond. It will not fade, wear out, update, or ask anything of you. It has already outlasted everything that ever tried to outlast it, and it will outlast you without noticing.
That is how intention has always been made to stick — not by thinking it, by wearing it. A decision, a person, a year you got through: you give it to an object that does not change, and it carries it for as long as you keep wearing it.
Which is why a Yurua piece is worth more to you in year five than on the day it arrives. It is also the honest argument for buying one good thing instead of six forgettable ones, and we would rather make that argument than a louder one.
A river gave us the name.
The Juruá runs for more than three thousand kilometres through the western Amazon before it meets the Solimões. It is slow, patient water. It carries what it gathers a very long way, and it is in no hurry to arrive.
Yurua is named for that river. Not as ornament, but because the river had already described what we wanted the jewellery to do: hold something quietly, and carry it.
The ground is slower than the river. The stone is older than both. You are the fastest thing in this story by a comic margin — which is, more or less, the point.
Two metals, and only two.
- 18 karat gold
- Seventy-five percent pure gold, hallmarked 750 — the European standard for fine jewellery. Solid: not plated, not filled, not vermeil. Where a piece is gold, it is 18 karat throughout — setting, chain and findings.
- Sterling silver
- 92.5 percent pure silver, hallmarked 925. It develops a patina with wear and air; a soft dry cloth returns it whenever you would like it brighter.
- Stones
- Brazilian amethyst, citrine and green amethyst (prasiolite). Where a stone is commonly heat-treated — citrine and prasiolite usually are — we say so on the product page rather than leaving you to find out.
- Releases
- Small collections, small releases, sold directly from Switzerland. Tracked delivery.
I carried a stone in my pocket as a child. I could not have told you why. It was simply there — the same on a good day as on a bad one — and there is a steadiness in that which I never grew out of.
Yurua is the grown-up version of that pocket. Something worth keeping, made properly, from stones that actually come from somewhere. The steadiness was always mine. The stone only had to hold still for it.
Brazilian stone. Solid metal. Worn every day.
A small collection of pieces in 18 karat gold and sterling silver, made to be worn close and kept a long time.
