Stones & Materials

Brazil, first

Nearly every stone in this collection begins in the same place. Brazil produces more amethyst and more citrine than any country on earth — violet quartz from the great basalt geodes of the south, golden and green quartz from the mineral belts of Minas Gerais. Stone by stone, this is a Brazilian collection.

Yurua begins with the stone itself: its colour, its cut, the light it holds and the feeling it brings to a piece. Natural variation is part of the character of gemstone jewellery. No two stones need to look perfectly identical to feel like they belong together.

Amethyst

The violet one. Amethyst forms inside hollow volcanic rock over an unhurried stretch of geological time, and Brazil's southern geodes are among the richest sources of it anywhere. In crystal traditions it has long been associated with calm, clarity and intuition — a stone often chosen as a reminder to slow down.

The current collection includes amethyst stud earrings and an amethyst pendant necklace.

Citrine

Citrine is the golden one. It is the same mineral as amethyst — quartz — separated only by heat and the iron held inside it. Much of the world's citrine begins its life violet and turns honey-gold, either slowly in the earth or through careful heat treatment by a cutter. Yurua is plain about that: where citrine has been heated to reach its colour, we treat it as part of the stone's material story, not something to hide.

It is a stone with transformation written into its chemistry, which is perhaps why, in crystal traditions, it has long been associated with optimism, confidence and new beginnings.

Yurua's citrine pendant uses a clean rectangular cut that puts the colour at the centre of the piece.

Green amethyst

Green amethyst is the green one, and the least known. Its proper name is prasiolite. Quartz again — same family, a third colour. Natural prasiolite is uncommon; most of what reaches the world begins as Brazilian amethyst and is heat-treated to green. That is the route most commercial green amethyst takes, and it is the tradition of colour Yurua draws from when this stone appears in the collection.

Settings and metals

Yurua works in two metals, and only two.

18 karat gold. Seventy-five percent pure gold, hallmarked 750. It is the standard used across most of Europe for fine jewellery, and it is what we use for the citrine pendant, the amethyst pendant and the green-and-violet drop earrings. Solid gold, not plated and not filled — which means the colour is the metal itself and cannot wear away from the surface over time.

Sterling silver. 92.5 percent pure silver, hallmarked 925, used for the amethyst stud earrings. Sterling develops a patina with wear and air; a soft polishing cloth returns it whenever you would like it brighter.

We name the metal on every product page. Where a piece is gold, it is 18 karat gold throughout — setting, chain and findings.

Meaning, not medicine

Yurua draws on the symbolic and cultural associations people have carried with gemstones over a very long time. These associations are offered as inspiration and personal ritual. They are not medical claims, and no piece of jewellery diagnoses, treats or cures any condition.
