Cashmere, vicuña and wild silk: the ultimate guide to the world's noblest fibres

Softness can stop you in your tracks.

Imagine a small market in Leh at dawn, a trader unfolding a Pashmina shawl, steam from a chai stall hanging in the cold. The shawl is almost translucent, the weave catching the light like smoke. Or picture a Peruvian artisan in the high puna, sunlight on the sandy coat of a vicuña grazing near a centuries-old stone enclosure. In Assam, a woman hands you a piece of raw wild silk, its colour uneven and alive, the scent of the river still in the threads. These are places where fibre means livelihood, ritual and identity.

Warmth and rarity

Cashmere, vicuña and wild silk share one trait: scarcity. Cashmere comes from the undercoat of Capra hircus in the high plateaus of Mongolia, China and parts of the Himalaya. Vicuña (Vicugna vicugna) is native to the Andean highlands of Peru, Bolivia and Argentina and yields very limited quantities per animal. Wild silks (for example tussar, eri, and 'ahimsa' silk) are produced by non-mulberry silkworms, often in India and parts of Southeast Asia, and cannot be farmed at the scale of Bombyx mori silk without changing their character.

The numbers explain the prices. A kilogram of raw cashmere fleece can cost several hundred euros at auction, depending on micron and yield. Vicuña fibre is rarer, with only a few hundred tonnes harvested globally each year, making finished vicuña garments the most expensive in the wardrobe of high luxury houses. Wild silk, less uniform and often shorter in fibre length, commands premium prices when hand-collected and ethically processed, because of labor intensity and low volumes.

Luxury houses, small cooperatives and specialist mills play different roles. Brands such as Loro Piana and a handful of ateliers in Italy and Peru transform vicuña into scarves and coats that are both technical and ceremonial. Meanwhile independent weavers in Assam keep wild silk techniques alive, producing textiles that luxury designers occasionally reintroduce to Western runways.

Origins and stories

The story of cashmere intersects with empire and fashion. Kashmiri shawls were objets de désir in 18th and 19th century Europe, inspiring pattern-makers in Paisley, Scotland. The name 'Pashmina' originally referred to the fine wool of the Changthangi goat in Ladakh and Kashmir, hand-spun and woven by artisans whose families kept the craft for generations.

Vicuña faced near extinction in the mid 20th century because of overhunting. International protections and community management led to a remarkable recovery. Today, vicuña fibre is often shorn or harvested during live-capture events organized by local communities, and many Peruvian cooperatives auction fibre in Lima to fund conservation and social projects.

Wild silk traditions are equally rooted in place. Tussar from central India carries natural golden hues, eri (muga) silk from Assam is known for durability and a rustic aesthetic, and 'peace silk' (ahimsa) allows the moth to emerge, offering an ethical alternative appreciated by some designers and consumers. These silks retain irregularities that some call flaws, but which give garments character and depth.

Care and buying

Caring for these materials preserves their value. For cashmere, gentle hand wash in cool water with a mild detergent, or professional dry cleaning, will maintain loft and handle. Fold, do not hang, and store with cedar if moths are a concern. For vicuña, always follow label recommendations; many pieces require professional care and careful airing after wear. Wild silk benefits from gentle washing and should be dried flat to keep shape and sheen.

When buying, ask for provenance. A micron count tells you fibre fineness (lower is finer). Look for traceability: cooperative names, auction houses, and certification schemes are reassuring. Be wary of blended pieces marketed as 'cashmere' with a tiny percentage of true fibre. Touch matters. A reputable dealer will let you feel the hand, examine the weave and explain origin.

Finally, consider longevity over impulse. These fibres repay care. A well-made Pashmina, a vicuña scarf, or a wild silk garment can become heirlooms, carrying stories of place, technique and the people who made them.
