Luxury silk: 5,000 years of textile excellence
Silk is the only natural fiber produced as a continuous filament, a unique property that gives it unmatched luster, strength and drape in the textile kingdom. Discovered in China around 3000 BC according to the legend of Empress Leizu, sericulture was for millennia the best-kept secret of the Middle Kingdom. The Silk Road, a 6,400-kilometer trade network linking Chang'an to Constantinople, testifies to the strategic value of this fiber: in the 1st century, one kilogram of raw silk was worth the equivalent of 12 ounces of gold in Rome. Today, global raw silk production reaches 180,000 tonnes per year (ISC 2025 data), with 83% from China and 15% from India. The global luxury silk market is valued at USD 16.8 billion in 2025, growing at 7.2% annually driven by demand for high-end textiles and biomedical applications.
Our ranking distinguishes two main silk categories. Domestic silks (Bombyx mori) represent 95% of global production: the mulberry silkworm produces a continuous filament up to 1,500 meters long, with a diameter of 10-13 microns and tensile strength of 4.5 g/denier. Wild silks (tussah, eri, muga) come from non-domesticated moths of the Antheraea and Samia genera: their filaments are shorter (300-700 m), thicker (25-35 microns) and feature naturally irregular texture highly prized in artisanal textiles. Muga silk, exclusive to Assam (India), is the only naturally golden silk, with durability 40% superior to standard mulberry.
This ranking evaluates 25 silk varieties across 8 laboratory-measured criteria: fiber fineness (diameter in microns, SEM measurement), tensile strength (g/denier, ISO 5079), luster (spectrophotometric measurement at 60 degrees, ASTM D523), drape coefficient (Cusick Drape Tester, BS 5058), dyeability (wash fastness ISO 105-C06), durability (Martindale cycles ISO 12947), weight per square meter (momme) and average price per kilogram on international markets (Shanghai, Bangalore and Como exchange data). Primary sources include the International Sericultural Commission, Textile Research Journal, FAO sericulture reports and our own analyses conducted with CIRAD.
Silk prices vary considerably by quality and origin. Mulberry silk grade 6A from Suzhou trades between 60 and 95 USD/kg, while Assam tussah silk is worth 35-55 USD/kg. Muga silk, extremely rare (annual production of only 150 tonnes), reaches 250-400 USD/kg. At the extreme, spider silk (Nephila), still experimental for textiles, exceeds 35,000 USD/kg due to harvesting difficulty. At Misciano, we exclusively use mulberry silks grade 5A and 6A for our scarves and linings, ensuring luster, drape and longevity worthy of haute couture.

Mulberry Charmeuse
Chine (Suzhou), Italie (Como)
La charmeuse de soie mulberry est le sommet de la hierarchie soyeuse. Son armure satin 4/1 cree une face brillante et un envers mat, avec un tombant fluide incomparable. Le filament Bombyx mori grade 6A de Suzhou offre un diametre de 10-11 microns, le plus fin de toutes les soies commerciales. Sa resistance a la traction atteint 4,8 g/denier, superieure au kevlar rapporte au poids. Les maisons Hermes, Chanel et Dior utilisent cette qualite pour leurs foulards signature. Le tissage a Como (Italie) reste la reference mondiale pour la finition et la teinture de la charmeuse de luxe, avec des techniques transmises depuis le XIVe siecle.
Muga (Antheraea assamensis)
Inde (Assam exclusivement)
La soie muga est la plus rare et la plus precieuse des soies sauvages. Produite exclusivement dans la vallee du Brahmapoutre en Assam (Inde), sa production annuelle ne depasse pas 150 tonnes. Sa couleur doree naturelle (sans teinture) est unique dans le regne textile et s intensifie avec chaque lavage. Sa resistance a la traction (5,2 g/denier) et sa durabilite (12 000 Martindale) surpassent toutes les autres soies naturelles. Protegee par une Indication Geographique (GI) indienne depuis 2007, la soie muga est traditionnellement reservee aux mekhela chadar royaux. Son prix reflète sa rarete extreme : un sari muga peut couter 2 000-5 000 USD.
Crêpe de Chine
Chine, Japon, Italie (Como)
Le crepe de Chine est un tissu de soie a armure toile utilisant des fils de trame fortement tordus (2 000-3 000 tours/m) qui conferent une surface legerement granuleuse et un drape fluide exceptionnel. La torsion alternee S/Z des fils de trame empeche le froissage et donne au tissu son elasticite naturelle. Le poids standard de 14 momme offre le meilleur equilibre entre legerte et opacite. Le crepe de Chine est le tissu favori des couturiers pour les robes qui doivent suivre le mouvement du corps sans coller a la peau.
Tussah (Antheraea mylitta)
Inde (Jharkhand), Chine (Liaoning)
La soie tussah provient du ver a soie sauvage Antheraea mylitta, qui se nourrit de feuilles de chene et de jujubier. Son filament, plus epais (25-30 microns) et plus court que le mulberry, presente une couleur beige-dore naturelle et une texture legerement irreguliere tres prisee dans le textile artisanal. Sa production est consideree comme cruelty-free (ahimsa silk) lorsque le papillon est laisse sortir du cocon avant le devidage. La soie tussah est 40 % plus resistante aux UV que la soie mulberry, ce qui en fait un choix pertinent pour l ameublement et les textiles exposes a la lumiere.
Organza de soie
Chine, Inde (Bangalore), Italie
L organza de soie est un tissu ultra-leger et transparent, tisse en armure toile avec des fils fortement tordus et empeses. Sa rigidite naturelle en fait le tissu de structure par excellence pour la haute couture : volumes, jupons, manches bouffantes et superpositions etherees. L organza de soie 6 momme est si leger qu un metre carre pese moins de 23 grammes. Contrairement a l organza polyester, la version soie offre un eclat chaud et une main plus souple. Les ateliers de haute couture parisiens (Chanel, Dior, Valentino) l utilisent pour leurs collections Printemps-Ete.
Eri (Samia ricini)
Inde (Assam, Meghalaya)
La soie eri (aussi appelee endi ou errandi) provient du ver Samia ricini, qui se nourrit de feuilles de ricin. C est la seule soie 100 % cruelty-free par nature : le cocon ouvert permet au papillon de sortir avant le filage. Sa fibre, la plus chaude de toutes les soies (conductivite thermique de 0,04 W/mK, comparable a la laine), est filee en discontinu comme le coton, donnant un fil plus epais et mat. L eri est la soie la plus durable (14 000 Martindale), lavable en machine et resistante au boulochage, ce qui en fait un candidat ideal pour la mode ethique et durable.
Habotai (Habutae)
Japon, Chine, Inde
L habotai (ou habutae) est un taffetas leger en soie pure, originaire du Japon ou il etait traditionnellement utilise pour les sous-vetements des kimonos. Son armure toile simple (1/1) avec des fils de faible torsion produit un tissu souple, lisse et legerement translucide. L habotai 8 momme est la reference pour les foulards de peinture sur soie, tandis que le 12-16 momme sert de doublure premium dans la haute couture. Sa surface lisse offre une excellente capacite de teinture, avec des couleurs particulierement vives et saturees. C est la soie la plus polyvalente du marche.
Dupioni (Shantung)
Inde (Karnataka), Chine, Thailande
Le dupioni (ou douppioni) est une soie tissee a partir de fils provenant de deux cocons fusionnes, produisant des irregularites (slubs) caracteristiques qui refletent la lumiere de facon unique. Cette texture nubby et son lustre brillant en font un favori pour les vetements de ceremonie et les robes de mariee. Le dupioni est plus rigide que la charmeuse, offrant une tenue structuree ideale pour les vestes et les jupes. Le Shantung est une variante plus fine du dupioni. La production indienne du Karnataka represente 60 % de l offre mondiale en dupioni de qualite.
Chiffon de soie
Chine, Italie, France
Le chiffon de soie est un voile ultra-leger tisse en armure toile avec des fils fortement tordus en alternance S et Z, creant une surface legerement sableuse au toucher et un drape aerien. A 6 momme, un metre carre pese moins de 23 grammes, le rendant presque invisible lorsqu il est superpose. Sa transparence et sa fluidite en font le tissu signature des robes de gala et des echarpes vaporeuses. Le chiffon de soie est l un des tissus les plus difficiles a coudre en raison de sa legerete et de son glissement, ce qui en fait un test d expertise pour les couturiers.
Soie brute (Raw Silk)
Chine, Inde, Bresil
La soie brute (raw silk ou soie ecrue) conserve une partie de son sericine, la gomme naturelle qui enrobe le filament de fibroine. Cette sericine (20-30 % du poids du cocon) donne au tissu sa rigidite caracteristique, sa texture croquante et sa resistance exceptionnelle. Non degrommee, la soie brute est plus durable que la soie traitee (12 000 Martindale), plus resistante aux UV et plus facile a entretenir. Son aspect mat et sa main ferme la distinguent des soies lustrees. Le Bresil est devenu un producteur emergent de soie brute de haute qualite, avec une production annuelle de 2 500 tonnes.
Ranking methodology
Our luxury silk ranking is based on a five-step evaluation protocol developed in collaboration with the International Sericultural Commission (ISC) and validated by the Textile Research Journal. Each silk variety was evaluated on a minimum of five samples from different production regions to ensure representativeness independent of sericultural terroir.
Data comes from six complementary sources: ISC (annual production and quality reports), Textile Research Journal (peer-reviewed articles), FAO (global sericulture statistics), Shanghai and Bangalore commodity exchanges (prices), ISO/TC 38 standards and our own testing in partnership with CIRAD and IFTH Ecully laboratory.
The scoring system assigns a 0-100 score per criterion, calibrated on the range of commercially available silks. A score of 95+ indicates world reference performance (top 3%), 75-94 very good performance, 50-74 standard performance and below 50 below-market-average quality.
Step 1: Fiber diameter measurement
Silk filament diameter is measured by scanning electron microscopy (SEM) on 50 cross-sections per sample. Mulberry silk grade 6A shows 10-11 micron diameter (finest), while tussah reaches 25-35 microns. This measurement directly determines hand feel fineness, brightness and fabric lightness. The protocol follows ISO 137 (textile fiber diameter) adapted for silk filaments by ISO/TC 38/SC 23.
Step 2: Tensile strength testing
Tensile strength (grams per denier) is measured on Instron dynamometer per ISO 5079 (single fiber tensile tests). Each filament is tested at 20 mm gauge length and 20 mm/min deformation rate. Mulberry typically reaches 4.0-4.8 g/denier, muga 5.0-5.5 g/denier (strongest natural silk) and tussah 2.5-3.5 g/denier. For reference, cotton reaches 3-4 g/denier and nylon 6-9 g/denier.
Step 3: Luster measurement
Silk luster is quantified by fixed-angle spectrophotometry (60 degrees) per ASTM D523. Mulberry charmeuse grade 6A achieves highest values (85-92 GU), followed by muga (80-88 GU, unique golden luster), while eri silk shows more subdued luster (35-45 GU). Degumming (sericin removal) increases luster by 30-40% by exposing crystalline fibroin.
Step 4: Drape coefficient
Drape coefficient is measured on Cusick Drape Tester per BS 5058. A 30 cm circular sample is placed on an 18 cm disc and the projected fallen area is measured by image analysis. High coefficient (above 85%) indicates fluid drape (chiffon, crepe de Chine), while low coefficient (30-50%) indicates structured fabric (dupioni, organza).
Step 5: Chemical analysis and certifications
Chemical analysis includes FTIR spectroscopy to verify composition (fibroin/sericin), chromatography for treatment residue detection, and OEKO-TEX Standard 100 testing. Sericin (20-30% of raw cocoon) is a key marker: residual content after degumming influences hand feel, luster and dyeability. GOTS certifications are verified with certifying bodies. Amino acid analysis distinguishes mulberry silks (rich in glycine, alanine, serine) from tussah silks (rich in alanine, glycine).
Cross-verification and sources
Every data point underwent triple verification: our lab measurements, ISC data and peer-reviewed TRJ publications. Discrepancies above 10% trigger additional testing by a COFRAC-accredited third-party lab. Prices verified via Shanghai and Bangalore exchanges plus three European specialists. Production data from FAO and ISC 2023-2025 annual reports.
Limitations and caveats
Silk quality varies significantly by terroir, season and rearing conditions. Spring mulberry (China, March-April) is generally superior to autumn silk. Wild silks show higher batch-to-batch variability. Scores represent averages over 5+ samples, with error margins of plus or minus 3 points for physical criteria and plus or minus 8% for prices. Spider silk (Nephila) is included experimentally: data from scientific literature, not commercial tests.

Frequently asked questions: luxury silks
Everything about silk varieties, quality, sourcing and care. Data from International Sericultural Commission, Textile Research Journal and ISO standards.
What is the difference between mulberry and wild silk?
Mulberry silk (Bombyx mori) is produced by domesticated worms fed exclusively on mulberry leaves, representing 95% of global production. Its continuous filament (1,000-1,500 m) offers ultra-fine 10-13 micron diameter, intense satin luster and perfect regularity. Wild silks (tussah, eri, muga) come from non-domesticated moths: shorter filaments (300-700 m), thicker (25-35 microns), naturally irregular texture. Wild silk is 30-40% more UV-resistant and generally more durable (10,000+ Martindale vs 5,000-8,000 for mulberry). Prices: mulberry 6A 60-95 USD/kg, tussah 35-55 USD/kg, muga 250-400 USD/kg.
What is the silk grading system (2A to 6A)?
The A grading system classifies mulberry silk from 2A (lower quality) to 6A (supreme quality). Criteria include filament length (6A = 1,200-1,500 m continuous), yarn regularity (6A = less than 2% variation), absence of defects, luster and natural whiteness. Grade 6A comes exclusively from spring harvest (March-April) in Suzhou and Hangzhou. For Misciano scarves, we use exclusively 5A-6A grade. Price difference between 3A and 6A is 40-60%.
How does silk compare to synthetic fibers?
Silk outperforms synthetics on several key metrics: breathability (Ret 4-6 vs 12-16 for polyester), moisture absorption (11% vs 0.4%), natural thermal regulation, antistatic without chemical treatment, hypoallergenic and biodegradable. Polyester wins on durability (20,000+ Martindale), dimensional stability and price (5-10x cheaper). Silk's strength-to-weight ratio (4.5 g/denier) is comparable to Kevlar.
How to care for silk garments?
Hand wash in lukewarm water (max 30C) with pH-neutral silk detergent. Never wring or machine spin. Dry flat, in shade (UV degrades fibroin). Iron at low temperature (max 150C, silk setting) on reverse with protective cloth. For stains: gently dab with damp cloth, never rub. Dry cleaning with perchloroethylene is acceptable but should be limited. Store in cotton fabric (not plastic) with cedar balls against moths.
What is momme and how to choose?
Momme (mm) is the silk weight unit: weight in pounds of a 45-inch by 100-yard piece. 1 momme equals approximately 4.34 g/m2. Choice depends on use: 5-8 mm for veils and chiffons, 12-16 mm for scarves and blouses, 19-22 mm for dresses and pillowcases, 25-30 mm for premium items. Higher momme means more opaque, durable and heavier fabric. Misciano scarves use 14-16 momme charmeuse and 12-14 momme twill.
Is silk an ecological fiber?
The environmental balance is nuanced. Positives: 100% natural and biodegradable, very low water use (vs cotton), mulberry grows without pesticides, sericin by-product used in cosmetics. Concerns: conventional sericulture kills the worm, carbon footprint of Asia-Europe transport, dyeing chemicals. Alternatives: eri silk (cruelty-free), peace/ahimsa silk, GOTS and OEKO-TEX certifications. Carbon footprint: silk 17-20 kg CO2/kg vs polyester 5-6 and organic cotton 8-10.
Why is muga silk so expensive?
Muga silk (Antheraea assamensis) combines multiple rarity factors: only 150 tonnes annual production (vs 180,000 for mulberry), production limited to Brahmaputra valley in Assam, impossible to fully domesticate, ancestral Bodo and Mishing community skills, unique natural golden color, exceptional durability (12,000 Martindale). A traditional muga sari costs 2,000-5,000 USD and is passed through generations. Protected by Indian Geographical Indication since 2007.
How to distinguish real silk from imitation?
Burn test (most reliable): silk burns slowly with burnt hair smell, leaving friable black ash. Polyester melts into hard bead with chemical smell. Touch test: silk feels warm (thermoconduction), smooth but not slippery like polyester. Friction test: vigorous rubbing warms silk (fibroin absorbs energy). Water drop test: water penetrates silk in 1-2 seconds (11% absorption), stays on polyester surface. Verification: request certificate of origin and A grading.
What are the main silk-producing countries?
China: 83% of global production (150,000 tonnes/year), main centers in Suzhou, Hangzhou, Chongqing. India: 15% (28,000 tonnes), mainly Karnataka (mulberry), Jharkhand (tussah), Assam (muga, eri). Uzbekistan: 1,000 tonnes. Thailand: 680 tonnes (Jim Thompson silk). Brazil: 600 tonnes (mulberry). Japan: 200 tonnes (residual, research). Italy (Como): no sericulture but world center for luxury weaving and dyeing. France (Lyon): historic silk expertise, marginal production since 19th century.
What is spider silk and why is it so sought after?
Spider silk (mainly Nephila clavipes and N. madagascariensis) is the strongest known fiber: 6-8 g/denier tensile strength (vs 4.5 for mulberry), 30-40% elasticity (vs 15-20% for mulberry), absorbs 3x more energy before breaking than Kevlar. Production is extremely difficult: a spider produces milligrams per day, and spiders are cannibalistic. Price exceeds 35,000 USD/kg. Current applications are biomedical (sutures, artificial tendons) and military (body armor). Companies like Bolt Threads and AMSilk produce recombinant spider silk via fermentation.
