The silk anniversary falls in the twelfth year on the most cited list, that of British and American etiquette, where silk sits alongside linen. Another British list and many Italian lists bring it forward to the fourth year, again paired with linen. The two dates coexist: the one the couple recognises is the one that counts. Below, where each comes from and what to give.
Anyone who wants the smooth feel of silk in a machine-washable item usually looks at the Looniva bed sets, in 300TC bamboo viscose certified OEKO-TEX Standard 100 class I, from €79.
The two dates for silk
Anyone searching for how many years the silk anniversary is will find two answers, and both have a source. The British etiquette list assigns silk to the twelfth year, together with linen, and puts flowers and fruit at the fourth (source: Debrett's, guide to wedding anniversaries). The traditional American list does the same: silk at the twelfth, flowers and fruit at the fourth.
The other date comes from another British list, that of the Pears encyclopaedia in the 1978-79 edition, which puts linen and silk at the fourth year (source: Wikipedia, entry Wedding anniversary, table of traditional lists). Many Italian lists report this date, sometimes as the silk anniversary and sometimes as the linen or silk anniversary.
The full table is in the guide to wedding anniversaries year by year, which follows the main list.
Why silk sits so high on the list
The anniversary list moves from the fragile material to the one that lasts: paper in the first year, cotton in the second, up to the silver and gold that the dictionary records under the entry nozze (source: Treccani). Silk, in the main version, comes after the steel of the eleventh year: it is the only precious fibre among the first fifteen years.
The placement is explained by the history of the fabric. Silk was born in China, reached the Mediterranean in 552 with cocoons brought by two monks sent by Justinian, and entered Italy in 1146 with Roger II in Sicily (source: Treccani, entry seta).
). The fibre too has something rare about it. A silkworm cocoon contains a continuous filament of 700-800 metres, made of two proteins: fibroin, which makes up 72-76 per cent of the weight, and sericin, which holds it together and is removed with hot water during processing (source: Treccani, entry seta). At the twelfth year the list puts a thread that no household could produce for itself.
Where silk at the fourth year comes from
In the Pears list the fourth year pairs linen and silk, the two fibres that in the main version sit together at the twelfth. The meaning stays the same: after paper, cotton and leather, the fourth year brings the first fine fabric, the kind that is kept.
The Italian lists take up the English and American ones, and each chooses a variant: the fourth year appears as the linen, silk, flowers or fruit anniversary. Neither date is wrong: anyone celebrating the fourth anniversary and calling it the silk anniversary is following a documented list.
The same happens with the second year, which some lists call porcelain: the case is explained in the guide to the cotton anniversary, the second anniversary.
What to give for 4 years of marriage
The material of the year points to a category of gift, and at the fourth year the category is fine textiles. It is a gift that gets used, and household linen is the most direct case.
A pure silk item works if the person receiving it has time to look after it. Silk is washed by hand in lukewarm water, with a soak of 10 minutes at most and a specific detergent or a mild soap (source: GINETEX, washing silk). On a scarf or a pillowcase it is manageable; on a whole bed washed every week it becomes a commitment.
Anyone who wants to stay on theme without imposing that upkeep has three routes: a silk accessory, a fabric that recalls its feel, or the linen of the variant. The ideas gathered by occasion, from the first year onwards, are in the guide to the wedding anniversary gift, and the reasoning on why the bed works as a gift is in the one on bed linen as a gift.
The smooth feel of silk in a machine-washable item
Bamboo viscose is often compared to silk to the touch: both have a long, continuous filament, without the short ends that in cotton stay on the surface. The difference lies in the origin. Silk is a protein spun by the silkworm, viscose is cellulose regenerated from the pulp of the plant.
On moisture the two fibres are close. Silk retains about 11 per cent of its weight in standard conditions (source: ASTM D1909), bamboo viscose 13 per cent against 0.4 per cent for recycled polyester (source: Journal of Natural Fibers, 2025). Care is what changes: viscose goes in the washing machine on a delicate programme at 30 degrees, and the step-by-step instructions are in the guide to how to wash bamboo sheets without damaging them.
The full comparison between the two fibres, point by point, is in the guide to silk or bamboo sheets. For a gift the point is simple: silk asks for time from the person who receives it, bamboo viscose asks only for a washing machine.
The Looniva Mezzaluna bed set brings together fitted sheet, flat sheet and two pillowcases in 300TC bamboo viscose, at €169 in the double size and €129 in the single. The fabric is certified OEKO-TEX Standard 100 class I, the class intended for articles for babies.
Before buying: the size
With a bed linen gift the most concrete risk is the size. Before choosing it is worth knowing the width of the mattress, because the fitted sheet must be that width and no other: the combinations are in the guide to double sheet sizes.
For a more complete gift you can go for the bamboo set with duvet cover, which at €249 in the double size adds the duvet cover to the four pieces, and if the gift is for a couple who have just moved house, the ideas on couples' gifts for the home.

- A single cocoon contains a filament 700-800 metres long, 72-76 per cent of it fibroin (source: Treccani, entry seta)
- Silk is washed by hand in lukewarm water, with a soak of 10 minutes at most (source: GINETEX, washing silk)

Frequently asked questions
How many years of marriage is the silk anniversary?
On the most cited British and American list it is twelve years, with silk alongside linen. Another British list, that of the Pears encyclopaedia of 1978-79, puts linen and silk at the fourth year, and many Italian lists report this date. Both are documented.
Why do some lists put silk at the fourth year?
Because the Italian lists take up the English and American ones, and each chooses a variant. The Pears list pairs linen and silk at the fourth anniversary, Debrett's puts them at the twelfth. The meaning does not change: the fourth year brings the first fine fabric.
What do you give for 4 years of marriage?
A fine textile, as the list suggests: a silk accessory, a linen item, or bed linen with a smooth feel. If the gift is to be used every week, a machine-washable fabric is best, because pure silk needs hand washing.
Can you give bamboo bed linen for a silk anniversary?
Yes, if you are looking for the smooth feel of silk in a machine-washable item. Looniva sets are in 300TC bamboo viscose, a fibre that retains 13 per cent of its weight in moisture, and the double Mezzaluna set costs €169. Returns are within 30 days for unused items.
