Cold Dew: The Solar Term That Follows White Dew

On 8 October 2026, at around half past seven in the morning British time, the sun reaches 195 degrees of ecliptic longitude. In the Chinese agricultural calendar that moment has a name: 寒露, Cold Dew. It is the seventeenth of the twenty-four solar terms, and it marks the fortnight in which dew stops being merely visible and starts being cold to the touch.

We named our autumn collection after White Dew, the solar term a month earlier. Cold Dew is what comes next, and it is the point where autumn stops behaving like a cooler summer. The mornings are properly cold now rather than fresh; the light comes in at a low angle all day instead of only at the edges. This piece is about what the term actually means, where the name comes from, and why a small jewellery studio in Britain keeps time by a Chinese farming calendar at all.

Where Cold Dew sits in the year

The twenty-four solar terms divide the year by the sun's position rather than by the calendar. Each term begins when the sun reaches a particular point on the ecliptic, fifteen degrees apart, which works out at roughly a fortnight each. Because the terms are astronomical rather than conventional, their dates shift by a day or so from year to year — they are not fixed to the Gregorian calendar, they only appear to be.

The autumn run goes like this, with the 2026 dates:

• White Dew (白露), 165° — 7 September
• Autumn Equinox (秋分), 180° — 23 September
• Cold Dew (寒露), 195° — 8 October
• Frost's Descent (霜降), 210° — 23 October

Cold Dew therefore runs from 8 October until Frost's Descent on the 23rd. After that comes Beginning of Winter, and the autumn sequence is finished.

Three names for one substance

The thing that makes this stretch of the calendar unusually elegant is that three consecutive terms describe the same substance at three temperatures. At White Dew, moisture condenses overnight and becomes visible on the grass — white, in the sense of newly apparent. At Cold Dew, that same dew is cold enough to feel through a sleeve, sitting a few degrees above freezing. At Frost's Descent, it stops being water altogether.

It is a thermometer written as poetry, and it is the reason the terms are more useful than the four seasons. "Autumn" covers eleven weeks in which almost everything changes. White Dew, Cold Dew and Frost's Descent describe three distinct fortnights that anyone who goes outside early can tell apart.

The language goes back a long way. There is a line in the Book of Songs, compiled well over two thousand years ago, about reeds on a riverbank and white dew turning to frost — a person standing at the water's edge in the cold, looking for someone on the far side. One of our necklaces, Reed Bank, takes its name from that line.

What the old almanacs recorded

Each solar term was traditionally subdivided into three pentads of roughly five days, each with a phenological note attached. For Cold Dew, the three are:

1. Wild geese arrive as guests — the last of the migrating geese come through, late and in smaller numbers than at White Dew.
2. Sparrows enter the water and become clams — birds grow scarce on the shoreline as shellfish become abundant, and the observer draws a connection that is charming rather than correct.
3. Chrysanthemums bear yellow flowers — the one flower that reliably opens as everything else is closing.

These are observations from one particular climate a very long time ago, not a field guide. The clam line is obviously a misreading of what was in front of someone. But the chrysanthemum note still holds in Britain, and the Double Ninth Festival, which involves chrysanthemum wine and walking up hills, usually lands within the Cold Dew fortnight. In 2026 it falls on 18 October.

Why a jewellery studio keeps a farming calendar

The honest answer is that it imposes a useful discipline. Most jewellery is designed against season names that mean very little — a collection described as autumn/winter is really a shipping window. The solar terms give us something narrower to work towards: not autumn, but these fifteen days, with this quality of light and this temperature at seven in the morning.

That is what "wear a small piece of season" is meant to describe. Not a mood board, but a fortnight you could point to.

Practically, it shows up in colour. The White Dew collection is built around citrine, clear quartz and freshwater pearls — warm gold against soft white, which is what the fields and the mornings looked like in early September. Cold Dew sits later and lower. The gold is still there but it has less sun behind it, and the blues start to make sense again: lapis lazuli, aquamarine, smoky quartz, the palette we work in for Blue Reverie.

Both collections are strung by hand in our UK studio, which means the transition between them is gradual rather than a launch date. Pieces overlap. That suits a calendar built on fortnights.

What to reach for in the Cold Dew weeks

This is the point in the year when jewellery has to work with wool, and that changes which pieces get worn.

Bracelets become the easy answer, because they sit below a cuff and get seen every time you push a sleeve up. Dew Light is a freeform Brazilian citrine held between round freshwater pearls and small citrine chips, at £69; the bracelet is made in three sizes across a 14.5–18 cm range, so measuring your wrist is worth the thirty seconds.

Necklaces need length. Anything that sits at the collarbone disappears under a crew neck, so a long strand worn in one loop over a jumper tends to read better than a short one fighting with a collar. Pieces designed to be doubled are more useful in October than in July for exactly this reason.

Pearls are worth defending here. They are often treated as summer stones, which is a mistake — nacre against dark wool is one of the better contrasts available, and the low autumn light does more for a baroque surface than bright sun does.

What the heating does to your jewellery

The practical cost of October is that central heating comes on and indoor humidity drops. Freshwater pearls are organic, soft at roughly 2.5 to 4.5 on the Mohs scale, and they do not like being dried out or kept somewhere airless for months. Neither does knotted thread.

Three habits cover most of it. Put jewellery on last, after perfume and moisturiser have dried. Wipe pearls with a soft dry cloth when you take them off, because skin oils and hairspray sit on nacre rather than rinsing away. Store pieces flat and separately rather than in a heap, so faceted stones are not grinding against softer ones in a drawer. There is more detail in our jewellery care guide, including what to keep away from water and how to look after elastic and silk cord.

Common questions

When is Cold Dew in 2026?

8 October 2026. The term runs until Frost's Descent on 23 October. The dates move by a day either way between years because the terms are set by the sun's position, not by the calendar.

What is the difference between White Dew and Cold Dew?

About a month, and several degrees. White Dew, in early September, is when overnight condensation first becomes visible. Cold Dew, in early October, is when that dew is cold to the touch and close to freezing. Frost's Descent, at the end of October, is when it freezes.

Is Cold Dew a festival?

No. The solar terms are calendar markers rather than holidays, and most pass without ceremony. Cold Dew happens to sit near the Double Ninth Festival, which is a festival, but the two are separate things.

Why name collections after solar terms instead of seasons?

Because a fortnight is specific and a season is not. Naming a collection White Dew commits us to a particular week of the year, a particular temperature and a particular colour of light. Naming it autumn commits us to nothing.

Does citrine have a traditional meaning?

In the lapidary traditions that got passed down through European and Chinese sources, yellow stones were associated with warmth, sunlight and good fortune, and citrine in particular with prosperity. These are cultural and historical associations rather than properties of the stone, and we would not present them as anything more than that. If you are drawn to citrine, it is most likely because it is a very good colour in October.

Can freshwater pearls be worn every day through autumn and winter?

Yes, with the ordinary caution. Pearls are softer than most gemstones and dislike acids, alcohol and abrasion, so they want to go on after perfume and come off before washing up. Daily wear is otherwise good for them; it is long storage in a sealed box that does the damage.

Which piece suits someone who has never worn pearls?

Something fine and short rather than a full strand. A single cluster at the collarbone reads as a necklace that happens to contain pearls, rather than as pearls, and it layers under a shirt collar without announcing itself. Grass Dew, at £59, is the piece in the White Dew collection built on that principle: a fine line of flat freshwater pearls with a small cluster of peridot and citrine at the front.

Do solar terms make sense outside China?

Partially. The astronomy is the same everywhere in the northern hemisphere — the sun reaches 195 degrees at the same moment whether you are in Shaanxi or Shropshire. The phenology is local: the almanac's geese and chrysanthemums describe the Yellow River basin, and a British October runs wetter and milder. The framework travels; the details need rewriting for where you are.

After the eighth

What we like about Cold Dew is how modest it is. There is no feast attached, no gift-giving obligation, nothing to prepare. It simply records that the dew is colder than it was a fortnight ago, and that in another fortnight it will be frost. The whole calendar is built like this — twenty-four small, accurate observations about things most people stop noticing after childhood.

Jewellery can work the same way. A bracelet you put on in the dark at seven in the morning is not an occasion. It is a note to yourself about what time of year it is.
