Men’s jade necklace, a flat, smooth rectangular plaque, polished on both faces, with no engraving at all. Drilled and threaded on a black braided cord.
The shape has a name in China, the no-business plaque: it is deliberately left blank. Flat, it lies on the breastbone instead of rolling and does not print through the fabric.
Cord adjustable by a sliding knot, no size to choose. No metal touches the stone: it is weighable, and the figure will be published here. Treatment status not determined.
A men’s jade necklace built on a rectangular plaque, flat, polished on both faces and with no engraving at all. It is drilled at the top and threaded on a black braided cord, with a small round jade bead above it. The green is deep, with lighter zones that shift with the angle.
In four lines
A flat, smooth plaque, polished on both faces, with no engraving at all.
Drilled and strung on a braided cord: no metal touches the stone.
Bare stone, therefore weighable: the figure will be published here, with its date.
The length of the cord is set by a sliding knot, not by a clasp.
A deliberately blank plaque
This shape has a name in China: the no-business plaque. It is a rectangular plaque deliberately left with no motif, no character and no engraving, as against the plaques loaded with dragons, phoenixes or inscriptions. Emptiness is the subject.
I am not going to claim an effect for it, this site claims none for any stone. But the shape is documented and old, which is more than can be said of most motifs sold today, and it has a very concrete merit: a smooth surface has neither hollows where a dye lodges, nor a fine edge that chips.
Flat, and why that is the right choice under a shirt
A flat plaque lies against the breastbone instead of rolling. It does not print through the fabric as a thick pendant would, and it does not turn on itself: as both faces are identical, that would make no difference anyway.
The cord is braided and adjustable: the length is taken at the sliding knot, so there is no size to choose above the buy button. A cord wears out before the stone, and it can be replaced. Thread and cord on a jade piece.
A deep green, and what can be read in it
The colour is clear, a little bottle green in places, lighter in patches, with a little light passing at the edges. That irregularity is what you expect from a natural material, where iron or chromium did not distribute themselves to order.
It is not proof for all that, and the treatment status of this piece is not determined, like that of this whole catalogue. What should alert you is the opposite: a colour rigorously identical everywhere, or concentrated around the drill hole and along micro cracks. Look at the plaque against the light, near a window. The checks that need no equipment.
Jadeite or nephrite, and why this page does not settle it yet
The two minerals are not related at all: jadeite is a sodium aluminium pyroxene, nephrite a calcium amphibole, and it was Alexis Damour who separated them in 1863, in the laboratory. What sets them apart.
By eye, on a deep green, the distinction is not reliable. Density, on the other hand, is: the two ranges do not overlap. That is the figure the weighing will give, and that is the day the Mineral line of the record will stop saying “or”. Meanwhile, jade is tough whichever of the two it is: a thin plaque holds because its interlocking structure stops cracks, not because it would be hard. The difference between hardness and toughness, and jade in the masculine.

What tradition attributes to the jade plaque
What follows changes register, and I flag it rather than blending it into the rest of the page. None of it is proven. These are customs and beliefs, old and documented, which I report because they are part of the history of this stone. No piece of jewellery in this shop is sold as a treatment, and I claim no effect for this one.
The stone worn against the skinJade takes the temperature of the body in a few minutes and keeps it. That is a physical property, conductivity, and several traditions have made something quite different of it. I stay with the first.
The no-business plaqueThe rectangular plaque left blank carries in Chinese a name that translates as no-business plaque, as against the plaques loaded with dragons or inscriptions. Emptiness is the subject there, and the shape is old.
A stone of moral virtueIn Confucian thought, jade is associated with qualities of character rather than effects on the body: uprightness, constancy, restraint. It is the best documented meaning of them all.
Jade in the masculineJade was long an attribute of men in China, worn at the belt and on the seal, before becoming a woman's jewel in the West. The reversal is recent and cultural, not ancient.

The Packaging, and Why It Matters
Every piece travels in its own pouch, kept apart from the others. This is not a question of presentation: the hardness of jade is unremarkable, between 6 and 6.5 for nephrite and 6.5 to 7 for jadeite, and the quartz in ordinary household dust sits at 7. Two pieces of jewellery that travel together arrive marked.
Fourteen Days to Change Your Mind
No need to give a reason. An email is enough to open a return; there is no form to fill in. Return postage is at your expense, unless the piece does not match its listing or arrives damaged.
Getting the size wrong is the most common reason for a return in this category, and jade cannot be resized the way a solid metal band can. Two minutes spent measuring almost always avoids it. The size guide.
Lukewarm water, mild soap, a soft cloth. A very soft brush for the hollows of a carving. That is all, and it is enough.
What You Must Never Do, and Why
No ultrasonic cleaners, no steam, no solvents, no heat source. This is not a precaution for show: the treatment status of my pieces is undetermined. My supplier does not know it, and weighing identifies the mineral without telling me anything about a possible resin impregnation. Resin withstands neither heat nor solvents, so every piece is handled as though it might contain some. The information sheet on treatments.
Scratches, and Where They Come From
Jade is tough, meaning very difficult to break: its structure of interlocking crystals resists cracking, and that is what made it usable for axe heads in the Neolithic. Its hardness, by contrast, is unremarkable, 6 to 6.5 for nephrite and 6.5 to 7 for jadeite. The quartz in ordinary household dust sits at 7: that is what dulls a jade, not knocks. The difference between the two.
Day to Day
Put the piece on after perfume and cream, never before. Take it off for housework, gardening and sport, where knocks against hard edges are common. Store each piece on its own, in its pouch. On a strand of beads, the thread wears out before the stone: it gets restrung, and there is nothing abnormal about that.
My name is Jade. French, from Morbihan, living in Tallinn. I choose the pieces and have them mounted: I mine nothing, I cut nothing, and the metalwork is not done by my hand. What I bring is the selection, and with this material that is what decides everything.
I am not a gemmologist, not a lapidary, not a therapist, and I do not claim to be.
I Weigh, I Do Not Certify
Before a listing goes online, I order one example of it for myself. When it reaches me unmounted, I weigh it in air, then suspended from a thread in a glass of water: the ratio of the two masses gives the density, and that figure separates jadeite, nephrite, serpentine and dyed quartzite without ambiguity.
One example per listing, and not every piece. I do not handle the piece that is sent to you, and I would rather write that down than let you believe otherwise. The method, with its three limits.
What I Cannot Know
The treatment status of my pieces. My supplier does not know it, and the scales do not tell me: they identify the mineral, not the resin impregnation. Only infrared spectroscopy in a laboratory would settle it, and I do not have that done. So you will never read “Grade A jadeite”, “Type A” or “untreated” on this site. The information sheet.
Where My Jade Comes From
No Burmese jadeite, and the first reason is legal. Not the one you read everywhere: the JADE Act of 2008 did ban these stones in the United States, but that ban was lifted on 7 October 2016. What applies today dates from 8 April 2021: the US Treasury sanctioned Myanma Gems Enterprise, the state company that controls the Burmese gem trade. So there is no blanket ban, but a US person is not allowed to trade with that entity, and a stone never tells you where it has been. A single supply chain serves ten markets, so it has to hold up in the most demanding of them. When an origin is not confirmed to me in writing, the listing does not state it. My origin charter.
