Jade Signet Ring, an Oval Green Jadeite Cabochon

64,90 €

Jade signet ring: a large oval jadeite cabochon in an intense green, on a square mount in bright silver-toned metal. Shoulders and flanks paved with small white stones.

A ring with character, at home on a man’s finger as on a woman’s. Broad mount: when in doubt, take the size above, a paved mount resizes badly.

Cabochon set, so not weighable. White stones not identified. Treatment status not determined.

How to measure your size: the guide, category by category

French sizing: the finger circumference in millimetres, so a 54 measures 54 mm.

A jade signet ring with an assertive character: a large oval jadeite cabochon, in an intense green, set on a square mount in bright silver-toned metal. Fine lines of small white stones underline its shoulders and its flanks.

In four lines

  • A large oval cabochon of jadeite, in an intense green.
  • A square mount, broad and polished, in silver-toned metal.
  • Shoulders paved with small white stones.
  • A ring with character, at home on a man’s finger as on a woman’s.

A green you see from across the room

This jade signet ring is built around its stone: an oval cabochon, high and well domed, in a clear, luminous green. The light rolls over the dome; where it strikes, the green lightens, and it deepens towards the edges, where the stone dives into the mount.

It is the green you expect from a jadeite, saturated and alive. It is noticed from a distance, even on a hand in movement, and that is the whole point of a ring of this build.

An architect’s mount

The mount answers the curve of the stone with straight lines: a square table, broad polished flanks, and two rounded shoulders that frame the cabochon at either end. On those shoulders and along the flanks, small white stones set in a line catch the light at every gesture.

The whole design rests on that contrast: the round of the stone, the square of the metal. For another jadeite cabochon, claw set, see also the jade cabochon ring.

The signet ring, a ring with character

The signet ring is the ring that signs. It once carried an engraved seal; today it is worn for its presence, and this one replaces the seal with a stone. In France, tradition places it on the little finger, but nothing stops you wearing it on the ring finger or the index, where it asserts itself more.

Its clean lines make it obvious on a man’s hand. It suits just as well a woman who likes strong rings, worn alone, with nothing around it. The jade jewellery that suits men.

Jadeite, the jade of vivid greens

The word jade covers two minerals. Jadeite is the one of the most vivid greens, which it owes to chromium; its very fine grain takes an almost glassy polish, and that is what makes a dome like this one shine. It is also the harder of the two, 6.5 to 7 on the Mohs scale. Jadeite or nephrite, what sets them apart.

Choosing your size well

Choose your size in the drop-down above the buy button: the French size is your finger circumference in millimetres. Measure in the evening, when fingers are at their largest. A broad mount grips more than a fine band: if you hesitate between two sizes, take the larger.

Choose it with care: a paved mount resizes badly, because the small set stones risk loosening when the metal is worked. Measuring your finger in two minutes.

Wearing it, and keeping it beautiful

A high cabochon is the most exposed part of a hand: take the ring off for sport, for DIY and for the weights room. Now and then, look at the small stones on the shoulders: a stone that moves is easily tightened by a jeweller, provided you notice it early. Hardness and toughness, the difference.

For care, a soft toothbrush, warm soapy water, then careful drying. If the metal dulls, a silver cloth, keeping away from the stone. Never ultrasonic, never steam, never solvent: ultrasound loosens small set stones, and the treatment status of the jade is not known. Care in detail.

What tradition attributes to a jade signet ring

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.

A stone of moral virtue In 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.
The ring that signed Engraved with arms or initials, the signet ring served to seal letters and deeds in wax. It was a signature worn on the finger, and that is where it gets its air of authority.
The green that won over the court Jadeite only reaches China in the eighteenth century. A century later, the dowager empress Cixi makes it her favourite stone, and its vivid green becomes the most sought after on the market.
Jade in the masculine In China, jade was long an attribute of men: pendants at the belt, seals, ornaments of rank. That it became mainly feminine in the West is a recent reversal.

These readings are told, not verified. Moral virtues in Confucius, the virtues attributed to jade, told honestly, and what jade has been in China.

A stone does not replace a doctor and treats nothing: the full warning is here.

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.

It is all set out here, with no small print.

The Simple Routine

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.

Cleaning a piece of jade jewellery and storing it.

What I Do, and What I Do Not Do

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.
