OriginThe country is established by the laboratory from the inclusions and the chemical composition of the stone. The exact mine is stated only when we can prove it: otherwise we write Colombia and nothing more.

WeightThe carat is a unit of mass, not of size: 1 ct equals 0.2 gram. Two stones of the same weight can look very different depending on their cut. Rely on the dimensions in millimeters just below.

ColorThis is the first price criterion on an emerald. What is sought is a sustained green, neither too dark, which would deaden the stone, nor too light, which would strip it of presence. The video on the listing shows the real color, without retouching.
Vert intense
Shape & cutThe emerald cut, rectangular with clipped corners, protects a fragile material and brings out depth of color rather than sparkle. Pear, cushion and oval serve the same ends with a different silhouette.
Emeraude
TreatmentNearly all the emeralds on the market are oiled: a colorless oil fills the open fissures and makes the stone easier to read. The practice is old, accepted and reversible. The degree and the mention in brackets are copied from the certificate, exactly as the laboratory measured them.

Description of the stone
Colombian emerald of 4.89 ct, step cut as a square with cut corners — the centerpiece of this selection. Its intense green, deep and even, is that of the great Colombians: dense without ever going out, luminous without ever paling.
At this volume, such a color becomes exceptional: the eye plunges into a rich material, barely veiled by a discreet jardin that attests to the natural origin of the crystal. Minor oil — a minimal enhancement for a stone of this calibre.
The cut was recut underneath in order to bring out its clarity .
An emerald for a collection or for fine jewelry, to be mounted as a unique piece. Photographs and video of the exact stone, without retouching.

Frequently asked questions
What is treatment/oiling and is it normal?
Almost all natural emeralds show some oiling, an old and recognized practice that improves the legibility of the stone. The exact degree (no oil, minor, moderate) appears on the certificate and directly influences the price.
Is the color true to life?
Our photographs and our video show the exact stone, with no retouching at all. But the color of an emerald is never fixed: it changes with exposure to light. The same green will look deeper in daylight, warmer under a lamp, darker in shade. That is true of every emerald, not only ours.
This is why video remains the most faithful rendering: the stone moves, and you see it from several angles and under several angles of light, as if you were holding it. If you want to see it in other conditions, ask us for an extra video: we will film it and send it to you.
How do delivery and insurance work?
Every stone is shipped by DHL Express, insured and signed for on delivery, and travels with its certificate. France: 1 to 2 business days by Express, 3 to 5 business days by Standard. European Union and international: 3 to 5 business days.
Documented provenance
Journey of this emerald
This emerald is one of the pieces whose journey has been documented by Johya from the rough stone through to its certification.
01
1 / 2
Rough stone
Crystal bought hand to hand on the Muzo marketplace, in Boyacá. At this stage nothing is settled: the lamp hints at the color and the clarity, only the cut will tell what the stone can give. We selected it for the density of its green and the cleanness of its material, rare at such a size.

Cutting
The crystal travels down to Bogotá, entrusted to Christian, our lapidary. He opts for a square step cut with cut corners: it is the one that best respects the volume of the rough and circulates the light without hardening the color. Some material is always lost at this stage; that is the price of a properly proportioned stone.

Cut stone
4.89 ct out of the workshop, an intense green served by a lively brilliance. The stone is reweighed, photographed without retouching, then prepared for its departure to France. Its oil treatment, minor oil, is declared on its product page as on its certificate.
In an emerald, color sets the price before anything else. Three things are looked at: hue, which runs from slightly bluish green to slightly yellowish green; saturation, that is the intensity of the green; and tone, from lightest to darkest. The intense, slightly bluish green of the Colombian deposits is the most sought after.
A stone that is too dark loses its brilliance; one that is too light loses its presence. The balance point is judged by eye, never from a specification sheet alone: that is why every stone is filmed.
The jardin of inclusions
The inclusions of an emerald are called the jardin. They are normal and expected: an emerald with no visible inclusion at all is so rare that it should first raise the suspicion of a synthetic. The jardin is also what allows a laboratory to link a stone to its deposit.
What matters is not their absence but their position: inclusions at the periphery are less troublesome than a fracture in the middle of the table, which catches the eye and weakens the stone.
The origin of the deposit
Colombia has historically produced the most sought-after emeralds, around three zones: Muzo, Coscuez and Chivor. Muzo is associated with a deep, slightly yellowish green, Chivor with a bluer green. Origin is a laboratory determination, based on inclusions and chemical composition, not a commercial claim.
When we cannot prove the exact mine, we write Colombia and nothing more.
Oiling and its grading
Nearly all the emeralds on the market are oiled: a colorless oil fills the fissures open at the surface and makes the stone easier to read. The practice is old, accepted and reversible. What must be declared is the degree: none, insignificant, minor, moderate, significant.
A hardening artificial resin, on the other hand, is not equivalent: it cannot be removed the way an oil can. The certificate supplied with each stone states the measured degree and the nature of the filling material, without any interpretation on our part.
The cut
The emerald cut, rectangular with clipped corners, was designed for this stone: it limits stress on a fragile material and brings out depth of color rather than sparkle. Pear, cushion and oval serve the same ends with a different silhouette.
A good cut is judged by the even distribution of color and the absence of dead zones, not by a brilliance index borrowed from the diamond: those optical measurements make no sense on an emerald.
