Aquamarine

AQUAMARINERough Gemstones & Semi-precious1 listed market

Aquamarine is the blue to blue green variety of beryl, the same mineral species as emerald, coloured by iron in the crystal structure. It grows in granitic pegmatites as hexagonal prisms that can reach great size and remarkable clarity, which is why it is one of the few gemstones routinely cut in large, clean, faceted stones. It is used in fine jewellery, in carving and in collector specimens, and its hardness and the availability of clean material make it a staple of commercial and designer jewellery alike.

Listed aquamarine markets

Each line is a grade at a delivery point. Open one for its full specification and terms.

Grades

Aquamarine is bought on colour first, then on clarity and on what the crystal will yield. The rough is sold as crystals, as preformed pieces or as sorted parcels, and the contract fixes the species, the colour description, the treatment disclosure and the weight.

Species, variety and identification

8 grades

Determined by gemmological testing against the constants of the species, and reported under the trade nomenclature standardWhat the stone is. Identification comes before every other term, because the species fixes the constants a laboratory will test against and the name that may lawfully appear on the invoice.

GradeDefinition
SpeciesBeryl, confirmed by gemmological testingConfirmed against the constants of beryl, refractive index, birefringence and specific gravity, on every parcel where identity is not already established by a laboratory report.
VarietyAquamarineThe blue to blue green iron coloured variety. The variety name may only be used where the colour falls within it under the trade nomenclature standard.
Colouring elementIron, in two oxidation statesFerrous iron gives the blue, ferric iron gives the yellow that reads as green. The balance between them is what heating changes.
Refractive indexReported, with the birefringenceMeasured on a refractometer. It separates beryl from the blue stones that imitate it.
Specific gravityReportedMeasured hydrostatically, confirming the species and flagging a substitute.
HardnessReported on the Mohs scaleThe wear resistance a jeweller and a setter plan around.
PleochroismDeclared, as the two observed coloursBeryl is dichroic. The orientation of the table to the optic axis decides which colour the finished stone shows, and it is a cutting instruction as much as a property.
Crystal habitDeclaredHexagonal prism, with the terminations, the etching and the striation described, because they govern how the piece is sawn.

Colour

6 grades

Described by hue, tone and saturation under controlled daylight equivalent lighting, against the trade nomenclature standardColour is the dominant value driver in a coloured stone. It is described in three separate dimensions rather than reduced to a single word, and the lighting condition is named because the stone can shift.

GradeDefinition
HueDescribed, from blue to green blue to blue greenThe primary and any secondary hue, named in that order. Pure blue with no green modifier commands the premium.
ToneDescribed, from light to darkHow light or dark the stone reads. Aquamarine is a naturally light stone and tone is the term that most often separates commercial from fine.
SaturationDescribed, from weak to vividThe intensity of the hue, judged with the tone rather than separately.
Colour zoningDescribed, by location and intensityBeryl grows in colour zones along the prism. Where the zoning sits decides how the stone must be oriented and whether the colour will spread when cut.
Lighting conditionDeclaredColour assessed under daylight equivalent lighting, with any change under incandescent light noted.
Colour stabilityDeclaredWhether the colour is stable to light and heat in normal wear, which for iron coloured beryl it is.

Clarity and inclusions

5 grades

Observed at ten times magnification and confirmed under the microscope, against the clarity type of the speciesClarity is judged against what is normal for the species. A stone that is expected to grow clean is held to a different standard than one that never does.

GradeDefinition
Clarity typeType one, under the standard clarity classificationAquamarine is expected to grow eye clean. It is graded against that expectation, so a visible inclusion carries more weight here than in a stone that never grows clean.
Eye clean assessmentDeclared, at the stated viewing distanceWhether inclusions are visible to the unaided eye at the normal viewing distance, which is the working commercial threshold.
Inclusion typesDescribedLiquid and two phase inclusions, hollow tubes parallel to the prism, growth tubes and mica plates. The suite is also part of an origin opinion.
Fractures and cleavageDescribed, by position and reachBeryl has an imperfect basal cleavage. A fracture reaching the surface is a durability and a yield term.
TransparencyDescribed, from transparent to translucentTransparent material is faceted, translucent material is cabbed or carved, and the split changes the price basis.

Rough form, size and yield

6 grades

Measured and weighed on the rough parcel, with the cutting assessment declaredRough is bought on what can be cut out of it. Weight, shape, and the way the crystal presents decide the yield, and the yield decides the price per carat.

GradeDefinition
Rough weightCarats, per piece and per parcelWeighed on a calibrated balance. Large clean beryl crystals are common enough that size alone does not carry the price.
DimensionsMillimetres, length by width by depthMeasured on the crystal or the preform, because the finished stone that can be cut from it is a dimensional question.
Estimated yieldPercentage of rough weight, declared as an assessmentThe cutting assessment, stated as an opinion of the seller or the inspecting cutter, never as a warranty.
Shape and formDeclared, as crystal, water worn piece, preform or sawn sliceWhat condition the rough arrives in, which sets the work still to be done.
OrientationDeclaredWhere the table will sit relative to the optic axis, which for a dichroic beryl decides the face up colour.
Size distributionDeclared, as the count within each stated weight bandFor a sorted parcel, the distribution rather than the average, because a parcel is bought on what it will produce across the sizes.

Treatment and disclosure

6 grades

Disclosed in full under the trade nomenclature standard and the laboratory harmonisation information sheetsEvery treatment is disclosed, permanent or not. Non disclosure is the single fastest way to destroy a counterparty relationship in this trade, so the disclosure travels on the contract, the invoice and the parcel.

GradeDefinition
Heat treatmentDisclosed, as heated or unheatedLow temperature heating drives ferric iron toward ferrous and removes the green, leaving a purer blue. It is routine, permanent and stable, and it must be disclosed.
IrradiationDisclosedDisclosed where used, with the process named.
Fracture fillingDisclosed, with the filler identifiedAny resin, oil or glass in a fracture, identified by the laboratory and disclosed with the extent.
Coating and surface treatmentDisclosedAny applied layer, disclosed with its coverage and its durability.
Synthetic and imitation screeningDeclared, against the named laboratory methodConfirmation that the material is natural beryl rather than synthetic beryl, glass, or another blue species.
Disclosure recordDocument, per parcelThe written treatment disclosure travelling with the invoice and the parcel, as the trade standard requires.

Parcel, documentation and settlement

9 grades

Contract terms settled on the parcel, the laboratory report and the export documentation rather than on the stone itselfTerms that travel with the parcel.

GradeDefinition
Parcel compositionDeclared, by piece count and total carat weightWhat is actually in the lot. A rough parcel is sold as a parcel, so the count, the weight and the size distribution are the contract.
Weight basisCarats, to the stated decimal placeWeighed on a calibrated balance, with the weighing certificate and the tolerance named.
Sealing and markingDeclaredParcels sealed in the presence of both parties or their agents, numbered and photographed, so the goods that arrive are the goods that were inspected.
Laboratory reportDocument, per stone or per parcelIssued by a named laboratory operating to the international testing competence standard, covering species, treatment and, where commissioned, origin.
Origin determinationDeclared, where commissionedA laboratory origin opinion is an opinion based on inclusion suites and trace element chemistry. It is stated as such and never as a guarantee.
Export and import documentationDeclaredExport permit or certificate from the producing country, customs classification under the harmonized system, and any royalty or clearance certificate the origin requires.
Responsible sourcingDeclaredMine or source, chain of custody, and the due diligence statement, including artisanal and small scale mining status where it applies.
Viewing and rejectionDeclaredWhere and when the buyer may view, the memo or consignment terms if any, and the window and grounds for rejection after the laboratory report.
Insurance and carriageDeclaredValuation for transit, the specialist carrier or secure courier named, and the point at which risk passes.

Timing

Production is when the stone comes out of the ground at origin, which follows the mining season, the water level at an alluvial working and the rhythm of artisanal digging rather than a crop calendar. Arrival is when material from that origin typically reaches a cutting or trading centre. The gap between them is sorting, export clearance and the journey to the market.

Every grade is tied to a delivery point and a settlement route. Grades outside the published list are priced on request.

How is aquamarine graded?

Aquamarine is bought on colour first, then on clarity and on what the crystal will yield. The rough is sold as crystals, as preformed pieces or as sorted parcels, and the contract fixes the species, the colour description, the treatment disclosure and the weight. Grading runs on 6 systems: Species, variety and identification, Colour, Clarity and inclusions, Rough form, size and yield, Treatment and disclosure and Parcel, documentation and settlement.

Where does SIP Global trade aquamarine?

We trade aquamarine in Brazil, Madagascar, Nigeria, Zambia, Pakistan, Afghanistan, Nepal and Sri Lanka and 34 further markets. Origins and destinations outside this list trade on request. We are not limited to the locations shown.

When is aquamarine harvested and when does it arrive?

Typical windows are Brazil: harvest jan to dec, arrival jan to dec; Madagascar: harvest apr to nov, arrival jun to jan; Nigeria: harvest oct to apr, arrival dec to jun; Zambia: harvest may to oct, arrival jul to dec; Pakistan: harvest may to oct, arrival jul to dec. Harvest is when the lot is taken at origin, arrival is when a shipment from that origin lands in a consuming market. Windows outside this pattern, including carry, trade on request.

What is the HS code for aquamarine?

Aquamarine is normally classified under HS 7103.10 (precious and semi-precious stones, unworked or simply sawn or roughly shaped) and HS 7103.99 (semi-precious stones, otherwise worked). The heading follows the form the goods are in at the border, and national tariffs extend it beyond six digits, so confirm the full line with the destination customs authority before you fix a contract.
