Clarity Characteristics
Internal and external features (inclusions and blemishes) used to determine a diamond’s clarity grade.
Saznajte višeCoating
A surface treatment that applies a thin layer to alter a diamond’s apparent colour; not permanent.
Saznajte višeCrown Angle
The angle between the bezel (crown main) facets and the girdle plane, influencing the balance of fire and brilliance.
Saznajte višeDepth Percentage

Saznajte višeDiamond Grading Report
A document issued by a gemological laboratory detailing a diamond’s 4Cs, measurements, and identifying characteristics.
Saznajte višeFancy Vivid
The highest colour saturation grade for fancy coloured diamonds, indicating the most intense and pure colour.
Saznajte višeFluorescence Grades
The five-point scale used to describe fluorescence intensity: None, Faint, Medium, Strong, and Very Strong.
Saznajte višeFracture Filling
A clarity treatment in which a glass-like substance is injected into surface-reaching fractures to reduce their visibility.
Saznajte višeFTIR
Fourier-transform infrared spectroscopy, used to classify diamond type (I/II) and detect certain treatments.
Saznajte višeHodnocení (grading)
Systematické posouzení kvality diamantu podle standardizovaných kritérií.
Saznajte višeHue
The dominant spectral colour of a fancy coloured diamond, such as blue, pink, or yellow.
Saznajte višeIrradiation
A treatment using electron or neutron bombardment to alter a diamond’s colour, often followed by annealing.
Saznajte višeKarat (zlato)

Kimberleyski proces
Mezinárodní certifikační systém zabraňující obchodu s konfliktními diamanty.
Saznajte višeLaser Drilling
A clarity treatment that uses a focused laser beam to create a channel to reach and bleach dark inclusions.
Saznajte višeLaser Inscription
A micro-engraving on the girdle of a diamond, typically the laboratory report number, used for identification.
Saznajte višeMeasurements (mm)
The length, width, and depth of a diamond recorded in millimetres on a grading report.
Saznajte višeMelee
Drobné diamanty (pod 0,2 ct), často používané jako doplňkové kameny.
Milky Diamond
A diamond with reduced transparency caused by sub-microscopic inclusions or structural irregularities.
Saznajte višePřírodní diamant
Diamant nastanaklý přirozenými geologickými procesy v zemljinom plaštu.
Saznajte višeOverweight Diamond
A diamond cut deeper than ideal proportions to retain carat weight, resulting in a smaller face-up appearance.
Saznajte višePavilion Angle
The angle between the pavilion main facets and the girdle plane, critical for light return and brilliance.
Saznajte višePhotoluminescence (PL)
A spectroscopic technique using laser excitation to identify defect centres and detect treatments in diamonds.
Saznajte višePlot
A diagram on a grading report that maps the location and type of a diamond’s clarity characteristics.
Saznajte višePolish
The quality of a diamond’s surface smoothness resulting from the cutting and polishing process.
Saznajte višeProportions Diagram
A profile view on a grading report showing key angles, percentages, and measurements of a diamond’s cut.
Saznajte višeSaturation
The intensity or purity of a fancy diamond’s colour, ranging from weak to vivid.
Saznajte višeSpread
The face-up size of a diamond relative to its carat weight; a well-spread stone looks larger for its weight.
Saznajte višeStrain Patterns
Internal stress features visible under cross-polarised light; their character differs between natural and lab-grown diamonds.
Saznajte višeTable Percentage
The width of the table facet divided by the average girdle diameter, expressed as a percentage.
Saznajte višeNapínací zasazení
Kámen držený tlakem kovových ramen — zdánlivě se vznáší.
Tone
The lightness or darkness of a fancy coloured diamond’s colour, ranging from very light to very dark.
Saznajte višeType I / Type II
Scientific classification of diamonds based on nitrogen content and arrangement; Type I contains nitrogen, Type II is virtually nitrogen-free.
Saznajte višeUV-Vis-NIR
Ultraviolet-visible-near infrared spectroscopy, used to analyse colour origin and detect treatments in diamonds.
