Grading report
| Diamond Glossary (алмазы и бриллианты - глоссарий терминологии) |
Sometimes called a certificate, although labs do not certify diamonds. the grading report issued by an independent laboratory should accurately describe the proportions, weight, colour, clarity, symmetry, polish and fluorescence seen in the diamond being evaluated.

Proportions, английский
- Пропорции
- Relative dimensions and angles of a polished diamond and the relationships between them; these include table size, crown angle, crown height, girdle thickness, pavilion angle, pavilion depth, culet size, girdle outline, length-to-width ratio, and total depth.
Fluorescence, английский
- Emission of light of particular wavelength, as a result of absorption of light at shorter wavelength. it is a property of some materials; each material has a specific wavelength of absorption and emission.
- Luminescence arising from irradiation with light
- The emission of visible light from a substance (such as a phosphor) as the result of, and during, the absorption of radiation of shorter wavelengths.
- The sending out of light from a substance which is receiving radiation
- Certain diamonds exhibit colored luminescence (usually blue) when exposed to strong sunlight or ultraviolet light. all you need to know about diamond fluorescence.
- Emission of visible light by a material such as diamond when it is simulated by higher energy x-rays, ultraviolet radiation or other forms of radiation. fluorescence continues only as long as the material is exposed to the radiation. strong or very strong fluorescence may make a diamond appear milky or oily especially in sunlight.
- Fluorescence happens when a diamond is exposed to ultraviolet light, it may emit a soft glow of white-ish, blue-ish or yellowish light. diamond grading reports will most often note whether a diamond has fluorescence, however, is not considered a grading factor, only a characteristic of that particular diamond.
- The property by which some minerals and some organic substances, when exposed to ultra¬violet radiations, emit a light of a color differing from their own, like the blue-white light emitted by scheelite.
- Emission of electromagnetic radiation, usually as visible light, that is caused by the flow of energy into the emitting body. the emission ceases abruptly when the excitation ceases. fly: the short, waste fibers that are released into the air in textile processing operations such as picking, carding, spinning, and weaving.
- The process in which molecules or matter absorb high energy photons and then emit lower energy photons. the difference in energy causes molecular vibrations.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer wavelength). in visual testing, fluorescence is typically a response to ultraviolet radiation.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer) visible light wavelength. fluorescence in ndt may be a material’s response to ultraviolet or ionizing radiation. the emission ceases as soon as the exciting energy is removed. differs from phosphorescence, which continues to emit after excitation energy is removed.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer) visible light wavelength. fluorescence may be a material’s response to ultraviolet or ionizing radiation. the emission ceases as soon as the exciting energy is removed. differs from phosphorescence, which continues to emit after excitation energy is removed. see also spectrofluorometer.
- Luminescent phenomenon exhibited by some substances where higher energy electromagnetic waves are absorbed and reemitted as lower energy waves. the emission ceases as soon as the exciting energy is removed. different from phosphorescence, which will continue to emit after the exciting energy is removed. in magnetic particle testing, pigments coating the magnetic particles are excited by invisible uv-a radiation and emit visible light.
