Technology Analytical tools used at Bellerophon | Gemlab Microscope Backbones of gemmology, the microscope enables gemologists to make an diagnostic regarding the genesis, absence, or indications of treatments, and origin determinations, by studying the inclusions under high magnification. -Genesis -Treatment detection -Origin determination Digital Microscope The digital microscope enables gemologist to study a gemstone from anywhere in the world, and magnification power is greatly increased from a regular microscope, our Keyences VHX6000 enable us to observe inside a gemstone at 5,000x magnification. Refractometer The refractometer measures the extent of light refraction, as light passes through the gemstone from the air it will slow down and create refraction, the severity of the refraction will depend on the mineral composition, very useful information for identification. -Identification Specific gravity Specific Gravity (SG) is the ratio of the weight of a substance to the weight of an equal volume of water. It measures the density of a mineral, based on the earth's gravity, which depends on the chemical composition and crystal structure of a gemstone, very valuable information for identification. -Identification Polariscope The polariscope enables us to distinguish between isotropic and anisotropic transparent minerals. -Identification Fourier Transform Infrared Spectroscopy The FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. Bellerophon uses it to obtain an infrared spectrum of absorption of a gemstone, Extremely important information for identification, treatments detection, and genesis. -Identification -Genesis of emerald for exemple -Treatment detection such as low heat in corundum -Origin determination Raman Spectroscopy & Micro Spectrometry Raman spectroscopy provides a structural fingerprint by which molecules can be identified. Raman spectroscopy relies upon the inelastic scattering of photons, knowns as Raman scattering. A source of monochromatic light, laser of 532nm, or 785nm interacts with molecular vibrations, phonons, or other excitations in the system, resulting in the energy of the laser photons being shifted up or down. The shift in energy gives information about the vibrational modes in the system. -Identification -Genesis of Quartz for exemple -Treatment detection such as oil and resin -Origin determination Photoluminescence Spectroscopy Photoluminescence spectroscopy, abbreviated as PL and the laser used such as PL313, PL532 is light emission from a gemstone after the absorption of photons. it is one of many forms of luminescence and is initiated by photoexcitation (photons that excite electrons to a higher energy level in an atom). -Identification -Genesis of Spinel for example -Treatment detection Energy-dispersive X-ray fluorescence In EDXRF spectroscopy, all of the elements in the gemstone are excited simultaneously, and an energy dispersive detector in combination with a multi-channel analyzer is used to simultaneously collect the fluorescence radiation emitted from the sample and then separate the different energies of the characteristic radiation from each of the different elements. it enables gemologists to know and quantify (semi-quantitatively) all elements present in samples from Sodium (Na) to Uranium (U). -Genesis of corundum for example -Treatment detection such as lead glass -Origin determination Laser-Induced Breakdown Spectroscopy Laser-induced breakdown spectroscopy (LIBS) is atomic emission spectroscopy that uses a high-energy laser pulse as the excitation source. The laser is focused to form a plasma, which atomizes and excites a small part of the gemstone. Laser-induced breakdown spectroscopy (LIBS) is considered as a quasi non destructive testing due to the fact that the laser ablate a microscopic part of your gemstone, creating an approx ~0.20 mm hole. -Treatment detection for Beryllium diffusion in corundum -Origin determination of emerald Ultraviolet-visible near-infrared spectroscopy UV-vis refers to the absorption in part of the ultraviolet and the full visible regions of the electromagnetic spectrum. It uses light in the visible range. The absorption in the visible range directly affects the perceived colour of the elements involved (chromophores). -Origin determination Ultraviolet and Visible Spectrophotometry and Imaging Spectrophotometry is a branch of electromagnetic spectroscopy concerned with the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. The absorption of light is due to the interaction of light with the electronic and vibrational modes of molecules. Each type of molecule has an individual set of energy levels associated with the makeup of its chemical bonds and nuclei and thus will absorb light of specific wavelengths, or energies, resulting in unique spectral properties. This is based upon its specific and distinct makeup. -Origin determination -Genesis -Colour Grading -Treatments Visit Bellerophon Colour Grading >

Discover the Royal blue Sapphire trade name colour description, provenance and science behind. Decouvrez la description du saphir couleur bleu royal. ROYAL BLUE Sapphire Provenance The name "royal blue" appeared between 1810 and 1820. The "royal" in the name comes from the British royalty, where this shade of blue is said to have been created by a tailor in a competition to make a dress for Queen Charlotte in the early 19th century. The blue associated with royal blue has actually changed over time. Prior to the 1950s, the original royal blue was considered much deeper than the official one approved in the 1980s by the World Wide Web Consortium, which associated the now lighter blue, along with its RGB code, with the name "Royal blue". The original royal blue appears on the flag of the United Kingdom and is the colour closest to that used today for royal blue sapphire. Royal Blue describes the sapphire with the most vivid and deepest saturation. It was probably first used by British gem trader to describe sapphire when Ceylon (now Sri Lanka) and Burma (now Myanmar) was part of the British Empire. The symbolism of royal blue includes tranquility, as blue is the colour of the sky and the ocean, both of which are known to promote feelings of peace. The colour blue is synonymous with significance, importance and confidence. This is where the blue corporate suit and the blue uniforms around the world come from. Definition Colour has the greatest influence on the value of a sapphire. Royal blue describes sapphires with a pure blue to very slightly violetish blue hue, with a vivid saturation, which can in rare cases range from intense to deep, the tones should be medium to medium dark. For more information on colour classification, see here . Clarity has a very important influence on the value of a sapphire. Royal blue sapphire must be flawless, preferably clean to the eye, or at least transparent, without pronounced inclusions that are very visible under the table. The colour uniformity must be excellent or evenly distributed. Cut plays a very important role in the colour of a sapphire. Royal blue sapphires should have excellent to good proportions to maximise total internal reflection. Royal blue sapphires should not show significant windowing (transparent area) and/or extinction when viewed face up. Treatment of Royal blue sapphire is acceptable only for no treatment or traditional heating. Therefore, any other treatment such as diffusion of foreign ions into the sapphire lattice, like beryllium or titanium, fracture sealing with resin, or lead, cobalt and/or silicate glass, will not be granted a gemmological report and as such not qualified for Royal blue or any other colour grading. Blue sapphire master set. Reference collection Bellerophon Gemlab. Science The classification of the colour of a gemstone is both an art and a science. The adjective "Royal blue" combines many facts about a sapphire. Classifying the colour of a transparent anisotropic material like a blue sapphire is not as simple as it sounds. The hue, saturation and tones must fall within a predetermined range for the sapphire to be considered "royal blue". The blue colour of sapphire is the result of a major chromophore: iron with titanium in pairs. It replaces some of the aluminium atoms in the structure, the more iron and titanium pairs, the bluer the sapphire all the way to black. The approximate iron and titanium content in most blue sapphire is between one to couples of tens of pairs of atom per million. Two other chromophores almost always play a role in blue sapphire: iron and chromium. The iron content tends to make the sapphire green, decreasing the blue saturation and increasing its tone, while chromium makes the sapphire violetish. Quantifying the chromophores present in a sapphire provides a good starting point for colour comparison without the influence of other factors such as the path of light through the stone and reflections. By combining this method with the overall proportions of the stone, we can analyse the most influential colour factors separately and compare them to our reference collection of "Royal blue" sapphires.

Holding our world in trust to our children. Bellerophon gemlab address head on the challenges of gemstone report CO2 emission and work toward reducing it further. NEWS & ARTICLES Bellerophon | Gemlab Environment Holding our world in trust to our children -Michael Meacher Our commitment to becoming carbon neutral drives a lot of what we do. Every Bellerophon Gemlab Reports will be made with clean energy and even more recycled and renewable materials. Bellerophon Gemlab Carbon footprint Bellerophon Gemlab reports are partly made of recycled paper and recycled plastic. We are committed in increasing every year the percentage of recycled products as well as reducing our greenhouse gas emission within our laboratories. The Carbon Footprint is an estimation of the carbon emitted into the atmosphere over a year by the activities of an organization. It is used to identify the main emission sources and to initiate a process to reduce these emissions. The article 75 of the law n° 2010-788 of July 12, 2010 concerning the national French commitment for the environment (ENE) has established the principle of a generalization of the greenhouse gas emission assessments (GHG assessments) for many public and private actors. Bellerophon Gemlab is not submitted to this legislation, we carries out this carbon footprint in a transparent way towards you because we are committed to reducing our greenhouse gas emissions in a sustainable way. Maximum Carbon emissions per service. The methodological guides presented by the French Agency for Ecological Transition (ADEME) were used to carry out this carbon assessment. This method takes into account the direct or indirect greenhouse gas emissions produced by the company. The accounting method we used is the calculation of emissions. To summarise the greenhouse gas emissions, the emission flows are multiplied by emission factors. This makes it possible to calculate the quantity of pollutants emitted in carbon equivalent. GHG distribution per laboratory In 2022, Bellerophon Gemlab emitted 1.3 times less greenhouse gas emissions than the average French company of the same size. The energy used in the laboratories represents a significant part of our greenhouse gas emissions. With the opening of a second laboratory, the activity of Bellerophon laboratories has become more international, resulting in an increase in employee travel. Bellerophon Gemlab greenhouse gas emissions was collected using the methodological guides presented by the French Agency for Ecological Transition (ADEME) for the years 2021 and 2022 by Maximilien Rozet.
