Even larger sizes are available by custom order. The 4 Cs Comparison Charts classic particular gems - Salvatore Profeta – International broker – GRAFICO DI CONFRONTO TRA I BRILLANTI RUSSI SINTETICI E I DIAMANTI NATURALI: classic particular gems - Salvatore Profeta – International broker – What are Certified Signature Series Stones? Our Certified Signature Series® simulants represent a new achievement and the utmost perfection in diamond simulant creation. The Certified Signature Series simulants are subjected to incredibly rigorous standards resulting in extraordinary precision and quality. Every step of the process is monitored by discerning eyes. Each piece is hand-picked and matched. These processes are so exacting that when they are finished, each simulant is laser inscribed with a unique Maker's Mark serving as the stone designer and cutter's personal signature and certification that the simulant is absolutely ideal in every aspect. Each Certified Signature Series® simulant, either purchased individually or mounted as a focal piece in our jewelry, will arrive with an American International Gemologists (AIG) Certification and Diamond Simulant Grading Report documenting the exact specifications and characteristics of your individual piece. All Certified Signature Series® simulants can be custom laser inscribed with whatever information you desire: names, dates, a favorite quote or memory... only your imagination is the limit. Previously only mined diamonds from the most prestigious jewelry houses, such as Cartier, Tiffany and Harry Winston offered personal diamond inscribing, and then only on their custom, multi-carat showpieces. Your inscription will not affect the brilliance of your Diamond CPG diamond simulant, and will only be visible under magnification.* When you gaze into the depths of your beautiful, sparkling diamond simulant, only you and your love will know that a private message is reflected in each brilliant facet. With every personally inscribed simulant you will receive an enlarged image of your inscription which will clearly show your personal and everlasting message. All loose Certified Signature Series® simulants or jewelry set with Certified Signature Series® simulants take 8-9 business days to ship.

These differences result in a superior Diamond CPG simulant with qualities much closer to that of a mined diamond. Weight Our Diamond CPG simulant weighs 15% to 20% more than a CZ of the same size. Hardness Our Diamond CPG simulant is very hard. The chemical composition of CZ makes it a softer, more porous stone. For example: over time, as you wear a CZ, it will absorb the oils in your skin, the soap you use to wash your hands, etc... Eventually, the CZ will appear yellowish and lose its fire and ability to disperse light. Due to the softness of the stone, its facets will also wear down with use. A Diamond CPG simulant is closer to the properties of a mined diamond. As such, it will not chip, fade, or lose its brilliance over time. Coating A lot of companies sell a common CZ and put a coating on their product as a way to differentiate it. Sometimes the language used is "diamond infused", "diamond hybrid" or "sealed in a diamond". The coating they are referring to is called "DLC", which means "diamond-like coating". This coating process has been around for years, and the "diamond" coating being referred to is "amorphous carbon" which is really pencil lead. When a stone is coated with amorphous carbon, the coating must be exceedingly thin as to be essentially non-existent. Otherwise, the stone would be discolored. At Diamond CPG, we also have a coating on our simulants. Our coating material is Corundum and other proprietary materials which is substantial, visible under microscopy, and has important measurable physical characteristics. The coating seals the simulant's surface, greatly lowers porosity, and makes the simulant impervious to outside contaminants. It also increases the hardness and the ability of the simulant to resist scratches. Here you can see an example of our coating which depicts its thickness at 131.2nm, over 10,000 times thicker than our competitors. Chemical Composition CZ or cubic zirconia is made of zirconium oxide and sometimes a yttrium stabilizer. Diamond CPG simulants are comprosed of (in order of atomic weight): classic particular gems - Salvatore Profeta – International broker – Carbon (C) Sulfur (S) Iron (Fe) Calcium (Ca) Cobalt (Co) Nickel (Ni) Yttrium (Y) Zirconium (Zr) Gadolinium (Gd) Hafnium (Hf) Diamond CPG vs. Moissanite Below you will see two charts from an independent lab report which show a spectrographic analysis for CZ and for our product. A spectrographic analysis is an analysis which uses a spectroscope (an optical device for producing and observing a spectrum of light or radiation from any source) to determine the chemical elements in a source by measurement of the wavelength and spectral line intensity produced by any one of several methods of excitation such as arc, flame, infrared and X-ray. As you can see from the data, our simulants are not Cubic Zirconia. We have gone to great lengths to create a simulant that is nearly the same physically and optically to a mined diamond. The difference is in the chemistry-and that exact formula is proprietary. How is our Diamond CPG simulant different from Moissanite? Our Diamond CPG simulant is different from Moissanite in much the same way that a diamond is different from Moissanite. While Moissanite is beautiful in its own right, it does not function chemically or optically like a diamond or a Diamond CPG simulant. Chemically, it is silcon carbide. Unlike a diamond or our simulant, moissanite is strongly birefringent or doubly refractive. This is a desirable quality in some optical applications, but is not desirable in gemstones. For this reason, Moissanite jewels are cut along the optic axis of the crystal to minimize birefringent effects. Moissanite's higher index of refraction (brilliance) and much greater dispersion (fire) than either a diamond or Diamond CPG classic particular gems - Salvatore Profeta – International broker – simulant make it easy with the naked eye to distinguish a Moissanite from our stone and from a diamond. Finally, where the best quality diamonds and Diamond CPG simulant have a D color (meaning virtually colorless), a moissanite stone has a slight green tint to it that becomes more noticeable with increasing carat sizes. > Property Diamond Diamond CPGMoissanite Brilliance 7.40 7.40 8.90 Dispersion 0.44 0.46 1.01 Refraction 2.40 2.20 2.68 Refraction Type Isometric Isometric Hexagonal Crystal System Single Single Double Birefringence No No Yes Luster Adamantine Adamantine Viteous Fracture Conchoidal Conchoidal Conchoidal Color Streak Colorless Grey/Green Colorless Rubies, Emeralds, Sapphires Bold, deep, and passionate: the rich intoxicating colors of rubies, emeralds, and sapphires have enchanted countless civilizations for millennia. Symbols of love, royalty, vitality, and mystery, these precious gemstones in their most exceptional form are rarer than diamonds and valued at thousands of dollars per carat. Our laboratory-grown rubies, emeralds, and sapphires are perfectly identical to their mined counterparts: physically, optically, and chemically. They don't just look like the real thing; they are the real thing.

Chances are you already know a lot about diamonds. Diamonds are generally evaluated by assessing the 4 Cs: Clarity, Color, Cut, and Carat Weight. Clarity Clarity describes the purity of a diamond. This is determined by the number, size, nature, and location of the internal inclusions and external imperfections. The highest purity rating attainable is IF (internally flawless). All of our simulants and synthetic stones are IF rated. Color Color describes the amount of color a diamond contains. The color scale ranges from absolutely colorless (D color) which is the most preferred, all the way down to colors that can be quite gray and muddy looking. In addition to white stones, diamonds can come in some pretty intense colors called "fancy colors" which may be yellow, red, pink, blue, and even green. But when most people think of a diamond, they are thinking of the traditional white diamond. All of our simulants, with the exception of our fancy color simulants, are D color. Cut Cut speaks to the way a diamond's proportions are created. It is really quite mathematical. A perfectly cut diamond will yield the most fire and brilliance. In the jewelry industry, there is an ideal cut formula which was first developed by Marcel Tolkowsky, a Belgian diamond cutter and engineer who in 1919 developed this optimal cut to bring out the most fire in a diamond. All of our simulants and synthetic stones are cut to the same standards and exacting measurements first developed by Marcel Tolkowsky. Carat Carat is the unit of weight for a diamond. In nature, large diamonds are much rarer than small ones, so they will come with a much higher price tag. A three carat stone may be priced as high as twenty times the price of a one carat stone. Diamond Lab creates are not subject to this issue of size scarcity: all of our simulants and synthetic stones carry the same per-carat price. classic particular gems - Salvatore Profeta – International broker – How is our DLC simulant different from CZ? Coating: A lot of companies sell a common CZ and put a coating on their product as a way to differentiate it.

If the faceting angles and transitions exactly match the Ideal Cut Formula, first set down by Marcel Tolkowsky in 1919, the stone will refract a dazzling pattern when viewed under a diamond scope: "Hearts and Arrows" for a Round Cut and 'Starred Cross" for a Princess Cut. In the diamond world, less than 15% of all diamonds reach the Ideal Cut Standard. That is why true "Hearts and Arrows" diamonds are priced at such an incredible premium. At LAB CREATED DIAMOND, all of our simulants and synthetic stones achieve the Ideal Cut Standard and will display flawless Hearts and Arrows and Starred Cross patterns. We simply cannot call ourselves strivers for perfection and offer anything less. "Starred Cross" pattern executed in every Princess Cut simulant. Eight-Point Hearts & Arrows Pattern captured in every Round Brilliant Diamond LAB CREATED classic particular gems - Salvatore Profeta – International broker – 3) TERZA PARTE c) IL PROCESSO DI FABBRICAZIONE LCD's products, which include diamond simulants as well as synthetic rubies, emeralds, and sapphires, have only become possible in the last few years due to significant breakthroughs in chemical and materials engineering. This section of our site will take you through the creation process of our products step-by-step, and will also teach you how DIAMOND LAB CREATED compares with other products available today. Our leading product, the DIAMOND LAB CREATED, is a revolutionary coated crystal that near perfectly recreates the optical and physical (how it looks and how it wears) properties of an earth-mined diamond. The patent-pending process to create this simulant is complex, but ultimately worthwhile. Significantly different from and superior to other competing products such as CZ and Moissanite (learn more), a DIAMOND LAB CREATED will cut glass, is incredibly hard, and, like an earth-mined diamond, will last forever. No one in the world, including your jeweler, can tell that a DIAMOND LAB CREATED is not a natural diamond without scientific testing. The Simulant Creation Process: Your DIAMOND LAB CREATED begins its life in a ceramic and carbon-fiber crucible, which is lined with a very technologically advanced phase-change material that is necessary to handle the enormous heat and pressure of the simulant creation process. At extreme temperatures, approaching 4000 degrees, we mix a proprietary blend of elements in a very specific sequence and we bring them to a molten state called a "matrix". Highly specialized equipment is required, as the matrix is so hot it will destroy most containment mediums. classic particular gems - Salvatore Profeta – International broker – Qui di seguito la tabella comparativa, riconosciuta a livello internazionale: Russian LAB C&C Moissanite Diamond Natural CPG/ Carat CZ Color D-E J-K (tint) D-E Unknown New Clarity Flawless VS2+ Flawless Unknown New Cut By Hand By Hand By Hand Unknown Cuts Glass Yes Yes Yes Basic CZ?

Un gemstone che è creato in un laboratorio non è contraffatto o artificiale, ma è un cristallizzato attentamente col tempo. Essenzialmente ha le stesse proprietà ottiche, fisiche e chimiche come un naturale DIAMANTE . Solo un’attenta analisi gemmologica qualificata può riconoscerlo.. I DIAMANTI NATURALI sono cristalli formati da calore e pressione all'interno della terra. Un calore simile e l'ambiente di pressione è creato nel laboratorio che usa gli stessi naturali elementi. Questo processo impiega DAI 10 a 14 mesi per completarsi.
