GRAFICO DI CONFRONTO TRA I BRILLANTI RUSSI
SINTETICI E I DIAMANTI NATURALI:
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.

COMPARE Diamond CPG vs. CZ (ZIRCONI)
Our Diamond CPG simulant is different from a CZ in four key ways: weight, hardness, coating, and
chemical composition. 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):
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
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.

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.

b) COME VALUTARE IL NOSTRO PRODOTTO:
- LE NOSTRE PIETRE E LE 4 C;
- CZ E MOISSANITE;
- L’ARTE DEL TAGLIO DELLE PIETRE.
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.

L’ARTE DEL TAGLIO DELLE PIETRE:
A perfectly cut gemstone refracts light in a very specific way. 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.

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.

Il primo DIAMANTE di laboratorio fu prodotto nel 1902 a Parigi, Francia
da un chimico, Luigi Verneuil.
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.
Attualmente si ha in produzione
ALEXANDRITI, SMERALDI, RUBINI, E AZZURRI TIPO ZAFFIRI ED
ALTRO.
