You are Welcome!
My name is Alessandro Greco and I'm Polished diamond certified at I.G.I. Antwerp (International Gemological Institute).
I'm new in e-bay, but hope to satisfy You analizing also very little stones, to give you all the information you need to know how to buy
the most beautiful and precious stones in the world!
Before you start looking for a diamond, you want to have all of the necessary information that is available to you, because the more you know, the better prepared you are to make decisions regarding your purchase.
"LEARN ABOUT THE FOUR C's: CUT, COLOR, CLARITY, CARAT.
Most diamonds are cut round with a full 58 facets, and a good cut, or make, has more scintillation, more sparkle. It is the work of a master cutter that allows the diamond to be cut in such a way as to permit the maximum amount of light to be reflected through the diamond, and that's a great reflection on you. It is the cut that enables a diamond to make the best use of light.
The most common diamond color is yellow. Most diamonds have a slight hint of yellow and the diamond color scale is based on the amount of yellow present in a diamond. Diamond color is graded according to the GIA Grading Scale. Grades are based on the amount of yellow that is visible when viewed facedown through the pavilion on a white diamond color card using daylight equivalent fluorescent light. Each color grade is based on a very small range. When a diamond is color graded it is compared using a set of master stones. Master stones are a set of real diamonds that display a range of known colors. It is extremely difficult to see the color differences within diamonds, but master stones help graders distinguish between one color and the next.
GIA color-grading scale
As you can see the color-grading scale ranges from D to Z. The highest color grade and whitest stone available is a D color diamond. This is also the rarest color grade, which translates to a higher value. Colors E and F have no detectable color to the naked eye and they fall into the Colorless category. Diamonds in the G to J color range have a hint of body color and are considered Near Colorless. The eye begins to detect faint traces of yellow in diamonds that are in the J to M range. Diamond Ideals typically sells diamonds in the color range of D to J and occasionally K.
The AGSL uses a slightly different color grading scale. The AGSL ranks the stones from 0-10, in 0.5 increments with 0 representing the equivalent of colorless D stones, and 10 representing the equivalent of X, Y and Z colored diamonds.
Ideal Cut Diamonds Can Mask Subtle Color Differences:
Ideal Cut diamonds offer a little flexibility in color selection. Because Ideal Cut diamonds are designed to maximize brilliance and scintillation they also tend to mask subtle color differences making H and I color diamonds appear beautifully white. Ideal Cut H and I color diamonds tend to appear whiter than poorly cut diamonds of the same color.
Color can save you money
A diamond's color grade does not pertain to the "face-up" look of a particular diamond, but rather to the "body" color of the material. The best way to assess diamond color is to view it from the side, un-mounted, against a white background, using a daylight fluorescent bulb.
An AGS Triple Ideal Cut Hearts & Arrows diamond reflects more than 99% of the light back through the crown. There is virtually no light leakage in these stones. What this means to you is that rather than seeing the diamond's color, when you look at a Hearts & Arrows diamond, all you see is white light and scintillation. These diamonds appear whiter than non-Ideal diamonds. Keep this in mind if budget is an issue. By dropping one color grade in an AGS Triple Ideal Cut Hearts & Arrows diamond, you will not be giving up anything in the look of your diamond and you will be saving money.
The diamond's clarity is a description of its internal purity. With fewer imperfections within the stone, the diamond is more rare and has a higher value. The clarity scale was developed by the Gemological Institute of America (GIA) to quantify these imperfections. The American Gem Society (AGS) uses the same standards as the GIA; however, the AGS uses a numerical system where "0" is the cleanest (GIA "IF") and "10" is the most imperfect (GIA "I3").
All diamonds are systematically graded and plotted under 10X magnification. If a trained grader cannot see a clarity characteristic at 10X, it does not affect the clarity grade.
Five Factors That Determine Clarity:
All of the above factors are taken into consideration when a diamond is assigned a clarity grade.
Clarity Grades Defined by the GIA:
Flawless — Flawless diamonds have no inclusions or blemishes when viewed under 10X magnification by a skilled grader. A diamond can have naturals confined to the width of the girdle, extra facets on the pavilion that are not visible face-up, laser inscriptions confined to the girdle and internal graining that is not white, colored or reflective.
Internally Flawless (IF) — An IF diamond has no inclusions, only blemishes when viewed under 10X magnification.
Very Very Slightly Included (VVS1 and VVS2) — VVS diamonds contain minute inclusions that are difficult for a skilled grader to see under 10X magnification. The inclusion in a VVS1 diamond are extremely difficult to see face-up, or may be visible only through the pavilion. Inclusions in a VVS2 diamond are very difficult to see. Typically VVS diamonds have a pinpoint or two; however, characteristics like a bearded girdle or tiny chips might also be present in VVS diamonds depending on their visibility.
Very Slightly Included (VS1 and VS2) — Diamonds of VS clarity contain minor inclusions that range from difficult (VS1) to somewhat easy (VS2) to see under 10X magnification. Typical inclusions in VS diamonds include small crystals, feathers and distinct groups of pinpoints.
Slightly Included (SI1 and SI2) — Diamonds of SI clarity contain noticeable inclusions that are easy (SI1) or very easy (SI2) to see under 10X magnification. Typical inclusions, such as crystals, clusters of pinpoints and feathers, are centrally located.
Included (I1, I2, and I3) — Diamonds in the 'I' clarity range contain inclusions that are obvious under 10X magnification. These inclusions can often times be seen face-up without magnification, sometimes affect the stone's durability and can be so numerous or large that they affect transparency and brilliance.
The clarity is typically assigned by a first impression or at first glance. The grader notes whether the inclusions are easy, difficult or very difficult to see when they first look at the stone. The clarity grade of most diamonds is determined in less than 2 minutes. The exception to this is in Internally Flawless and Flawless diamonds, which take considerable examination to assign such a high and valuable grade. It of course takes longer to plot included diamonds as well.
Clarity Grading Scale
What is Eye-Clean:
"Eye-clean" is a term used to describe a diamond or an inclusion that is not visible to the unaided eye when the diamond is held face-up (viewed through the table) at a normal viewing distance of 10 to 12 inches. Nearly all VS clarity diamonds are eye-clean, most SI1 clarity diamonds are eye-clean and some SI2 and even I1 clarity diamonds are eye-clean.
An inclusion is called "eye-visible" when it is visible to the unaided eye, without magnification.
Types of Clarity Characteristics:
There are two basic categories of clarity characteristics, inclusions and blemishes.
Inclusions are clarity characteristics that are completely enclosed in a polished gem or those extending into it from the surface. Examples of inclusions are as follows:
Crystal — Another mineral crystal contained in the diamond. These crystals can include other diamonds, garnet or a host of other minerals.
Needle — A long, thin crystal.
Pinpoint — A very tiny crystal that looks like a dot or speck of dust. Pinpoints often congregate in clusters or clouds.
Twinning wisp — A series of pinpoints, clusters or crystals that formed in a twinned diamond's growth plane.
Internal graining — The appearance of faint lines, angles or curves caused by crystal growth.
Feather or gletz — A general term for any break or fracture in a diamond.
Bearded girdle — Minute feathers that extend from the girdle surface into the stone.
Indented Natural — The original crystal surface, or skin, that dips below the polished diamond's surface.
Knot — An included diamond crystal that extends to the surface after polishing.
Cavity — Space left when a surface-reaching crystal comes out during polishing.
Blemishes are external clarity characteristics caused by wear, the cutting process or the diamonds crystal structure. Examples of blemishes are as follows:
Nick — A small chip-like characteristic.
Abrasion — A series of minute nicks along a facet junction.
Scratch — A thin, dull, white line across the diamond's surface.
Natural — A portion of the original skin that remains on the diamond.
Pit — Small surface characteristic that looks like a tiny dot.
A Note on Clarity Enhancement:
Diamond Ideals does not sell any clarity-enhanced diamonds.
Clarity enhancement is a treatment to improve a diamond's apparent clarity. A diamond with eye-visible inclusions can be seen as less desirable. To make the diamond more desirable and marketable, some sales people have the diamond clarity enhanced to make the eye-visible inclusions less visible or invisible to the naked eye.
There are two common types of clarity enhancement. The first type of clarity enhancement is called laser drilling. Laser drilling is the use of a laser to drill a small hole in the diamond, extending to reach a visible inclusion such as a black crystal. Sometimes an acid is used to bleach or dissolve the included color, improving its appearance. Laser drill holes can typically be seen as tube like inclusions in the diamond when viewed perpendicular to the point of entry under 10X magnification. The hole can also be seen as a tiny pit-like blemish on the surface, under reflective light of a microscope.
The second type of clarity enhancement is fracture filling. Fracture filling involves the use of a molten glass substance to fill or mask the reflective qualities of an internal fracture. Fracture filling can be detected by the telltale 'flash effect' that the filling produced. The flash effect can be seen as two distinctly different colors that appear when you rock and tilt the diamond in different directions. Some untreated feathers can show an iridescent rainbow of colors from all directions, so it is important to know the differences.
Fracture filling is not a permanent treatment and therefore GIA does not grade fracture filled diamonds. GIA does, however, grade the permanent laser drilled diamonds.
Again, Diamond Ideals does not sell any clarity-enhanced diamonds.
A carat is a weight measuring unit equal to 0.2 grams. It is the internationally used unit to measure the weight of diamonds. Within the diamond trade, fractions of a carat are referred to as "points" or simply as fractions. A 50-point diamond weighs 0.5 carats or 1/2 a carat. A 1-carat diamond weighs 100 points. A 1/3 is also 0.3 carats or 30 points.
As nature would have it, rough diamonds come in all shapes and sizes, as well as colors and purities. The larger, whiter and cleaner the diamond, the more rare it is. Accordingly, the cost per carat of a larger diamond of the same color, clarity and cut will be higher than a smaller diamond. The price per carat of diamonds rises proportionately with size. Keep in mind that the per carat price gets multiplied by the carat weight.
More weight equals more money so, many diamond cutters sacrifice brilliance to maximize carat weight and profit. It is important to realize that weight does not always equal size or beauty. Poorly cut diamonds intended to maximize size can be dull and lifeless. Some experienced cutters sacrifice weight and focus on cut to obtain the most beautiful and brilliant Hearts and Arrows diamonds on the market today. On the average, cutting a Hearts and Arrows Ideal Cut Diamond requires a 15% greater waste of the original material. The added beauty one obtains from a Hearts and Arrows diamond is well worth the sacrifice. Diamond Ideals specializes in sourcing these cutters and bringing the most beautiful diamonds to you."
