Everyone Wants Big Diamonds

By: David Cowley

As a status symbol big diamonds have no equal. It shows that you have the ability to spend an extravagant amount of money on jewelry. When not being displayed these beautiful gems are hidden away in secure locations and rarely see the light of day. When was the last time you have seen the Esther Williams famous Champagne diamond ring or the Taylor Burton pear shaped diamond?

Finding a good jeweler is the first step you need to take when purchasing any jewelry item. It is also necessary to do some research on the grading system of diamonds. Many good article are available on the internet to assist you in understanding the 4 C's of diamond grading. After you have learned the fundamentals your jeweler can clarify your understanding.

The American Gem Society (AGS), the Gemological Institute of America (GIA), and the International Gemological Institute (IGI) are the three most widely known and respected diamond grading laboratories in the world and each of them has developed a very similar nomenclature for identifying the 4 C's of diamonds. The 4 C's stand for Carat, Color, Clarity, Cut and I like to add shape to the 4 C's list.

The first of the 4 C's is the Carat. A carat is 0.2 grams or 200 milligrams and is always referenced within 2 decimal points. For example the the Golden Jubilee is considered the largest faceted diamond in the world and weighs in at 545.67 carts. The Taylor-Burton diamond is 69.42 carats. This is a highly accurate grading scale used to determine the weight or size of a diamond but it does not apply a value to the diamond.

Color Grading D to Z

The next thing you need to look at when purchasing a diamond is the color of the diamond. A white diamond is not white but clear in color. Different colors in diamonds are produced because of impurities trapped in the diamond during the formation process. Since nature rarely create anything pure many diamond will have show some color to the naked eye. Color range from totally colorless (D) to a pale color (Z). Diamonds of a higher grade than (Z) fall into the fancy color diamond range. A diamond with a color range greater that (K) usually have a descriptive phrase such as grade (M) Faint Brown.

White diamonds are usually more expensive because of their rarity, D through F, but some diamonds in the fancy color range can command a very high per-caret price. Pink diamonds have sold for up to $1,000,000 a carat. The largest Fancy Vivid Pink diamond is the The Steinmetz Pink Diamond and is 59.60 carats in weight.

Clarity Grading is the third factor in determining the quality of a diamond. This grading requires education and years of practice for a gemologists to master. The number and nature of the defects in a diamond is taken into account when applying the clarity grading code. Basically the diamond is looked at with the naked eye and under a 10X magnification lens.

Internally Flawless (I.F) when it presents no internal defects under 10x magnification.

Very slightly included (V.V.S.1 to V.V.S.2) when it presents defects that are very difficult to locate under 10x magnification.

Slightly Included (S.I.1 to S.I.2) when it presents defects that are easy to locate under 10x magnification.

Imperfect (P.1 to I.1) when it presents defects that are hard to locate with the naked eye.

Imperfect (P.2 to I.2) when it presents defects that are easy to locate with the naked eye.

Imperfect (P.3 to I.3) when it presents defects that are very easy to locate with the naked eye.

Next is the cut of the diamond and the cut has nothing to do with the shape of the diamond. The proportions and symmetry of the diamond cut determines the light dispersion, brilliance or life of the diamond. If the diamond's reflective qualities are below standard then the appearance of the diamond will be adversely affected. Many of the diamond cut over a couple hundred years ago were cut to maximize the carat weight with little regard to the diamond's reflective qualities. Many of the older stones have been recut to increase its brilliance. A good cut give the diamond it brilliance or the ability to handle light in a pleasing fashion. The brightness will seem to come from the very heart of a diamond.

American Star

In 2001 the EightStar company of California wanted to prove that optical perfection of the round brilliant diamonds could be obtained by using an exclusive light-tracking instrument called a FireScope which allows a diamond cutter to align facets so precisely that the flow of light into and out of a diamonds can be completely controlled. The American Star as slowly cut from 14.89 to 13.42 carats over a six-week period. Cutting the diamond for maximum light output and not size increased the beauty of the American Star and many of the older diamonds have gone through a recut.

There are several standard categories for the shape of the diamond but there are many variations on each standard categories. Basic categories include Round, Emerald, Pear, Heart, Marquise, Oval, and Princess cuts.

The final shape of the raw diamond us usually determined by the imperfections found in the diamond. Many imperfections can be remove or hidden by and experienced jeweler in mounting the diamond in the final jewelry piece and by the proper cut of the diamond.

Lab-Created Diamonds – Simulated Diamonds And Manufactured Diamonds Review

There has been a great deal discussion about lab-created diamonds. Along with that talk, there is much misinformation and perplexity. The jewelry lover, who is interested in realizing the huge savings and aesthetic beauty that simulated diamonds offer, is often bewildered by the manufactured diamond industry jargon and available options. This article will categorically break it down in easy-to-understand terms so that anyone can make an intelligent decision when choosing a simulated diamond.

GEM MATERIALS: 99% of all lab-created diamonds sold worldwide are polycrystalline on a molecular level. The differences are fundamentally in the technical aspects of manufacturing, cutting, and polishing. Think of it this way—all coffeemakers are made of plastic, steel, and glass, the differences are how these materials are designed and implemented. Higher quality coffeemakers make a better tasting cup of coffee. Higher quality manufactured diamonds are in line with mined diamonds.

QUALITY VARIANCES: It seems like grade variations are made out to be a more complex lab-created diamond issue then it really is. Once boiled down, there are three primary grades of simulated diamonds—high, medium, and low. For the jewelry shopper it should be noted that the quality of setting goes hand-in-hand with the quality of the gemstone. Those that sell manufactured diamond jewelry off point-of-purchase displays in the costume jewelry sections of discount stores use low quality or scrap stones that are not gem quality, and have disco ball or murky look. Those that sell manufactured diamond jewelry on the TV shopping channels—which is generally with a sterling silver or a micro-thin layer of gold plated over silver (Vermeil [pronounced ver-may]) settings—use medium quality stones not of gem quality. Those that sell solid 14K gold or solid platinum settings, as a rule, use the highest gem-quality man made gemstones that replicate mined diamonds.

PRICING: Low grade stones are sold in bulk to costume jewelry makers and are often glued on electroplated settings. This jewelry is fine for children, where loss risk is high, and usually retails for less than $15 per item. You will find medium grade stones primarily in sterling silver jewelry that sells for under $100 per item, settings and stones. Medium grade simulated diamonds can be distinguished by the naked eye as not being mined diamonds. High grade gemstone quality lab-created diamonds, undistinguishable by the naked eye from mined diamonds, are found mounted on settings of solid 14K gold and platinum. This is considered to be fine jewelry, with the best quality gemstones selling for under $100 per carat for the gemstones alone. Manufactured diamonds that sell for over $100 a carat are not higher quality than those that sell for between $80 and $100 per carat.

RECOMMENDATIONS: If you are buying for someone that is likely to lose the jewelry, there is no reason to spend any more than you have to, and Wal-Mart will do just fine. On the clearance rack you can even pick up some jewelry for less than $5 per item. If you buy simulated diamonds set in sterling silver, expect decent stones, but they will fool few into thinking they are mined diamonds. Also, your fingers are likely to turn green or black in response to a chemical reaction, not with the silver per se, but with the nickel/copper alloys in sterling silver. With any plated settings, gemstones are low to medium grade, and the plating will eventually chip off, particularly around the edges. When that happens, the nickel/copper alloys will be exposed, the setting will look like it came out of a gum ball machine, and your finger will generally turn green or black. It is just a matter of common sense, if you want simulated diamonds with mined-diamond qualities, they must be set in 14K solid gold. Jewelers who offer lab-created diamonds are not going spend on money on gold and not mount the highest quality stones, which would defeat the purpose of creating fine diamond-like jewelry and alienate customers.

Some Guide So As To Find Beautiful And Good Diamond.

By: Nancy Jason

As you know , wedding is considered a important and happy event in our life .In the wedding day, the ring is an important thing, so people want to choose the best one for darling. Now, there are many kinds of the diamond. Like as anything else, diamonds come in a wide variety of shapes and sizes, a wide variety of prices. So you should careful seach and fully understand before decide to buy. The very first step in this process is to find wholesale dealers who specialize in loose diamonds, where you have the best chance of them being able to offer you the perfect diamond stone. There are a wide variety of diamond and precious gem wholesale dealers out there, so you want to first make sure that the loose diamonds wholesale supply is filled with a wide choice of quality gemstones.

When looking at diamonds in particular, remember the “four Cs” of diamond selection – Cut, Clarity, Color, and Carat. The diamond should be clear and sparkling with a small hint of reflective color. The diamond cut must be very precise and clean without rough edges. Don’t be afraid to ask for a magnifying glass, or if you really want to look like you know what you are doing, ask to borrow their “loop”, which is the name of the small monocle microscope used by quality jewelers. Take the time to look at your potential selection closely and from various angles to make sure you detect any flaws that might be present in the stone. Loose diamonds come in many different cuts from the diamond wholesale suppliers.

You should take the time to make sure you are familiar with the types of cuts that are commonly available so that you will know the type you are looking for. The round cut is one of the most popular and very classic cuts on the market. This type of cut lends itself very well to a very classic design and tends to designate a very traditional person. Do you consider yourself or your spouse as being traditional? If so, this might be the best cut of diamond to choose. A round solitaire diamond is very classic and traditional. Part of the “classic traditional” flavor of this cut is the connection between the round shape of the stone and the metal body of the ring. The circle of the ring reflects the roundness of the stone, where the circle signifies eternity and unity.

You may also wish to consider the marquis cut. This type of design cut is usually associated with royalty or elegance. This cut will give the diamond additional reflective qualities that are not matched by other cuts. The marquis cut also gives the illusion of having more depth than what reality dictates. The marquis cut is usually associated with an air of sophistication, if that is what your future spouse reflects. Another cut of diamond that is very unique is the heart shape. This cut is typically more expensive than other cuts, simply because of the additional skill and craftsmanship that is required to make such an intricate cut on a gemstone. The heart shape of course will indicate the attribute of love in an obvious manner, but this cut also subtly states that skilled artists, effort, and expense were involved in the creation of this stone. Another cut that has been gaining a bit of popularity in recent years is the pear cut. This cut designates the attributes of unique, young, as well as new and fresh. Like the heart cut, the pear cut will cost a bit more than other cuts because of the additional effort and skill required to create this cut, but owners of pear diamond cuts are extremely happy with the end result. In order to choose the good diamond, the first thing you must know what you look for and the prices of it. I think if you have fully knowledge about the diamond, you will choose beautiful and good diamond.

The Facts About Blue Diamonds

By: David Cowley

Diamonds are composed of carbon atoms that have been subject to extreme pressure and heat. If the diamond contains no impurities then the color will be crystal clear. Nature rarely creates anything that does not have any impurities in it. Most diamonds will contain some amounts of nitrogen atoms. If a few of the millions of carbon atoms have been replaced by nitrogen atoms, then structure of the diamond will not be significantly altered but the clarity will be changed.

When sunlight, which contains all colors, passes thought a diamond some of the light waves will be reflected by the nitrogen. The amount of color displayed is dependent on the amount of nitrogen involved. When we see color it is because the object we are looking at reflected a specific wavelength of the light spectrum. A good example of this is a pair of blue jeans. The jeans absorb all of the light except the blue light, which is reflected by the jeans.

In the case of a blue colored diamond some of the nitrogen has been replaced by Boron. Boron will reflect the blue wavelength of the light spectrum. The higher the concentration of boron the more color will be showed. At a level of one or a few boron atoms for every million-carbon atom, an attractive blue color results. Natural diamonds of this color are rare and highly priced, such as the Hope diamond. The Gemological Institute of America (GIA) has developed a color chart for grading diamonds.

GIA Color Chart.

D, E, F = Colorless
K, L, M = Faint Color
N, O, P, Q, R = Very Faint Color
S through Z = Light Color

Colored diamonds are very rare and very expensive. The Blue diamond is one of the rarest, and in my option the most desirable of the colored diamonds. The Hope diamond, which can be viewed in the Smithsonian Institution in Washington D.C., is the most famous blue diamond in the world, and at 45.52 carats the largest.

The Hope Diamond is more than a billion years old and it is the worlds' largest deep blue diamond. It was first found in Golconda, India in the early 1600s and has had a very checkered past ever since. It has crossed oceans and continents many times, has been owned by Kings and Commoners, has been stolen and recovered, sold and resold, cut and re-cut.

Famous Blue Diamonds are valuable investments and include such stones as The Queen of Holland, The Blue Empress, and The Regent Diamond. There are very few blue diamonds and the owners rarely sell these because of their value. The blue stones that are famous come in a wide range of hues. There are at least six different shades of blue in the diamonds that have become famous. The shade of the diamond is usually a matter of preference for those looking for special colors in the diamonds that they buy.

The famous blue diamonds come in different shapes including pear shaped and octagon shaped. The cut of these valuable gems is especially important for large, colored stones and the cut must enhance the natural beauty of these wonderful gems. Sometimes the largest stones that are found with a blue color are studied extensively before any cutting is begun.
