How to Buy a Diamonds

Diamond Facts

The first diamonds were mined in India over 2800 years. The diamonds that we find today are all very old. In fact, most are 900 million years old or more, with the oldest known diamond being 3.2 billion years old. Like snowflakes, each diamond unique. No two diamonds are exactly the same.

There are several things to consider when learning buying diamond, and you should never rush into buying a diamond without first having done a little research on how diamonds prices.

The “4 C's”

Everyone has many things to consider when determining how to buy a diamond. Throughout the world, jewelers use of "four Cs" as a way to describe the value of a diamond. If you want to learn to buy a diamond or Buy Diamonds Online, you must learn what the 4Cs is, and how each part affects the value of a diamond.

4Cs is cut, clarity, carat and color.


How to Buy a Diamond based on the court:

The cut of a diamond describes how an artisan angles the gemstone to best reflect light through the diamond, causing it to sparkle. A quality cut brings out the beauty of a diamond and makes it more valuable, while the poor cut diamond will sell for less because it is not as bright or brighter.

How to Buy a Diamond based on Clarity:

The clarity diamonds refers to how the diamond is clear when you look through it. A perfect diamond is rare; most have inclusions and flaws, although many can not be seen without magnification. When you look at a diamond for clarity, see if there are dark spots inside the diamond.

How to Buy a Diamond based on Carats:

Larger diamonds prices more than smaller diamonds, even if the size of carats and diamonds are the same. For example, no one carat diamond costs more than three diamond rings, for a total carat. This is because larger diamonds are rarer to find. When diamonds are cut, they lose about half the size.

How to Buy Diamond by color:

The actual color of a GIA diamonds is a personal preference. But diamonds are colorless, known as white diamonds are the rarest and therefore cost more. Diamonds also come in different colors such as yellow, green, blue and pink, for example.

Certificates and Appraisals

In addition to understanding what to look for in regards to the 4 C's when learning how to buy a diamond, you should also learn how to read certified Diamonds details about the uncounted diamond and perhaps have any diamond you are interested in professionally appraised by an independent organization.  You may not want to accept the appraisal done by the jeweler for the simple fact that they are biased and may appraise the diamond for slightly higher than it's actual worth in order to gain more money for the sale of the diamond.

How to Buy a Diamond

“The ultimate gift of love that says so much will be cherished always, and lasts forever.”

Diamonds were first formed billions of years ago some 100 miles beneath the earth's surface through a process of tremendous pressure and temperatures of 2000 - 3000 degrees Fahrenheit. Volcanic activity brings diamond crystals much closer to the earth's surface. 

The temperatures they are formed at are about 900 - 1300 C in this part of the Earth's mantle where diamonds form. The pressure is between 45 - 60 kilo bars. (kB) 50 kB = 150 km or 90 miles below the surface 60 kB = 200 km or 120 miles below the surface.

To produce a single one-carat diamond, 250 tons of earth will be mined. 

Gem-quality diamonds are made up from less than 20 percent of the diamonds mined worldwide.The first written notation of precious diamonds dates back to around 500 B.C.In their purest state, diamonds are brilliant and entirely colorless.

Diamonds are found in a variety of colors. Blue and pink diamonds are among the rarest, and yellow and brown as among the most common.The diamond is the hardest natural substance found on the earth.

There are one or two things you should know before you jump into that diamond purchase. Okay, there are actually four things - Color, Cut, Clarity and Carat - better known as the 4 C's.These are the criteria jewelers use when grading diamonds, and they're the ones you'll need to understand to buy the right diamond for you. 

And then there's the "Fifth C":

• Certificates

Cut

Cut is probably the most important, and most challenging, of the four Cs to understand. The brilliance of a diamond depends heavily on its cut. 

Clarity

Most diamonds contain some inner flaws, or inclusions, that occur during the formation process. The visibility, number and size of these inclusions determine what is called the clarity of a diamond. Diamonds that are clear create more brilliance, and thus are more highly prized, and priced. 

 

Color

Colorless diamonds are the most desirable since they allow the most refraction of light (sparkle). Off white diamonds absorb light, inhibiting brilliance. 

Carat Weight

A carat is the unit of weight by which a diamond is measured. Because large diamonds are found less commonly than small diamonds, the price of a diamond rises exponentionaly to its size.

The Fifth C: Certificates

The diamond certificate, which is sometimes called a grading report, is a complete evaluation of your diamond that has been performed by a qualified professional with the help of special gemological instruments. Each stone bears its own recognizable, individual characteristics, which is listed on the certificate.

DIAMOND CARAT

What is Diamond Carat?

The term "carat" goes back to the traders of the ancient world. A standard weight was required for precious gems as merchants of the ancient Mediterranean and Middle East were dependent on the ability to trade with a reasonably consistent unit of measurement. It was this need that lead to the adoption of seeds and grains as widespread accepted units of measurement.

A diamond's weight is represented in carats. Carat is a measurement of weight, NOT size. Weight impacts the price most dramatically out of the various diamond characteristics. This is why some diamonds have poor cut to retain diamond rough and larger carat size equating to a higher selling price. Diamond size is dependent on your budget and needs to be considered equally with the other characteristics of colour, cut and clarity in order to purchase a quality diamond. 

The Value of the Diamond is affected by its Weight:-

It is important to be aware that while the term carat refers to a diamond's weight, it does not refer to its dimensions or shape. The carat weight of a diamond can have an effect on its dimensions and shape, but neither the dimensions nor the shape is wholly dependent on the carat weight. For example, you could find yourself looking at two diamonds that look equal in size as you look down upon them. This does not mean that they have the same carat weight, however. A diamond can be cut to look larger than it is, through increasing its diameter and decreasing its depth, or through other cut techniques. The term carat is used to reference the diamond's actual weight, nothing more and nothing less.

Diamond carat weight affects the price of diamonds more than any other determinant. A diamond that is double the size of another diamond can be up to four times the price. This significant movement in price is because of the relative scarcity of larger diamonds. A combination of a large size (1 carat+) with the best colour (D), best clarity (IF) and excellent/ideal cut is so rare the price is multiplied several times when comparing a similar size with poorer features. 

Selecting Diamond Carat:-

The popular carat sizes are 0.50ct, 0.75ct, 1.00ct, 1.50ct and 2.00ct. Often diamond cutters will leave more rough diamond in order to achieve a larger carat weight and achieve a higher selling price. There are often bargains to be found at just under these most popular sizes and many of these bargains can have superior cuts which equate to more diamond sparkle and life. Diamonds with thick to very thick girdles are often intentionally cut to increase weight and this doesn’t improve performance it just costs you more (something to watch for). In recent years, having a 1.00 carat+ diamond was the best and most desired with no regard to quality, but as consumers are educated, (mainly because of the internet), more emphasis is placed on cut and visual performance. In the coming years dinner table diamond talk will be around quality rather than size and this could be something to consider.

Determine how much money you have to spend, and then decide on the cut of the diamond.  Once you have these two pieces of information narrowed down, you can start browsing the diamonds in your price range, in the style you want, and find out what diamond carat you are in the market to buy.

Diamond is the Hardest

Diamonds have been treasured as gemstones since their use as religious icons in ancient India. Their usage in engraving tools also dates to early human history. The popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, growth in the world economy, and innovative and successful advertising campaigns.

Diamond is the ultimate gemstone, having few weaknesses and much strength. It is well known that Diamond is the hardest substance found in nature, but few people realize that Diamond is four times harder than the next hardest natural mineral, corundum (sapphire and ruby). But even as hard as it is, it is not impervious. Diamond has four directions of cleavage, meaning that if it receives a sharp blow in one of these directions it will cleave, or split. A skilled diamond setter and/or jeweler will prevent any of these directions from being in a position to be struck while mounted in a jewelry piece.

 
The most familiar use of diamonds today is as gemstones used for adornment, a use which dates back into antiquity. The dispersion of white light into spectral colors is the primary gemological characteristic of gem diamonds. In the 20th century, experts in gemology have developed methods of grading diamonds and other gemstones based on the characteristics most important to their value as a gem. Four characteristics, known informally as the 4Cs, are now commonly used as the basic descriptors of diamonds: these are carat, cut, color, and clarity. A large, flawless diamond is known as a paragon.

In terms of its physical properties, diamond is the ultimate mineral in several ways:

1. Hardness: Diamond is a perfect "10", defining the top of the hardness scale, and by absolute measures four times harder than sapphire (which is #9 on that scale).
2. Clarity: Diamond is transparent over a larger range of wavelengths (from the ultraviolet into the far infrared) than is any other solid or liquid substance - nothing else even comes close.
3. Thermal Conductivity: Diamond conducts heat better than anything - five times better than the second best element, Silver!
4. Melting Point: Diamond has the highest melting point (3820 degrees Kelvin)
5. Lattice Density: The atoms of Diamond are packed closer together than are the atoms of any other substance
6. Tensile Strength: Diamond has the highest tensile strength of any material, at 2.8 gigapascals. However, that does not quite translate into the strongest rope or cable, as diamond has cleavage planes which support crack propagation. The strongest ropes can likely be made from another material, carbon nanotubes, as they should not suffer from the effects of cracks and break. Still, if a long, thin, perfect crystal of diamond could be manufactured, it would offer the highest possible pulling strength (in a straight line - don't try to tie it in a knot!)
7. Compressive Strength: Diamond was once thought to be the material most resistant to compression (the least compressible). It is the material that scientists use to create the greatest pressures when testing matter. However, the rare metal Osmium has recently been shown to be even less compressible (although it is not as hard as diamond). Diamond has a bulk modulus (reciprocal of compressibility) of 443 GigaPascals (GPa). The bulk modulus of the metal osmium has recently been found to be 476 GPa, about 7% greater than diamond.

Fancy Colored Diamonds

Fancy Colored Diamonds:-

Many people are beginning to favor the fancy, vivid colored diamond gem diamond on transparent or traditional white. Some diamonds are found in their natural colors when they are mined, others become colored by gemologists and jewelers during a treatment. To make them more affordable for the average consumer, companies have begun to address the color of the diamonds of lower quality to make a less desirable yellow or brownish tinted diamond and turn it into a beautiful, brightly colored diamond.

Diamond color is one of four major characteristics that are considered when determining a diamond's quality and value. They are known as the 4C's, and the remaining three are diamond clarity, diamond cut, and diamond carat weight.

Diamonds are not all truly colorless, but it's the colorless diamonds, sometimes called white diamonds, which all other shades are judged against.

The Gemological Institute of America (GIA CertifiedDiamonds) has devised a set of guidelines to grade diamond color. The color of graded diamonds is compared to the color of control stones, which are preselected gems of a specific color.

Natural fancy color diamonds get their complexion in different ways:

     Trace elements in the diamonds can produce color; nitrogen creates a yellow diamond.

    

   From different trace elements present in the stones, such as nitrogen, which produces a yellow diamond?

     From exposure to radiation during the diamond's creation. Green diamonds are an example of gems affected by radiation.

      

   inclusions, regarded as undesirable in a colorless stone, often contribute unique tones and interesting flashes of color in a fancy color diamond.

Making the Color More powerful:-

Fancy color diamonds are more popular than ever, so gemologists have developed ways to create affordable versions by treating less desirable diamonds. Irradiation, followed by a high heat treatment, turns brownish and yellow diamonds into colorful show-stoppers, and at a price you can afford.

The GIA grades the saturation of color by 9 different verbal categories. They are: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Dark, Fancy Intense, Fancy Deep and Fancy Vivid. In general, colored diamonds that run from Fancy through Fancy Intense through Fancy Vivid will be the overall quality line which produces the most expensive of colored diamonds in any given color.

Synthetic Diamonds are another Option

Synethic colored diamonds are another option. They're real diamonds, but they are created in a lab. Synthetics make owning a fancy color diamond a reality for those of us who couldn't afford a natural stone.
