Many factors that go into creating diamonds so they are suitable for diamond rings and other jewelry. Not only must the diamonds be mined and checked for provenance, the stones are also examined to see if they are suitable for jewelry or other purposes. Jewelry grade diamonds are then faceted to bring out the brilliance and luster they’re celebrated for. With all the work and the many hands that a diamond must go through, some people enjoy the peace of mind that comes with certification, attesting to the quality of the stone.
Many diamond lovers know about diamond cuts, and how a beautifully cut diamond lights up the interior of a stone. It’s not uncommon for a person to have a favorite cut, be it a heart, an emerald or an oval. However, it’s also important to remember that there is a difference between the cut of a diamond and its shape. The former refers to faceting and how it makes the brilliance and clarity of a stone come to life. The other refers to the outline of a jewel.
The most common cut is the round brilliant, which provides most of the round diamonds on the market. Everything else, from heart to cushion, is known as a fancy shape. Valentin Magro offers diamonds in square, rectangular, triangular, heart, oval, marquise and pear shapes.

A diamond is a mineral consisting of over 99.95% crystalized carbon, its atomic structure making it the hardest natural substance known to man. They form between 75 and 120 miles below the earth’s surface, where the temperature and pressure are powerful enough to form this unique gem. Volcanic eruptions from over 50 million years ago sent these stones to the earth’s crust.
Conflict Diamonds are stones which are mined under duress, by men, women and children who are forced into service by rebels. Once these diamonds are produced, they are sold to raise funds for weapons and activities that oppose internationally recognized governments. The miners of these gems receive no benefits, but must endure horrible experiences.
After a diamond is processed into its final form, it is analyzed via a system where it is graded by Cut, Clarity, Color and Carat. Together, they are known as the 4 Cs, a system created by the Gemological Institute of America (GIA) to give jewelers an objective and uniform method of evaluating diamonds. Each of the 4 Cs is connected with a list of grades to determine what is optimal, poor or in between. The GIA states that items of great value often come with documentation verifying their worth, and jewels should be no different. A report describing what your diamond is like would help add to its significance and ability to be identified. Continue reading for a more detailed explanation on the 4 Cs of a diamond.
Diamonds are prized for their ability to reflect light. This is most celebrated in brilliant cut diamonds, which combine brilliance, fire and luster to showcase the jewels bright qualities. While step cut diamonds aren’t as bright, they still showcase the beauty of the diamond crystal. Step cut diamonds are square or rectangular diamonds with a faceting style distinct from brilliant cuts. Their tables and culets, or upper and bottom most facets, are broad while other facets on the jewel are downplayed. Facets sit parallel to one another, emphasizing a geometric look. The interior of the diamond is highlighted, with less brilliance to distract from the view.
Diamonds are known for how they interact with light, which in turn influences qualities such as color, clarity and cut. The many aspects of diamonds with light can make evaluation a challenge.
Side stones are jewels, commonly diamonds, which are used to flank the sides of a central gemstone, which is often the largest gem in the design. They’re most common on rings, though side stones may be found on pendants, brooches and other pieces of jewelry. Depending on the design, they may be the only embellishment on the ring, or may be accompanied by halos, pave sets and other decorative techniques.
The diamonds used at Valentin Magro are certified by the Gemological Institute of America. Each of these gemstones come with a report detailing the qualities of its jewel. GIA certified diamonds also come with unique identification numbers, making verification easier as well as distinguishing individual diamonds from one another. To ensure our clients receive reliable information regarding their certified diamonds, we use an independent third party laboratory. This step ensures that there’s as little bias as possible with the diamond grading. We want the best for your clients, which includes honesty.
The Gemological Institute of America aims to be as precise as possible when it comes to certified diamonds. Jewels are placed in uniform packaging before arriving at the laboratory to reduce factors that may skew the grading process. The Gemological Institute of America developed the concept of the four Cs of carat, clarity, color and cut to create an objective standard for certified diamonds.
For a diamond to come to your hands, it must go through many steps. They’re formed 90-120 miles below the earth. Volcanic activity brings the jewels to the earth’s surface. Traditionally diamonds were mined in India, Brazil and later South Africa. Today’s loose diamonds are produced on five continents.
Like diamonds, graphite is made solely of carbon. At the molecular level, both minerals are made of a series of dual pyramids connected in a lattice structure resembling a honeycomb. Regardless, the two are unlikely to be mistaken for one another.
When most people think of diamond color, white is the first thing to come to mind. Others might consider the various shades of yellow or brown, so subtle they must be detected by trained eyes. Still more may imagine famous colored jewels like the Hope Diamond.

A person may compromise with a moderately tinted stone or one with an inclusion or two more than planned. Sometimes a consumer will encounter a boon in the form of a high quality diamond for a reasonable price. This may seem too good to be true.
The Mohs Scale of Mineral Hardness determines a stone’s resistance to scratching. A mineral such as talc may be scratched by anything matching or exceeding its hardness. The higher on the scale a stone is, the less vulnerable it is to abrasions. Diamonds are at the far end, the pinnacle of hardness. At the same time, diamonds are admired for how its cuts draw out its aesthetic properties. Specialized tools are a must for bringing out the best in diamonds.
As with many gemstones, diamonds are formed as a result of geological activity. The conditions that leads to the creation of diamonds are very specific, requiring the right environment and materials. They take shape between ninety and one hundred and forty miles beneath the earth’s surface, in the upper mantle. The earth underneath thick, geologically stable landmasses known as cratons provide the intense pressure needed to help diamonds take shape.
Light helps to draw out the aesthetics of a diamond. A well-made cut showcases the beauty of the jewel by encouraging light to illuminate the diamond, split into many hues, and sparkle for the pleasure of the viewer. Not all forms of lighting are equal. Different types have varying concentrations that underscore specific diamond traits.
Rough diamonds are a product of nature, requiring countless years and specific conditions in order to take shape. Still more factors are required to bring them safely to the earth’s crust. From there, it is up to the efforts of people to find the jewels so they may be admired by others.
Diamonds are both beautiful and practical. The highest quality stones are usually set aside to be cut and set in jewelry. Less perfect gems and those made in laboratories are frequently used for industrial purposes. Diamonds’ hardness makes them ideal as abrasives, drill tips and cutting instruments.
Diamonds are carefully cut so light enters the jewel at optimal angles for brilliance. When other matter such as grease or soap cover a diamond, the angle light needs to brighten the diamond changes, but the stone does not.
Of all the four Cs of diamond quality, cut is the most complex to grade. This is in part due to the wide range of diamond cuts, and the subjective nature of aesthetics. People may have differing ideas as to what makes a cut beautiful, which in turn can make a verifiable cut grade tricky.

For diamonds to form in nature, they need the assistance of other rocks and minerals. Some provide the carbon needed to create the jewels, and others serve as a means of transport to bring diamonds to the earth’s surface. Still more stones serve as heralds, alerting explorers to the possibility of diamonds.
The chemical formula for diamonds is pure carbon. Its structure consists of a series of five atom units bonded together. Many diamonds however have quirks in their crystal.
There’s much to love about a diamond’s brilliance and fire, just as there is plenty to adore about their color and clarity. Sometimes a person finds the diamond of their dreams but are unable to find the perfect mount. On other occasions, someone may want a new gemstone to freshen up a piece of jewelry with deep meaning, like designer engagement rings.
Though diamonds have been coveted since the time of the Roman Empire, they weren’t always beloved for their brilliance. The immense hardness of diamonds, in addition to giving them powerful durability, also means that cutting and polishing is difficult without specialized tools and technology. Without careful faceting to highlight the stone’s optical properties, early diamonds had dark interiors and only shone on their surface.
The round brilliant diamond is one of the most popular of all diamond cuts. It’s a cut of choice for engagement rings, wedding bands, pendants and any other jewelry one can imagine. There is no single way to create a round brilliant, though jewelers are constantly experimenting with proportions, ratios and facets to create the brightest possible diamond, or an ideal cut.
Colors are pleasing to eye and often bring joy to the heart. However, every other color pales in comparison to the brilliance of gem stones that sparkle and shine along with displaying an ethereal hue.
All that glitters is not gold, and that applies to diamonds as well. How can one tell apart a real and a fake diamond? There are 4 standard ways of telling this.
Diamonds are admired for their beauty and the way they interact with light. While discoveries of new deposits and advances in mining have increased availability of the jewel, there are times people may wear jewelry with pretend diamonds, also known as simulants. Diamond simulants are created when people desire sparkling but inexpensive jewelry, for security purposes, or to replicate a well-known jewel. No matter how closely a simulant resembles a diamond, there are still ways to distinguish real from imitation.
It’s not uncommon for diamonds to have other materials within their crystal large enough to be viewed at 10X magnification or even with the naked eye. Depending on the nature of the included stone, it may be catalogued differently.
To transform a diamond from a piece of rough to a masterpiece of brilliance doesn’t happen immediately. This is partly due to diamond’s hardness, which makes cutting a challenge.
Larger diamonds are rarer than smaller ones. Cutters strive to preserve as much carat as possible while highlighting the jewel’s best characteristics. In many instances, the final cut follows the outline of the rough, keeping more of the stone intact. The rose cut is one such example.
The earliest diamond cuts bear only the faintest resemblance to diamond cuts today. A combination of limited technology and differing tastes impacted the brilliance of the jewels as well as their shape.
Most diamonds mined lack the quality necessary to become gemstones. They’re used for industrial purposes which take advantage of the many unique properties of the stone. In addition to its intense hardness and optic properties, there are other traits, including how diamonds interact with heat.
Fancy color diamonds are rare. For every ten thousand diamonds mined, there is one Fancy diamond. Some hues, such as brown or yellow, are relatively common, while others like blue are less available.
Many gemstones, including diamonds, form under drastic conditions within the earth, often as a result of intense heat or pressure. The circumstances of their creation can be found within their crystals as clarity characteristics.
When most people picture diamonds, they imagine transparent colorless jewels. Diamonds in their purest state have no discernable hue. Most however contain traces of nitrogen, which may add subtle coloring to the crystal.
With single pointed edge and rounded end, the pear shaped loose diamond stands out among the traditional crowd of round and princess cut diamonds. Also called ‘teardrop’ diamond for its unique appearance, this distinctively shaped diamond is a popular choice for both connoisseurs and investors.
For early diamond cutters, the stone’s supreme hardness made diamonds tricky to shape. The invention of the scaif in 1496 used a wheel not unlike potter’s wheel, covered the surface with a mixture of oil and diamond debris, and clamps to hold diamonds against the wheel. This allowed multiple diamonds to be polished at once, as well as allowing cutters to fashion jewels with greater precision than before.
The most coveted gemstone, diamond is steeped in interesting facts galore. We are so much lured by its dazzling beauty that we forget to see beyond it.
When it comes to diamonds, value translates into rarity. With diamonds belonging to the common range, value is determined by the absence of color, as colorless diamonds are usually also the rarest. However, colored diamonds follow a completely different rule.
As lovely as diamonds are when set in jewelry, some people prefer to buy diamonds that are loose, or unmounted. Loose diamonds may be purchased with an eye to placing them in a mount later on, or in a piece of jewelry they already own.
Diamonds are gemstones millions of years in the making, formed under intense heat and pressure 75 to 120 miles beneath the earth’s surface. The supreme hardness of diamonds meant that the first diamond cuts mostly involved cleaning and evening the sides of the rough.

One of the ways to alter a diamond’s color is to irradiate it, turning the jewel green. The majority of verdant diamonds get their hues through the aid of humans. Though the earliest history of the Dresden Green is unknown, it’s confirmed that the 41 carat stone is the largest naturally green diamond known.
Some diamonds gain attention as single stones. Others garner fame when set with other jewels. The Napoleon Diamond Necklace is an example of the latter. It was commissioned in 1811 by Napoleon Bonaparte as a gift for his wife Marie Louise.
The Mughal cut was used in India during the 16th through 18th centuries. Rather than shaping the diamond to underscore its brilliance, this cut followed the lines of the original rough.
In an effort to meet demand, mining companies are making greater efforts to find stones measuring one hundred carats or greater. This has included reopening the Letseng diamond mine in Lesotho.
Diamonds are delivered to the earth’s surface with the aid of one of two rocks, kimberlite and lamproite. The two igneous materials have similar chemical composition, but are found in different locations.
