About Diamond Certification

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.

Diamond Shapes

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.

The four stages of a Diamond

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 Free Diamonds

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.

The Four C’s

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.

Step Cut Diamonds

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.

Light and Diamond Grading

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.

Diamond Side Stones

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.

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.

Diamonds vs. Graphite

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.

Diamonds and Their Colors

Diamonds and the Mohs Scale

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.

The Process of Diamond Formation

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.

The earth underneath thick, geologically stable landmasses known as cratons provide the intense pressure needed to help diamonds take shape.

How lighting affects diamond brilliance

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.

From Underground to the Surface

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.

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.

Diamond Purity

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.

Steps Taken Before Diamond Faceting

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.

Rose Cut Diamonds and Macles

Diamonds Radiation and Fancy Colored Diamonds

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.

Diamond Clarity Characteristics

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.

Fancy Diamonds

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.

Diamond Cutting Technology

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.

Diamond History

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.
