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.

All about Diamonds

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.

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.

A Buying Guide for Loose Diamonds

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.

Diamonds from Light to Dark

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.

Why Fancy Colored Diamonds Continue To Be Trendy

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.

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.

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.

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.

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.

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.

GIA Certified Diamonds

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.

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.
