DIAMOND EDUCATION

DIAMOND EDUCATION

The Greek word for diamond, "adamas," means "unbreakable." Diamonds are the hardest raw materials on earth and have long been adored for decorative purposes. They consist of crystalized carbon that has been forged in immense heat (about 1,250°C) and under high pressure (40-60 atmospheres) at depths of 150-200 kilometers below Earth's surface. Volcanic activity sends the raw crystals to the surface. Most diamonds are over 100 million years old.

4Cs of the Diamond

Carat

The "carat" is the unit of weight by which diamonds are traditionally measured. One carat is equal to one-fifth of a gram (0.2g). Each carat is subdivided into 100 points. The abbreviation for carat is Ct.

Diamond Cut

Diamonds in this range are considered the finest and exhibit a rare and stunning interaction between light and the stone's facets. They reflect the light better than any other category of diamonds.

Diamond Cut Signature

Diamonds in this range are considered as having the highest cut grade. The interaction of facets shows a good balance and delivers fire and brightness in a diamond.

Diamond Cut Ideal

Diamonds in this range produce slight fire and sparkle compared to the ideal cut diamonds and deliver slight darkness.

Diamond Cut Very Good

Diamonds in this range reflect limited light and brilliance.

Diamond Cut Good

This clarity level is considered flawless or internally flawless. These diamonds do not exhibit inclusions. Internally flawless diamonds may exhibit only faint external blemishes which are removable by polishing. Flawless and internally flawless diamonds are very rare.

Diamond Clarity FL - IF

Diamonds with this clarity may contain very, very slight inclusions, that are extremely hard to detect under a 10X magnification mirror and are not noticeable with naked-eye.

Diamond Clarity VVS1 - VVS2

Diamonds with this clarity contain very slight minor inclusions that can be seen under a 10X magnification mirror and are not noticeable to the naked-eye.

Diamond Clarity VS1 - VS2

Diamonds in this clarity group include slight inclusions that can be detected under a 10X magnification mirror.

Diamond Clarity SI1 - SI2

Diamonds contain slight inclusions, are noticeable under graded 10X magnification, and visible to the naked eye under close examination.

Diamond Clarity I1

Diamonds contain obvious inclusions that may affect the brilliance of the diamonds. Inclusions on these diamonds are visible to the naked eye.

What is a Diamond Certificate?

Design Your Product

Diamonds are natural stones so each one comes with unique internal and external characteristics. In addition to size and color, birthmarks inside the diamond have an impact on its rating. The value of a diamond is based on the combination of all these qualities.

The four characteristics that are used to classify diamonds, known as the "4Cs of the diamond," are color, clarity, cut, and carat. These are evaluated by diamond professionals and often get documented in detail. The documentation is called a grading report or diamond certificate. Diamond certificates are important because they show the quality and value of your diamond.
