[They] are real diamonds. They have the same optical, chemical, thermal, and physical features.
– Matthew Hall, Director, Gemological Institute of America (GIA)
Diamonds are loved all around the world. There is nothing quite like a beautiful diamond to truly express one's love, commitment and affection for someone.
Purchasing a diamond could be an intimidating experience for many people but not once you’ve understood the key characteristics, which is very simple to understand.
We’ve created a simple guide explaining all the important characteristics and how each one of them affect the brilliance and value of the diamond, in a short while you’ll learn how to create the right balance in choosing you perfect diamond.
Diamond Size and Diamond Carat Weight
A diamond's weight is measured in carats. One carat is equal to 0.2 grams. The larger the carat the heavier the diamond.
One Diamond carat is divided into 100 point. A 0.25 carat diamond is the same as a 25 points or 1/4 carat diamond. Carat is often confused with size even though it is actually a measure of weight.
The size of a diamond is proportional to its carat weight. When rough diamonds are cut and polished into finished diamonds, up to 2/3 of the total carat weight may be lost. Since larger rough gems of high quality are found less frequently than smaller rough gems of high quality, a single two carat diamond will be more expensive than two one-carat diamonds of the same quality.
At Labgrown diamond Inc, we apply the same high quality standards to all of our diamond shapes. We have an exceptional collection of traditional round diamonds and we also offer the finest non-round, or "fancy-shaped", diamonds available. All of our certified diamonds are graded by the IGI to have FL-SI2 clarity, D-J color, and Ideal, Very Good, Good, or Fair cut. Our Signature Diamonds are the finest quality diamonds available, and we offer them in round, princess-cut, Asscher-cut, and emerald-cut shapes etc.Di
Inclusions found on a diamond can be considered nature's birthmarks, the distinguishing characteristics that make the stone unique. When grading a diamond, the amount of inclusions and blemishes has a direct impact on its clarity and value. Flawless diamonds containing no inclusions are extremely rare and very expensive. A majority of the commercially sold diamonds contains inclusions that are undetectable to the unaided eye.
A diamond's clarity rating is based on the size, number, and location of internal and external characteristics. Known as inclusions, internal characteristics include crystals, clouds, and feathers. External characteristics, or surface irregularities, are called blemishes. As most inclusions can't be seen by the naked eye, gemologists use a ten-power (10x) microscope to rate a diamond's clarity.
A diamond's color has a significant impact on its appearance. With its many prismatic facets, a colorless diamond reflects light into a spectrum of hues, a characteristic often referred to as "fire". The presence of noticeable color in a diamond may reduce its ability to reflect light. Consequently, diamonds with lower color grades will not show the same luminosity and fire as those with higher grades. The most valuable diamonds have little to no detectable color.
The diamond color scale begins at D (colorless) and ends at Z (light yellow). Diamond color is often difficult to discern when a diamond is viewed face up. Therefore, gemologists typically evaluate diamonds facedown against a pure white surface, illuminated by carefully controlled lighting. The diamond is then compared to master stones of predetermined color.
One of the most defining characteristics of a diamond is its cut. Diamond cut is the summary of a diamond's proportions evaluated using the attributes of brilliance, fire, and scintillation. While high grades of color, clarity, and carat weight affect a diamond, it's the cut that determines the symmetry of the stone's facets, its overall proportions, and its ability to reflect light. An expertly-cut diamond will achieve high levels of brilliance, sparkle, and durability. Even if a diamond is graded well in other areas, a poor cut can result in a dull, muted effect.
A diamond certificate, also known as a diamond grading report, is an easily understood document prepared by an expert gemologist that describes the key characteristics of a diamond. A certificate from a gemological laboratory verifies the quality of a loose diamond and allows non-experts to make educated diamond buying decisions.
