When shopping for a diamond, it is important to know how they are evaluated. Our comprehensive guide helps you understand the most important characteristics-carat, color, clarity, cut, and more-to ensure the maximum quality and value of your selection.
Every diamond is unique, and there are a variety of factors which affect the price of a diamond. Focus on those factors most important to you, and choose a diamond that satisfies your individual standards for beauty and value. This might be a very different diamond than someone else with a similar budget would choose. At USRAA, we want to help find the best diamond jewelry for you.
You also have access to a personal jewelry consultant; who can walk you through the diamond selection process or answer any questions you have. CALL online, or call +919830775678 now.
The cut of a diamond refers to its proportions. The Cut Scale ranges from Excellent to Poor. It is one of the most important factors to be considered while choosing diamonds.
A polished diamond’s beauty lies in its complex relationship with light: how light strikes the surface, how much enters the diamond, and how, and in what form light returns to your eye.
Diamonds allow light to be reflected and dispersed as a rainbow of color. Graded on an alphabetical scale from D (colorless) to Z (light yellow), a diamond's color rating indicates the degree of yellowness in the stone. The most valuable diamond is completely colorless.
Although many people think of gem quality diamonds as colorless, truly colorless diamonds are actually very rare. Each letter grade represents a range of color and is a measure of how noticeable a color is.
Diamonds come in many different shapes, and USRAA offers the highest quality certified diamonds to satisfy all tastes. Each diamond shape possesses its own unique quality, so exploring and learning about the various shapes is worth your while.
A round diamond will typically gives more flexibility in terms of balancing cut, color, and clarity grades while still getting the fire and brilliance you want. Princess is the most popular non-round diamond, it has pointed corners and is traditionally square in shape.
A carat is the unit of weight by which a gemstone is measured. The carat-weight of a diamond is the easiest measurement of the 4C’s to determine. Carat-weight is not a factor which denotes the quality of a diamond, but merely its size by weight.
The word "carat" derives from the carob seeds that people used in ancient times to balance scales. So uniform in shape and weight are these little seeds that even today's sophisticated instruments cannot detect more than three one-thousandths of a difference between them.
"Carat” is not to be confused with "karat," which is used to indicate the purity of gold.
One carat is subdivided into 100 "points". Therefore a diamond measuring 75 points is 3/4 carat in weight, or 0.75ct. There are five carats in a gram.
The size of a diamond is proportional to the carat-weight of a diamond. When rough diamonds are cut and polished into finished diamonds, as much as 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 2 one carat diamonds of the same quality. However, two diamonds of equal carat-weight can differ greatly in value due to their cut, color, and clarity.
Carat-weight by itself will not reflect a diamond’s size. Instead, two other factors must be considered:
Since a diamond is viewed from top when set into a ring or pendant, it is essential to determine the distance across the top of a diamond. A deeply cut diamond has a greater proportion of its total weight "hidden" in the depth, resulting in a smaller diameter than a well cut diamond.
The amount of light reflected from a diamond depends on its cut grade. Hence, when a diamond is well cut, maximum light is reflected from the top and makes it appear larger. It is therefore possible to get a diamond of lower carat but with higher cut grade and vice versa.
Carat is abbreviated to "ct" or "CT" when describing a single stone. "TCW," meaning "total carat weight," is added when jewellery is set with multiple diamonds.
It has to be noted that the carat weight does not refer to exactly one figure. It comprises of stones within a certain weight range. For example:
1 carat - Stones in weight range of 0.95 ct to 1.05 ct
0.75 carat - Stones in weight range of 0.72 ct to 0.76 ct
0.50 carat - Stones in weight range of 0.47 ct to 0.56 ct
0.25 carat - Stones in weight range of 0.23 ct to 0.26 ct
A certificate is a blue print of a loose diamond. Wholesalers, retailers, and consumers know a certificate as either a diamond grading report or diamond dossier. A certificate will tell a diamond's exact measurements, weight, cut and overall quality.
Every piece of jewelry from USRAA comes with a Certificate of Authenticity which is independently certified for Solitaire (above one carat) by GIA (Gemological Institute of America), IGI (International Gemological Institute), HKD (HKD Diamond Laboratories - Canada) or EGL (European Gemologist Laboratories) who are the world's top diamond grading laboratories. This certificate guarantees that your jewelry is made of what we say it's made of and that the quality and craftsmanship are top notch.
Clarity refers to how clear, or "clean" the diamond is. Almost all diamonds have tiny imperfections or “inclusions” but they are not always visible to the naked eye. Diamonds with few or no imperfections receive the highest clarity grades.
The Clarity Scale includes eleven clarity grades ranging from Flawless to I3. Because diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond that lacks any internal and external characteristics. These characteristics are a byproduct of its formation and help gemologists separate natural diamonds from synthetics and simulants, and identify individual stones.
