UNDERSTANDING THE  4c's OF A DIAMOND

At SRIKRISHNA Jellewers we adhere to GIA standards and have in-house trained graders. Each diamond is hand picked and goes through various levels of testing in our world class in-house lab, which includes a CVD detection machine too. We only deal with natural diamonds and leverage our CVD machine to ensure the quality is maintained with every diamond we source.

We provide two certification:






Round & Marquise cut diamonds are the most popular ones used by SRIKRISHNA.

The ROUND cut diamond is the most popular diamond shape, representing approximately 75% of all diamonds sold. All round diamonds are ideal brilliant-cut -- an ideal cut diamond is cut to ideal proportions & angles and has excellent polish and symmetry ratings. They are perfectly proportioned to refract light, producing that fire and brilliance up through to the table and crown.

The MARQUISE cut diamond, also known as the boat-shaped, or the eye-shaped, is a modified brilliant-cut. Because the marquise diamond is long and narrow, it can also create the illusion of greater size. Carat for carat, the marquise diamond has one of the largest surface areas of any diamond shape, making it a good choice when trying to maximize perceived size.









The 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world. The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.




Anatomy of a diamond





Diamonds are renowned for their ability to transmit light and sparkle so intensely. We often think of a diamond's cut as shape (round, heart, oval, marquise, pear), but a diamond's cut grade is really about how well a diamond's facets interact with light.





Cut scale ranges from excellent to poor


A polished diamond's beauty lies in its complex relationship with light. The mannificent display you see is made up of three attributes: Brightness is the combination of all white light reflecting from the surface and interior of a diamond. Fire describes the "flares" of color emitted from a diamond. Scintillation describes the pattern of light and dark areas and the sparkle you see when the diamond, the light, or the observer moves.

A diamond's proportions affects its light performance, which is turn affects its beauty and overall appeal. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light, and have increased brightness, fire and scintillation.

GIA assesses these factors for standard round brilliant diamonds in the D-to-Z color range.





Diamond Clarity refers to the absence of inclusions and blemishes.

Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called 'inclusions' and external characteristics called 'blemishes'.

The GIA Clarity Scale includes eleven clarity grades ranging from Flawless to I2 visible at 10x.





FL
No inclusions and no blemishes visible at 10x.

IF
Polish lines (blemishes left on the diamond during the polishing process) are located on the pavilion of this diamond.

VVS1
Pinpoint (mineral crystal trapped inside of the diamond during growth that appears as a tiny speck at 10x magnification) is visible only through the pavilion of this diamond.

VVS2
Pinpoint is visible only through the crown of this diamond.

VS1
Crystal is visible in the table facet of this diamond.

VS2
Crystal is visible in the table facet of this diamond.

SI1
Crystal is visible through the crown of this diamond.

SI2
Feathers (breaks in the diamond) are visible through the crown of this diamond.

I1
Crystal is visible through the table facet of this diamond. Pinpoints, a feather and a cloud (milky area composed of a number of pinpoints) are also present.

I2
Feather breaks across the pavilion of this diamond and is visible through the crown. Clouds are also present.

I3
Feathers break on both the crown and pavilion of this diamond. Crystals are also present.







The diamond color evaluation of most gem-quality diamonds is based on the absence of color. Many of these color distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price.

D-to-Z diamond color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to master set of established color value.




One carat equals 200 milligrams in weight.

For diamonds under one carat, each carat is divided into 100 points – similar to pennies in a dollar 0.75 ct = 75 points, ½ ct = 50 points.
