The 4 C's

Diamond Anatomy & Cut Quality

At the point when you’re looking for a Diamond, its brilliance and shimmer will attract you to the gems counter, and keep you enamoured long after you’ve made your jewel buy. Accomplishing most extreme splendour and shimmer requires magnificent cutting strategy, which is reflected in the precious stone’s cut evaluation. Of the 4Cs, no other ‘C’ has more effect on a precious stone’s appearance.


Understanding the 4 C’s of Diamond Shopping

Every one of the 4 C’s (Cut, Color, Clarity and Carat) assume a job in a jewel’s stunner, however it is hard to interpret one segment without anyone else. As an exhaustive entire, the 4 C’s cooperate with each other inside every jewel. When in doubt, we propose a top notch Cut regardless of anything else—as this incredibly impacts a precious stone’s delight and splendor—while adjusting a scarcely discernible difference on Color and Clarity to get the best value for your money. With the correct Cut, both a .9 Carat Round Brilliant (K Color, VS2 Clarity) and a 1.5 Carat Round Brilliant (I Color, SI1 Clarity) can be staggering.

It is imperitive that you locate the correct equalization of value and worth utilizing the 4C’s. Suppose you have a financial limit of $5,000. You have three choices: You can go with the most perfectly awesome quality conceivable and afterward you end up with just a 3/4ct jewel. You can disregard quality and up with a 1.75ct jewel that looks awful. Or on the other hand you can locate the correct offset and end up with a lovely 1.25ct jewel this way.


A Diamond’s Clarity grade assesses how clean a precious stone is from the two considerations and imperfections. Clearness is reviewed by the GIA on the accompanying scale:

In the event that (Internally Flawless)

VVS1 (Very, Very Slightly Included 1)

VVS2 (Very, Very Slightly Included 2)

VS1 (Very Slightly Included 1)

VS2 (Very Slightly Included 2)

SI1 (Slightly Included 1)

SI2 (Slightly Included 2)

I1 (Inclusions 1)

I2 (Inclusions 2)

Contingent upon the size, area and murkiness of flaws and incorporations, these defects can meddle with light as it goes through the jewel. At the point when this occurs, the splendor and excellence of the precious stone is dulled, detracting from the top notch Cut.

For Clarity, our essential suggestion is to guarantee the precious stone is eye clean, and that considerations are not meddling with light reflection.

Survey the stone to check whether it is eye clean and request affirmation from a specialist. An endorsement alone won’t reveal to you how a precious stone’s imperfections will affect the stone’s appearance and splendor.


Diamond Cut explicitly alludes to the nature of a precious stone’s points, extents, balanced aspects, splendor, fire, glimmer and completing subtleties. These elements straightforwardly sway a jewel’s capacity to shimmer, alongside its general tasteful intrigue. For instance investigate this delightful precious stone and this horrendous decision. The main issue separating the two is the cut.

The GIA grades Diamond Cut on the size of Ideal, Excellent, Very Good, Good, Fair and Poor. The Ideal and Excellent evaluations, contingent upon Diamond Shape, mean extents and points cut for most extreme splendor and fire.

How Light reflects through a precious stone

Cuts fluctuate altogether among precious stones and jewel cutters. On occasion, a shaper may focus on most extreme Carat weight, departing the precious stone excessively profound or unreasonably shallow for ideal light reflection. Different occasions a precious stone might be sliced to limit the quantity of considerations, improving its Clarity, yet swearing off most extreme shimmer. Indeed, even an Ideal cut precious stone may have a yellow tint that is excessively recognisable and takes away from the jewel’s excellence.

All the more significantly, however, is guaranteeing Cut is a point of convergence of your jewel choice. Indeed, even an unblemished 2 Carat Diamond without any imperfections or shading tinting can be dull if it’s not cut outstandingly well. Cut is the greatest pointer of excellence, and ought to be made need over the other C’s. For instance, this 1.50 Carat Round Brilliant is reviewed well for every “C” except comes up short on a vivacious shimmer.

It’s basic to take note of that a top evaluation assignment, as Excellent, doesn’t really demonstrate an exceptional jewel cut. Practically 55% of all jewels sold online are Excellent cuts. Some are staggering, while others are average. A case of a dazzling Excellent cut jewel is this 1.5 Carat Round Brilliant from James Allen.

Since Cut is so critical to a precious stone’s basic excellence, it’s vital to audit a jewel’s Cut cautiously and request the eye of a specialist.


Diamond stone Colour is reviewed regarding how white or dry a jewel is. The GIA grades precious stones from D to Z, with D being the most boring, and Z containing recognisable earthy coloured or yellow tint.

Diamond Colour Descriptions

The evaluating of precious stones typically mirrors these evaluations—some of the time altogether. Much of the time, the unaided eye can’t differentiate between two adjoining shading evaluated jewels, however the value distinction might be critical.

The most basic perspective with Colour is to decide whether it seems dismal corresponding to its setting. You likewise need to be sure that a precious stone is away from any tinting that removes or meddles with white and hued light reflections. The K Colour in this Cushion Cut Diamond, for instance, occupies from the radiance of the jewel while this I Colour Diamond is brilliant.

Splendor, or shimmer, is made from the manner in which the precious stone is cut. It isn’t profitable to buy a precious stone that diverts from this significant head trademark.

As a general suggestion, survey every jewel intently and request the help of a specialist. This is the most ideal approach to guarantee you’re not paying for an element (for example excessively high of Colour grade) that will go unnoticed, or buying a precious stone that diverts or meddles with light reflection.

Note: Certain hued precious stones are esteemed stones, similar to an extravagant pink or green jewel. Shading grades for these jewels are unmistakably unique in relation to customary “white” precious stones.

Carat (Size)

Regularly when individuals hear the expression “Carat Weight,” they think it alludes to the size of the precious stone. In fact, Carat alludes to the heaviness of the precious stone, not how huge the stone is.

Diamond Sizing Descriptions

A 1 Carat Diamond rises to 200 milligrams, or 0.2 grams—and weighs about equivalent to a fourth of a raisin. Contingent upon the Diamond’s Shape and how it is cut, two 1 Carat Diamonds may be very extraordinary in size.

While Carat weight is a component to consider when purchasing a jewel, the general appearance and brightness should convey more significance. For instance, an unremarkable 1.5 Carat jewel won’t sparkle as brilliantly—or draw as much consideration—as a staggering 1.0 Carat precious stone, regardless of the amount more it gauges.

Importance of the 4 c’s

Everyone of the 4 C’s add to the general magnificence of a jewel and make each stone novel. A Diamond, be that as it may, ought to be seen as a natural entirety. Since the eye experiences issues separating one segment without anyone else, for example, Clarity or Colour, it is essential to consider how the 4 C’s effect one another.

Which is the most significant of the four C’s?

Cut: The most significant part of a precious stone that most promptly impacts a jewel’s marvel. Search for significant levels of splendour and fire, and be eager to lessen your spending in different territories like Clarity or Colour to guarantee an excellent Cut.

Colour: The second most significant angle to concentrate on. A precious stone should look white or dreary to the unaided eye. Guarantee the Colour doesn’t divert or meddle with white and shaded light reflection.

Clarity: The third most significant trademark on the rundown. Pick a jewel that is eye clean. Flaws and considerations ought not occupy from the splendour or fire of a jewel.

Carat: Last however not least. Consider what is significant for you and the one you love, however recollect that brightness and excellence will surpass negligible weight every single time. Be available to bringing down your Carat weight to guarantee you buy a shocking precious stone.
