LET'S TALK ABOUT THE 5Cs; CUT, CLARITY, COLOUR, CARAT & COST.

CUT:

Possibly the most important of the Cs.

Each diamond is expertly faceted to bring out the potential of the gemstone. A high cut grade means a high degree of brightness, spectrum colours and scintillation (referred to as the face-up appearance by gemmologists). Diamond cuts are graded in 5 levels:

  1. Excellent
  2. Very Good
  3. Good
  4. Fair
  5. Poor 

To determine a diamond's cut grade, an optical measuring device creates a three-dimensional model to determine the diamond's proportions and angles. The interrelations between these various dimensions will greatly affect how light reacts once it enters and how it behaves upon exiting the diamond. By using sophisticated computer modelling, it is possible to grade the cut of each stone.

CLARITY:

Diamonds are naturally formed under immense heat and pressure, clarity is a measure of the number and size of the tiny imperfections that occur in almost all diamonds. Because these imperfections tend to be microscopic, they do not affect a diamond's beauty in any discernible way. Thus, while the brilliance and sparkle of a well-cut diamond can help camouflage the imperfections of a diamond with a lower clarity grade, it is difficult to imagine a scenario where a diamond's imperfections are so large and prominent as to mar a diamond's sparkle and brilliance.

The very best and rare clarity is internally flawless (abbr. IF). Because many inclusions are not visible to the naked eye, diamonds are graded under 10x magnification.                                                                                         

COLOUR:

A diamond’s colour is graded by the lack of colour present. The highest grade is ‘D’ and extends to ‘Z’.  At Monarc Concierge we usually use G-H, but we can help source the right diamond for your budget.

D = Absolutely colourless. The highest colour grade. Extremely rare.

E-F = Colourless. Minute traces of colour can be detected by an expert gemmologist. A rare diamond.

G-H = Near-colourless. Colour difficult to detect unless compared side-by-side against diamonds of better grades. Excellent value!

I-J = Near-colourless. An exceptional value with slightly detectable warmth or tone.

K-Z = Noticeable colour.

CARAT WEIGHT:

Diamond weight is measured in carats; one carat equals 200 milligrams in weight. All C’s combined means no two stones are the same. 

To gain a precise understanding of diamond size, Monarc Concierge recommends considering carat weight with two other characteristics: 1) the distance across the top of the diamond measured in millimeters, and 2) the diamond's cut grade.

It is important to measure the distance across the top of the diamond as this is how we view a stone when set into a ring.

A diamond's cut grade should also be considered because, as we noted in the cut grade section, when a diamond is cut with the proper proportions, the maximum amount of light (or sparkle) is returned out of the top of the diamond. Thus, when a diamond is well cut, the light reflected out of the top makes it appear larger. In addition, much of the weight of a poorly cut diamond, for example, may be "hidden" in the base of the diamond, making the diamond appear smaller than its carat weight would imply. It is therefore possible to have a diamond of a lower carat weight, but higher cut grade, that appears larger than a diamond with a larger carat weight, but poor cut.

Once you've selected your cut, colour, and clarity grade, it's easy to determine the carat weight of diamond that will fit within your budget.

Much as there are 100 pennies in a dollar, a one-carat diamond is comprised of 100 points. Hence, 50 points is equal to 1/2-carat, and so on.

This chart illustrates how diamonds of different carat weights look when set in a ring. Note that a 2-carat diamond does not appear to be twice the size of a 1-carat diamond when viewed from the top.

 

COST:

As with most things in life, we recommend choosing the best quality stone over size. Once you've selected your cut, colour, and clarity grade, it's easy to determine the carat weight of a diamond that will fit within your budget.
