Which is Which and Why Should I care?

Brilliant with an unmatched strength, diamonds are hard to beat, or are they? Below we go over the 4 C's of diamond grading and along with that, a little information about moissanites that might have you switching sides. 

The 4C's of Diamond Grading

When choosing a diamond there are several factors to consider. These factors are what contribute to a diamonds price. The better the quality, the more rare and thus the greater the price. (Scroll to the bottom of the diamond section for our recommendations on the best diamond for value.)

Diamonds

Carat Weight

 

Diamonds are calculated by weight in carats. One carat is equal to 0.20 grams. There are factors which can make diamonds look larger or smaller such as it's cut, or it's shape. For example round and oval diamonds look larger than a square princess cut diamond. 

     0.50ct                   0.75ct                    1.0ct

        $                          $$$                   $$$$$

     1.0ct                        1.0ct                         1.0ct

         Flawless                         I1                   Black Diamond

                                                                    (Full of inclusions)

Clarity

 

Clarity grades diamonds based on natural flaws inside we call inclusions. These inclusions can come in various forms from white 'feathers or clouds' to black spots and pin points. Clarity is graded using letter from I to IF. We'll break down what each means in the charts below.  

Clarity

I3  I2  I1  SI2  SI1  VS2  VS1  VVS2  VVS1  IF  F

Best Value for clarity

Letter value meaning:​

  • I stands for Inclusion where the number grades the level of inclusions

  • SI means slight inclusion

  • VS means very slight inclusion

  • VVS means, you guessed it, very very slight inclusion (you can see where they are going with this)

  • IF stands for Internally flawless

  • F means completely flawless. The perfect diamond.

Colour

 

Colour grading of a diamond is more in reference to it's lack of colour. The grading scale is alphabetical and starts at D, near colourless. Once the colours become more pronounced they are graded in the 'fancy colour' range. Diamonds come in a large assortment of colours but for now we will focus on colourless. 

       D                 G-H                                                          Z

Best Value for colour

Hint: if you have a diamond with some colour in it, set it in a yellow gold setting to offset the yellow in the diamond. It will look near colourless next to the yellow gold. 

Ideal cut for light to enter and reflect back

Cut

 

Last, but very important, is cut. This refers to the diamonds proportion, symmetry, and polish. The cut of a diamond can make or break a beautiful gemstone. Without an excellent cut, the diamond won't give you the sparkle and scintillation that diamonds are so well known for. 

Letter value meaning:​

  • Excellent sometimes referred to as Ideal 

  • Very Good 

  • Good 

  • Fair 

  • Poor 

The better the cut, the more light reflected

Our recommendation for best value in a diamond is SI1 clarity, G-H colour, Excellent cut, and the largest carat weight your budget can afford.

Why Moissanite?

 

Lab created gemstones that are both stunning and affordable. Tough and durable, they are similar to sapphires and rubies. 

Diamond vs Moissanite.83.png

Moissanite

 

  • Hardness of 9.25 Mohs scale

  • Lab Grown

  • Refractive index 2.65-2.69

  • Dispersion 0.104

  • Colours are clear to near clear

  • Clarity are all eye clean (SI1 or better)

  • Cost approx. $650

for a 6.5mm round

Diamond

 

  • Hardness of 10 Mohs scale

  • Mined or Lab Grown

  • Refractive index 2.417-2.419

  • Dispersion 0.044

  • Colours vary

  • Clarity ranges from I3 to Flawless

Benefits of Moissanite

  • Colourless or Near-Colouless Options: We only use colourless unless we are trying to colour match with a set.

  • Larger gemstone for a lot less money

  • Durable enough to last a lifetime

  • Exceptional sparkle and fire: 2.4x the dispersion of diamond giving it more fire
