DIAMONDS

For most people buying a Diamond Engagement Ring or Diamond Jewellery can feel like a daunting experience, and in most cases the experience feels this way because you don’t have enough knowledge of the different aspects on choosing that perfect Diamond for you.  The process of purchasing that perfect Diamond does not need to feel like this and here at Richardson’s Jewellers we have been helping generations of people like you choose the perfect Diamond in a straightforward and simple way.

The 4 C’s are what we recommend at Richardson’s Jewellers which are Cut, Clarity, Carat  and Colour.  However, there are a few other C’s we will reference in this section and that is Certificate, Cost, Communication and Confidence.

CUT

The Cut of the Diamond not to be confused with the Shape of the Diamond is one of the most important characteristics of the 4 C’s and will be one of the greatest overall influences on the beauty of that particular stone.

  • The Cut of the Diamond or the proper proportions will allow the best use of light reflecting through the stone, or determine what we generally refer to as how much sparkle is in the Diamond.
  • When the Cut of the Diamond is within the correct proportions, the light is returned out of the top of the stone also known as the Table of the Diamond.
  • If the Diamond is cut too deep the light tends to escape out of the side of the stone making it lifeless in comparison to a well proportioned cut.
  • If the Diamond is cut too shallow then the light will escape from the bottom of the stone and will not “sparkle” as much.

 

The Cut Scale

  • Excellent
  • Very Good
  • Good
  • Fair
  • Poor

You will hear the use of the word CUT used to describe the SHAPE of the Diamond .  As you can see below there are many different shapes of diamonds for you to choose from. The most popular shape is Round Brilliant or Princess Cut.  This part of the process is a matter of personal taste no one shape in particular is going to be better than the other, it simply comes down to your own personal taste.

CLARITY

  • Clarity refers to the amount of inclusions in the Diamond, the positioning and the colour of them.
  • There are clear inclusions, black inclusions, whitish or cloudy inclusions and they can vary in size.
  • Most Diamonds have inclusions in the stone that come about through the forming process in the earth. The smaller amount of inclusions in the stone the higher the clarity grading that particular stone will receive. This will also apply to the colour of the inclusion i.e. black or white and where it is located and the amount in the stone. Most of the inclusions in a Diamond are not visible to the naked eye and have to be seen by using a 10x eye glass or microscope.

Diamond clarity grading scale

Category Flawless InternallyFlawless Very Very Slightly Included Very Slightly Included Slightly Included Included
Grade FL IF VVS1 VVS2 VS1 VS2 SI1 SI2 I1 I2 I3
  • Flawless Diamonds with this grading have no inclusions visible.
  • Internally Flawless Diamonds with this grading have no inclusions internally but may have some imperfections on the Diamond surface.
  • Very Very Slightly Included Diamonds with this grading have minimal inclusions that are not easy to see under a 10x magnification tool. You will not be able to see any imperfections with your naked eye.
  • Very Slight Included Diamonds with this grading have minimal inclusions that are somewhat easier to see with a 10x magnification tool. You will not be able to see any imperfections with your naked eye.
  • Slightly Included Diamonds with this grading have noticeable inclusions and will be easy to see with a 10x magnification tool. You may be able to see this imperfection with your naked eye but it is highly unlikely.
  • Included Diamonds with this grading have very noticeable inclusions and will be easily seen both under 10x magnification tool and the naked eye. They can also be referred to in Australia as P1 clarity.

Note that V VS through SI have 2 gradings and in some cases will have 3 gradings on the particular clarity. i.e. V VS1, V VS2 or V VS3. As there is not a high enough amount of imperfections to take it to the lower grading level, it is not low enough to satisfy the higher grading level. The amount of inclusions will dictate to a certain degree the dollar value of the Diamond.

CARAT SIZE

The Carat size of the Diamond means how much the Diamond weighs.

  • A Diamond is broken down into points, there is a 100 points in a 1 carat Diamond written as 1.00ct.
  • Therefore if the Diamond you are looking at is a 1/2 carat that means there is 50 points of Diamond weight in that stone. It will be written as 0.50ct. meaning it is 50 points or half of 1 carat and will be referred to as a 50 pointer.
  • Similarly if the Diamond is a 3/4 carat then there is 75 points of Diamond weight and will be written as .75ct meaning it is 75 points of a full 1 carat and will be normally referred as a 75 pointer.
  • A 1/4 carat Diamond is 25 points of a Diamond weight and will be written as .25ct meaning it is 25 points of a full 1 carat and will normally be referred as a 25 pointer.

Diamonds are available in all sizes.

It is important to note as we discussed earlier, the Cut of a Diamond and the correct proportions will play a big part on the weight of a Diamond. If it is not cut correctly i.e. shallow but wide across the table (the top of stone) this will give the Diamond a different weight than a stone cut in the correct proportions of the same perceived size.

COLOUR

The colour of a Diamond actually means the lack of colour in the Diamond i.e. the whiter or clearer (colourless) the stone, the better the grading and the higher the cost of the stone. These gradings from one colour to the next is so slight that to the untrained eye it is not easily seen. What you will notice is the colour difference from say, a G to J and as you can see below there is nearly no yellow tinting in the G but it is very noticeable tinting in a J. This is why it is very difficult to compare apples to apples when you go from Jeweller to Jeweller.

  • Diamond colour grading starts with a D and runs through to Z.
  • Colour in a Diamond shows itself in the form of a yellow tinge moving into a light brown colour, the further you go down the Diamond Colour Scale. ( Not to be confused with a Cognac Colour Diamond which is grade on a different scale of C1 to C7)
  • Colour is the 2nd most important characteristic of determining what Diamond you want to purchase.

Diamonds also come in rare colours such as:

  • Pink (Argyle) sold at Richardson’s Jewellers
  • Yellow (Not tinted as mentioned above)
  • Blue
  • Green
  • Cognac or Champagne

All of the coloured Diamonds are graded in a different format than what is mentioned above and if this is something you are interested in, we suggest you come in and talk to one of our friendly staff in regards to getting a coloured Diamond. Please know that the pricing structure of Coloured Diamonds is much greater.

CERTIFICATE

Certified Diamonds are Diamonds that come with a Diamond Grading Report and are certified by a gemologist with the correct qualifications. The Diamond is graded and measured under a microscope for such things as:

  • Colour of the Diamond
  • Clarity of the Diamond
  • Polish of the Diamond (Light that is able to pass through the Diamond)
  • Symmetry of the Diamond ( Shape and facets of the Diamond)

COST

As you have learnt from all the information above there are several major characteristics that will determine your cost. As the Diamond market in Australia is determined by the US and AUD dollars, it is imperative that the prices we give you at Richardson’s Jewellers are based on what is happening in the market place worldwide.
