Our guide to buying your Diamond

Purchasing a Diamond is an incredibly exciting and nerve racking process. With the vast amount of information now available it can be difficult to understand what everything means and what Diamond to choose. 

 

You may have already heard of the 4 C’s; these are the most important elements that define a Diamond and affect the overall look, feel and price of each stone. We believe that this can be one of the most important decisions of your life, so here at Pugata we have put together a guide to help you through.

 

But first what is a Diamond? A diamond is the only gem made from one single element – Carbon. It is formed under extremely high temperatures and pressures that exist around 100 miles beneath the earth’s surface. As the carbon is exposed to these conditions it crystallises to form a perfect clear octahedron which is then transported to the surface via kimberlite pipes. Once it has been mined it is then transported to a highly-experienced diamond cutter who proceeds to turn the rough gem into the magnificent piece we know and love. 

diamond cut

Once a diamonds shape has been determined we must look at the other aspect of the Cut. This is in essence how well the stone is proportioned and well the position of the facets have been placed on the diamond. When light passes through a diamond it is returned back to our eye and we see a range of different things.

The most important are:

  • Brilliance – The white light that we see when looking at a polished diamond face up.

  • Fire – The coloured light that we see when looking at a polished diamond face up.

  • Scintillation – The overall appearance of light when the diamond, light or we move. As well as the contrast of the Fire & Brilliance pattern which is formed when looking at a polished diamond face up.
     

If the diamond is cut poorly the light will pass through the stone and not be refracted back to our eye. This will mean your Diamond will look dull and lifeless. If however it is cut well then the light will be returned back to us and we will see the sparkle and life that we want in our Diamonds. Below is an example of how light passes through a Diamond. 

There are five different grades to the Cut of the Diamond and they are as follows:

  • Ideal or Excellent Cut – The cream of the crop in cuts, rare to find these diamonds are exceptional in quality and reflect almost all the light that enters it.

  • Very Good Cut – Almost the same amount of light is reflected as an Excellent cut but these Diamonds have a slightly better price.

  • Good Cut- This reflects most of the light, and to the untrained eye looks as beautiful as either the Very Good or Excellent cut however it is much more affordable.

  • Fair Cut– This typically reflects only a small portion of light however it is still considered to be a good quality of diamond. Fair cuts are used to maximise total carat weight over anything else and can be great value for money.

  • Poor Cut– This is where the diamond has been cut too deeply or too shallow, it loses significant amounts of light and is dramatically cheaper in price than any of the other diamond grades.

The shape of the stone and the final cut can affect the price you pay for a stone. If you are unsure about which shape or cut is best suited for your budget then please do not hesitate to speak to one of our Gemologist for advice on which stone to select.

Diamond Carat

When Diamonds first began to be weighed they were measured against the Carob Bean and the term “carats” was given to the final weight. Then 1.00ct weighed the same as one Carob bean or the equivalent to 0.2grams but what is carat or ct?

 

The Carat weight is the overall weight of the diamond, One Diamond Carat is shown as 1.00ct and can be divided up into 100 points. You may have heard the term a quarter carat or a half carat, these relate to the amount of points the diamond weighs e.g. 0.25ct or ¼ carat diamond. There are special carat weights which demand a higher price, for example buying a diamond which is exactly 1.00ct can be much more expensive than buying a diamond which is identical in every way except it weighs 0.97cts.

 

The weight of the Diamond should not be confused with the measurements of the stone, there is a correlation and a rough estimate of weight can be gained by measuring the stone but it is not the only factor to affect the overall weight. Below is a chart which can help give examples of weight and measurement – as a rule of thumb the larger the diamond the more valuable but don’t forget the other 3 C’s can affect the price. If you are unsure on what size to buy then please do not hesitate to speak to one of our Gemologist for advice on which stone to select.

 

Please note that this chart is not too scale and can differ depending on your screen size and resolution etc. 

Diamond Colour

In this instance, Diamond Colour is the term used to describe how colourless the Diamond is. It is not to be confused with Fancy Coloured Diamonds which are Diamonds containing other elements aside from Carbon.

 

Diamonds are colourless unless they have the presence of an additional trace element which can make them red, yellow, green or blue as well as many other colours – these are known as Fancy Coloured Diamonds. Colourless Diamonds are also known as White Diamonds, but why are some white and some a shade of yellow?

 

When a Diamond forms there can be all sorts of natural occurrences which can affect its growth, for example if the earth shifts it can change the direction that the crystal lattice structure was forming and this in turn can affect the way the light is refracted, thus making it more yellow the clear.

 

When we grade a Diamond for colour we use a set of Diamonds called the “Master Stones”. 

Diamond Clarity

The term Clarity is used to describe the presence or absence of inclusions within or on a Diamond. The Diamond clarity can have a huge effect on not only the look of the Diamond but also the price and is crucial when choosing your diamond.

 

Inclusions within a Diamond are natural imperfections which can be anything from crystals of all shapes, size and colour through to small feather like fractures and clouds. When grading these inclusions, we need to look at the factors behind them which will affect the final grade result. They are as follows:

  • The amount of inclusions.

  • The size of the inclusions.

  • The nature of the inclusions.

  • The position of the inclusions.

  • The colour of the inclusions.

Each factor is examined under 10x magnification and assessed to give the appropriate grade. The categories listed below can affect the look and price of your piece:

  • FL-IF = Flawless or Internally Flawless. No internal inclusions.

  • VVs1-VVs2 = Very Very Slightly Inclusions. Very difficult to detect under 10x magnification.

  • Vs1-Vs2 = Very Slight Inclusions. Can be seen under 10x magnification and in some cases the naked eye.

  • Si1-Si2 = Slightly Included. Can be seen under 10x magnification and can be seen with the naked eye.

  • I1, I2 & I3 = Imperfect. Inclusions are very clearly visible under 10x magnification and with the naked eye. 

The most expensive diamonds fall into the top 3 categories, but it can be very difficult for the untrained eye to tell the difference between the top 4 categories. At Pugata we only use Diamonds from FL – Si1 with our standard Diamonds being between Vs1-Si1. The diamond clarity can affect the price so if you have a budget then please do not hesitate to speak to one of our Gemologist for advice on which stone to select.

The 5’th C - Certification

Having gone through the 4 main important points to look at when buying a Diamond, you will be ready to buy your dream piece. There is however one last thing to take into consideration when purchasing a special stone and that is Certification.

 

A Certificate is a document which lists all the important parts of the diamond in an easy to read manner. There are many Diamond grading houses around the world which offer these certificates but by far the best and most trusted is the Gemological Institute of America, or the GIA. The GIA have been established for over 85 years and is an organisation which protects all buyers and sellers of gemstones by establishing and maintaining the standards used for evaluating Diamonds & Gemstones. 

 

The GIA certificate is a fantastic addition to any piece of jewellery that you purchase and is a great way to identify your Diamond. Below is an example of one of the Certificates which we provide from the GIA for our certified stones.

These GIA Certificates are not able to be replaced if lost, stolen or damaged. However if you have a record of your GIA number you will be able to download a PDF file from the GIA Report Checking page.

 

We also provide our own Jewellery Certificates with each piece of Pugata Jewellery that you purchase. These stunning Certificates come with your personal details, an in-depth description of the piece, an image and a valuation suitable for any insurance company. 

If for any reason your certificate is lost, stolen or damaged then please let us know and we will be able to replace it for you for £25.00.

 

It is also advised that your jewellery is regularly valued and updated, for more information please contact our customer service team for more information.
