THE FOUR C's:

Cut

Cut is a very important quality factor, and probably the most challenging, of the four Cs to understand. The brilliance of a diamond depends heavily on its cut, which give a diamond that brightness that seems to come from the very heart of the diamond. The quality of the cut is a result of just the right angles, proportions and finish of the diamond.  It is the quality of the cut that gives a diamond its ability to handle light, which in turn leads to its dazzling brilliance and fire.

Clarity

Almost all diamonds contain some inner flaws, or inclusions, that occur during the formation process.  These inclusions are the ‘birthmarks’ of the diamond.  The visibility, number and size of these inclusions determine what is called the clarity of a diamond. The inclusions interfere with the path of light through the diamond and therefore, diamonds that contain a lower degree of these inclusions create more brilliance.  The better the clarity of the diamond the more expensive the diamond will be.  Most inclusions in a diamond are so small that it is not possible to see them with the naked eye.

Color

A diamond is graded based on its lack of colour.  The less colour, or the more colourless a diamond is, the greater its value and its visual appeal. Diamond colour grades range as follows:

• D-F (Colourless) – These are the rarest and highest colour grade diamonds
• G-J (Near Colourless) – These are rare diamonds still with a bright white colour
• K-M (Faint) – These are not so rare diamonds with a slight yellow tint
• N-R (Very Light) – These are widely available diamonds with noticeable yellow tint
• S-Z (Light) – These grade of diamonds are plentiful in the market and therefore the lowest colour grade

Colourless and Near Colourless diamonds are the most desirable since they allow the most refraction of light (sparkle). 

Carat (weight)

Diamond Carat is the unit of weight by which a diamond is measured  As diamond carat weight increases so does its value, however it is important to note that as larger diamonds are rarer than smaller ones, the value of a single diamond increases exponentially with its carat weight.  Often the carat weight of a diamond is used when talking about the diamonds size.  Although this is not strictly correct, naturally, as the weight of a diamond increases, so does its size, and for this reason people use Carat weight as an indication of size. 

The table below shows the approximate diameter of a round and princess cut diamond as the carat weight changes:

A Super Sparkling look at the World of Sapphires

The world of precious gems is both intriguing and beautifully varied, and there may be few as well placed an example of this as the world of sapphires.

So here we take a look at the sapphire stone and take time to appreciate just what this jewel brings to the sparkling work of gems.

Sapphires - A few famous fans

A right Royal story:

Kate Middleton, the Duchess of Cambridge is known as one of the most famous celebrities to wear Sapphires. Her engagement ring was, of course, first worn

by Princess Diana and consists of 12 solitaire diamonds and a 12-carat oval sapphire set within 18-carat white gold.  When purchased originally in 1981 the

ring was worth £28,000; today however, with its extensive royal connections, it is now worth an estimated £300,000.

Anna Kournikova rocks the pinkest of sapphires:

Anna Kournikova demonstrates just how beautiful the pink sapphire can be as she wears her £2 million engagement ring (from Enrique Iglesias, no less)

everywhere, even on the tennis court.

The story behind the scenes of Titanic and that ‘Heart of the Ocean’ necklace:

There were two ‘Heart of the Ocean’ necklaces used within the filming of Titanic… one that was designed and created by Harry Wilson, which featured a blue

sapphire as well as a $20 million price tag, and another which featured a 12-carat blue diamond which cost a comparatively measly $10,000.

Sapphires: Just where do these beautiful jewels come from?

In comparison to other gems, Sapphires are relatively diverse in relation to the regions of the world that they are mined from. In the main, these stones come

from the following countries (although this is by no means a complete or all-encompassing list): Afghanistan, Australia, Myanmar/Burma, Cambodia, China,

Colombia, India, Kenya, Laos, Madagascar, Malawi, Nepal, Nigeria, Pakistan, Sri Lanka, Tajikistan, Tanzania, Thailand, USA, and Vietnam.  The sapphires that

are found from one region or country to another can be wildly different in qualities and appearance. For example, in Beluga, sapphires tend to have a distinctive

deep blue colour with violet overtones, whereas Afghanistan and Pakistan offer stones that are more tourmaline or aquamarine in tone.

A little technical information upon the Sapphire gem

A few general notes on sapphire value

The most valuable of all sapphires are those that are cornflower blue (which tends to mostly emerge from Sri Lanka). As a general rule of thumb however,

focusing upon the deepness of the colour and the clarity of the stone will provide you with a good base upon which to work, whatever the colour of the sapphire

(which may actually be White, Colourless, Blue, Green, Yellow, Orange, Brown, Pink, Purple, Gray, Black, or Multi-coloured).

The hardness of the stone

Like many gemstones, Sapphires can range in hardness, and are defined by a 9 step scale where 1 is the softest and 10 is the hardest. This denotes how

susceptible the stone may be to scratching, with the softest being most prone and the hardest least prone.

The three components of a sapphire: Hue, saturation and tone

When purchasing sapphire gems, there are three qualifying components that will determine the gem’s value. These are hue, saturation and tone:

-          Hue is more commonly understood as the colour of the gem;

-          Saturation is the vividness of the stone;

-          Tone is the range of light to dark within the colour of the gem.

Blue Sapphires: The true jewel within the Sapphire world’s crown

Most of us will conjure up an image of a blue stone gem as soon as the word ‘Sapphire’ is mentioned and, whilst sapphires feature in many colours, it is often the

blue sapphire that is considered to be the most beautiful, as well as accounting for some of the most valuable in the world. The blue sapphire is the birthstone of

September and is known to represent serenity and loyalty; they are frequently given as a gift to brides as their something blue on their big day.

Evaluating the worth of a beautiful deep blue sapphire - Blue sapphires are evaluated based upon the pureness of what is known as their primary hue; purple,

violet and green may all then serve as the secondary hues within the stone, with violet and purple contributing to a rich blue, and green generally detracting from

the overall effect. Because of this, green hue based sapphires are considered to be of lower quality than those that are violet or purple based.
