The quality of diamonds is measured all around the world by these 4 standards.
CUT: Of the 4 C’s cut has the greatest effect on a diamonds beauty. You know that unmistakable ‘SPARKLE’ of a diamond? The better and more precisely it is cut, the more light is reflected from its facets and the more dazzling it appears to the eye.
CLARITY: Most diamonds have small internal flaws called inclusions. It is rare for a diamond to be found with no inclusions although they may not be visible to the naked eye. The less and the smaller the inclusions – the more valuable the diamond.
COLOUR: Although referred to as ‘white’, traditionally the best quality diamonds have no colour. Like a drop of pure water. Have you noticed that coloured diamonds including yellow, brown or chocolate, red and pink have gained in popularity lately? Magnificent pink diamonds are extremely rare and are very expensive.
And now to our favourite – carrots. OOPS – make that …
CARATS: Sometimes mistaken for size, the carat is actually a weight relating to diamonds. A metric ‘CARAT’ weighs 200 milligrams. And just as a dollar can be divided into 100 cents, a carat can be divided into 100 points. For example a 50 point diamond = ½ a carat.
At Flair Jewellery we like to add our own ‘C’ to the other 4 – CONFIDENCE. Come in to one of our shops and one of our qualified tradesmen will gladly talk you through the information above and take the time to show you the difference in the quality of various diamonds, which is sometimes tricky to spot.
We hope you have enjoyed reading about the 4C’s when it comes to diamonds. We are proud of our own “C” – CONFIDENCE. We are confident that you will walk away brimming with confidence! Come in and see us or contact us!
Many people are confused about how diamonds are priced. The best explanation is that asking for the price of a diamond is like asking for the price of a house. A real estate agent can’t quote you a price for a house without knowing its size, condition, location, etc. This process is the same one used when buying a diamond. A diamond’s beauty, rarity and price depend on the interplay of all the 4Cs – cut, clarity, carat and colour.
The 4Cs are used throughout the world to classify the rarity of diamonds. Diamonds with the combination of the highest 4C ratings are more rare and, consequently, more expensive. No one C is more important than another in terms of beauty and it is important to note that each of the 4Cs will not diminish in value over time.
Once you have established those 4C characteristics that are most important to you, we can then begin to show you various options and prices.
Refers to the weight of a diamond.
Carat is often confused with size even though it is actually a measure of weight. One carat is equivalent to 200 milligrams. One carat can also be divided into 100 “points”. A .75-carat diamond is the same as a .75-points or ¾ carat diamond.
A 1-carat diamond costs exactly twice the price of a half-carat diamond, right? Wrong. Since larger diamonds are found less frequently in nature, which places them at the rarest level of the Diamond Quality Pyramid, a 1-carat diamond will cost more than twice a ½-carat diamond (assuming colour, clarity and cut remain constant).
Cut and mounting can make a diamond appear larger (or smaller) than its actual weight. We can help you to find the right diamond and setting to optimize the beauty of your stone.
Refers to the presence of inclusions in a diamond.
Inclusions are natural identifying characteristics such as minerals or fractures, appearing while diamonds are formed in the earth. They may look like tiny crystals, clouds or feathers.
To view inclusions, jewellers use a magnifying loupe. This tool allows jewellers to see a diamond at 10 times its actual size so that inclusions are easier to see. The position of inclusions can affect the value of a diamond. There are very few flawless diamonds found in nature, thus these diamonds are much more valuable.
Inclusions are ranked on a scale of perfection, known as clarity, which was established by the Gemmological Institute of America (GIA). The clarity scale, ranging from F (Flawless) to Included (I), is based on the visibility of inclusions at a magnification of 10x.
Some inclusions can be hidden by a mounting, thus having little effect on the beauty of a diamond. An inclusion in the middle or top of a diamond could impact the dispersion of light, sometimes making the diamond less brilliant.
The greater a diamond’s clarity, the more brilliant, valuable and rare it is – and the higher it is on the Diamond Quality Pyramid.
For more technical information on clarity, see the diamond-grading chart.
Refers to the degree to which a diamond is colourless.
Diamonds range in colour from icy winter whites to warm summer whites. Diamonds are graded on a colour scale established by the Gemmological Institute of America (GIA), which ranges from D (colourless) to Z.
Warmer coloured diamonds (K-Z) are particularly desirable when set in yellow gold. Icy winter whites (D-J) look stunning set in white gold or platinum.
Colour differences are very subtle and it is very difficult to see the difference between, say, an E and an F. Therefore, colours are graded under controlled lighting conditions and are compared to a master set for accuracy.
Truly colourless stones, graded D, treasured for their rarity, are highest on the Diamond Quality Pyramid. Colour, however, ultimately comes down to personal taste. We can show you a variety of colour grades next to one another to help you determine your colour preference.
Refers to the angles and proportions of a diamond
Based on scientific formulas, a well-cut diamond will internally reflect light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing well-cut diamonds higher on the Diamond Quality Pyramid than deep or shallow-cut diamonds. Diamonds that are cut too deep or too shallow lose or leak light through the side or bottom, resulting in less brilliance and ultimately, value.
Cut also refers to shape – round, square, pear or heart, for example. Since a round diamond is symmetrical and capable of reflecting nearly all the light that enters, it is the most brilliant of all diamond shapes and follows specific proportional guidelines.
Non-round shapes, also known as “fancy shapes”, will have their own guidelines to be considered well cut.
What to Spend
When you start to think about buying a diamond – and the love it will symbolise – you naturally want the best you can afford and a beautiful stone you will treasure forever.
Diamonds can be found in a range of prices – and you’re certain to find one that suits your taste and what you plan to spend. If you’re about to buy a Diamond Engagement Ring, you may want to consider spending the commonly accepted guideline of two months’ salary. But it’s up to you to settle on a diamond that will truly represent your deepest emotions and the promise for the future you will share.
