Choosing an engagement ring.

The smart groom-to-be does his research before buying his fiancée a diamond ring! There are more styles and cuts to choose from than ever before. It’s not enough to be educated about the four Cs of diamonds – cut, color, clarity and carats. Now there are all types of diamond cuts and settings to choose from.

The most popular style of engagement ring is still the round brilliant. It’s one of the earliest cuts ever developed and now relies on precise mathematical equations to create a stone with fire and brilliance that the earliest gem cutters could only have dreamed of.

But many brides want something completely unique. There are many traditional cuts to choose from. A pear-shaped is just that – wider at one end than the other. Or she can choose popular cuts such as an oval, emerald or heart-shaped diamond. There are other cuts with unique faceting, such as the square princess-cut diamond which is probably the second most popular cut.

Some cuts are patented, like the elongated Ashoka diamond or the Asprey & Garrard Eternal cut diamond. Other branded and patented cuts include:

Elara – a square-cut diamond with rounded corners

Asscher – a square diamond with rounded facets that gives an unusual complexity to the diamond

Couples diamond – this diamond is faceted to reveal either a circle of hearts or arrows inside. It’s a truly unusual diamond that requires precise cutting for the image to appear properly.

The price of a diamond increases exponentially with its carat weight. A one-carat diamond costs much more than 10, 10-point diamonds and a two-carat diamond costs more than twice as much as a one-carat diamond (given equal quality in other areas).

One way to enhance an engagement ring is with embellishments such as baguettes or trillions. A baguette is a small emerald-shaped diamond that can be placed on either side of the main stones and a trillion is a triangle-shaped diamond that also is a good enhancement to the center stone.

 

What To Look For When It Comes To Diamond Quality !

 

If you want to begin judging diamond quality, you must first learn and understand the 4 C’s, which are four characteristics of diamonds that give the gemstone it’s overall value.  The 4 C’s for judging diamond quality include the diamonds colour, clarity, carats and cut.

 

Judging Col0ur

 

Most diamonds are considered to be ideal if they are transparent, or colourless.  Diamonds that are rated as colourless are the most expensive of diamonds.  The colours of diamonds are rated with an alphabet grading system that starts with “D” and ends with “Z”.  Completely colourless diamonds fall in the “D” and “E” grade, while coloured, fancy diamonds are at the other end of the alphabet, at “Y” and “Z”.

 

There are two main ways that jewellers’ use when judging diamond quality based on colour.  They may pull out a set of reference stones, and find the closest match between the diamond and the reference stone to determine its letter grade.  Alternatively, the jeweller may use a colorimeter, which can electronically measure the colour of the stone and determine its grade within 1/3 of a grade.

 

Judging Clarity

 

The clarity of a diamond refers to whether or not the diamond is clear all the way through, or whether it has tiny flaws and cloudy areas within the gemstone.  It’s actually very rare to have a diamond with absolute perfect clarity and no flaws, but most diamond flaws are not visible to the naked eye and can only be seen with a magnifying device.

 

The Gemmological Institute of America (GIA) uses a magnification of about 10x when judging diamond quality based on the clarity.  It is important to do your research before purchasing a diamond to be sure you are not spending more money than you should.

 

Judging Carat Weight

 

Carat is the term we used to describe the weight of a diamond gemstone.  One carat is equivalent to 200 milligrams of weight.  A single diamond with a high amount of carat weight is more expensive than the equivalent amount of carats in multiple stones.  This is because finding the larger diamonds is much more rare of an occurrence.  So if you want a 2-carat diamond ring, for example, you may decide to go with a half-carat diamond surrounded by smaller diamonds that add up to one and a half carats to give you the total of 2 carats!  Judging diamond quality by the amount of carats is difficult, since different shaped gemstones, and stones with different levels of clarity will be priced differently even if they have the same amount of carats.

 

 

 

Judging Cut

 

One of the most important factors in judging diamond quality is judging the cut of a diamond.  It’s important because a quality cut diamond will be more brilliant and reflects light more beautifully, and yet the cut of a diamond has the least impact on the overall price of the diamond.

 

When judging diamond quality on the cut of a diamond, look at the stone in a well lit area.  If the light seems to go into the stone and bounce back, showing a sparkling reflective surface, the diamond has a good cut.  The angles and shapes of a diamond are important to judging diamond quality and the overall appearance of your diamond.

 

There is much to consider when purchasing a diamond – especially diamond engagement rings! The tradition of presenting a woman with a diamond engagement ring when proposing began in 1477 when Archduke Maximilian presented a diamond ring to Mary of Burgundy – and in most cases, the woman you plan to propose to will expect a ring to accompany that proposal!

First, determine how much you can afford for the ring . Most people use the ‘two months salary’ rule. This means that the ring should cost the equivalent of two months of your current salary. Because you have other bills to pay, saving up this amount of money may take quite a bit of time. You should consider financing. Simply go to the jeweller of your choice and tell them that you plan to buy an engagement ring, and that financing will be necessary. Go ahead and get the credit check out of the way, find out what your payments will be, and how much of a down payment is required.

Now, have your mother, sister, or your girlfriends best friend take your girlfriend shopping, and make sure that they gaze at the engagement rings to get an idea of what she might like. Make sure that the jewellery store you buy the ring from will allow you to exchange the ring, if that is required so  your girlfriend can exchange it for another if she isn’t happy with it! Most jewellers will not give a refund but will allow an exchange for a ring of equal or more value !

Diamond Grading, Grades

When purchasing certified diamonds it is important to understand the diamond grading criteria used by the laboratories performing the certification.

Diamond grading covers numerous aspects of each individual diamond’s qualities, but there are four grades which are critical to understand: cut, clarity, color, and carat weight. There are additional ratings and measurements noted on a diamond certificate, but they generally fall under the diamond’s grade in one of the Four Cs. For example, measurements listed such as “depth” and “table” are part of the description of the diamond’s cut.

You can learn more about how diamonds are graded by reading the articles listed below.

Diamond Cut

Cut is probably the most important quality factor, and most challenging, of the four Cs to understand. The brilliance of a diamond depends heavily on its cut. More info…

Diamond Clarity

Most diamonds contain some inner flaws, or inclusions, that occur during the formation process. The visibility, number and size of these inclusions determine what is called the clarity of a diamond. Diamonds that are clear create more brilliance, and thus are more highly prized, and priced. .

Diamond Color

Colourless diamonds are the most desirable since they allow the most refraction of light (sparkle). Off white diamonds absorb light, inhibiting brilliance.

Carat Weight

A carat is the unit of weight by which a diamond is measured. Because large diamonds are found less commonly than small diamonds, the price of a diamond rises quickly as its size increases.

 

The larger a diamond the more expensive it is and as we rise up the scale of size the prices rise dramatically. There are key price points 0.25,0.5,0.75,1.0,1.25,1.5,1.75.2.0,2.5.3.0,3.5,4.0,4.5,5.0.The reality is that a 0.97 carat can be a lot cheaper than a 1 carat. People often like to be able to have an exact number a 1 carat weight is a key point. In the business we often refer to an 80 pointer which means 0.8 of a carat or we may refer to a stone as being a one fifty which means that it is one and a half carats.

The Fifth C: Certificates

The diamond certificate, which is sometimes called a grading report, is a complete evaluation of your diamond that has been performed by a qualified professional with the help of special gemological instruments. Each stone bears its own recognizable, individual characteristics, which is listed on the certificate. The most recognised certificate in the business is the GIA certificate. The IGI and HRD are also widely recognised and highly thought of.

There are various other certificates around but the bottom line is if you buy one of the above it will be exactly what it says on the certificate!!The EGL certificate has not got the greatest reputation and should be treated with great caution. We will not accept anything we read on an EGL cert unless we verify it independently with our gemologist. Having said all that EGL certed stones are cheaper and the odd bargain does come through.

There are also some uncarted stones which doesn’t mean they are bad –some manufacturers simply want to turn the stone around quickly and are doing so in high volumes and hence the stone is uncerted. This is often the case in smaller stones of less than one carat.

The reality in larger more valuable stones is that they should be certed and there is no reason that they should be offered uncerted.
