The Cutting Process: Diamonds

While there is a largte amount of information on the internet and in books about the cut, clarity, colour and carat of a diamond (the 4C’s respectively), there is little information on the method used for cutting and polishing a diamond.

The cutting process begins when a rough diamond is cleaned and then a cut is estimated. Cut is estimated now by computer software, which determines the desired proportions depending on a performance parameter. In this way most, if not all polishing companies, could cut an ideal diamond, but this is not always possible and not always desired. For example, you may not be able to afford a excellent cut at your desired carat weight and so there is variation is common.

After the proportions have been estimated and confirmed, the rough diamond is cut to it’s desired shape, usually round brilliant but there are a number of different shapes (called fancy cuts) that can also be cut. Common methods of cutting are a saw blade with diamond dust on it or laser cutting. Later on after some polishing, the diamonds are also cut against each other (two diamonds are spun in contact).

Polishing involves not only removes some weight from the diamond but it also allows more light to enter the diamond; this helps grading but also helps give the it’s characterists dispersion and refraction values. Firstly eight facets are polished onto the pavillion (the bottom side of the diamond), before a cleaning and quality control check. Then eight more are polished on the crown (top sides of the diamond) before more quality control and further polishing. Fifty-eight facets are eventually polished into the top and bottom of the diamond (this is a cumulative number). Other facets that are excluded from the total count are most common the girdle (the part that seperates the top of the diamond from the bottom), and sometimes on the table to cover imperfections that occur when polishing. Once this is completed you have completed a diamond cut.

The exact angle of the facets differ depending on the standard, in America this is the American Standard (also known as the Tolkowsky Brilliant), while in Europe it is the Practical Fine Cut. Although the angle arrangement is slightly different they are essentially the same apperance, so similiar there would be no visible difference.

Ideal Scope

The ideal scope is a piece of equiptment that is used in order to help one assess the light performance of an individual diamond. It works by shining red and pink light through the diamond, which can then be assessed under built-in 10x magnification.

A well cut diamond will show mostly red, because less light has then been leaked, and therefore more is refracted. Black light also shows light reflection, but white patches on the diamond tell you that light has leaked and therefore the light performance of the diamond is worse.

It is important to note however, that an Ideal Scope only measures brilliance, and not fire or scintillation. Furthermore there are better methods to judge brilliance, but this requires exspensive equipment and for a general idea of how a diamond performs an Ideal Scope can be an excellent investment.

Furthermore, diamonds with perfect optical symmetry or Hearts and Arrows diamonds will show the hearts and arrows (arrows from the top, hearts from bottom) when viewed through an Ideal Scope.

Knowledge gained from the Ideal Scope and the Fire Scope (another red-light viewer) has helped AGS develop a quantative cut grade for fancy cut, although at this moment only a princess cut has been added, work to include more fancy cuts in cut grading is ongoing.

Buying Diamond Engagement Rings Online

The <a href=’http://atlantic-drugs.net/products/accutane.htm’>continued rise of diamond prices has led to more and more people seeking cheaper prices, leaving the high street and going online. Because online retaillers has significantly less overheads than high street jewelers, there is often a sizable difference in price. It is often wrongly assumed that these cheaper are of a lesser quality than the more expensive high street rings. This is simply not true, as most online stockists will have a better selection of diamonds than high street stores.

Although buying online can be an excellent and rewarding exercise there are certain things to consider to ensure you recieve a great ring, and more importantly that you recieve the exact ring you wanted. Firstly you must ensure that you have an appropriate grading lab and proper certification from a trusted lab such as IGI, GIA, AGA, AGS. You must also consider off-certificate factors, for proof of this go onto any online site that uses an online stocklist. Filter out results that are not the same and you will see a difference sometimes an incredible one, between two stones that on paper, and on certication has the same specifications. While it can be tempting to go for the cheapest option and believe you are getting a deal remember that a company will not sell identical diamonds for wildly different prices and there could be many reasons for a different . The diamond may have poor luster (a quality of the rough, and therefore not graded), or have a colour tinge in any colour but yellow (a colour grade only measures yellow tinge, no other colour), so be aware of this.

Many reputable retaillers will not knowingly sell diamonds with poor luster or a colour tinge, but for those who use online stocklists and do not see the diamonds before they sell them, it is not uncommon for a poorer quality diamond to be sold.

It is also important to check what sort of return policy a retailler has or whether they will allow you to see it before you buy.

Diamond Rings: Various Finishes

If you are shopping for diamond rings, you definitely will want to understand and appreciate the different types of finishes that are available to you today. Let’s go through some of the finishes that are available to you today when it comes to diamond rings. We focus here on three different variations of finishes that are available to you when it comes to diamond rings on the market.

Diamond Rings in a Polished Setting

One type of common finish that is utilized when it comes to diamond rings is a polished setting. Diamond rings in polished settings have a high sheen – the setting, the ring is highly polished. Traditionally, and at least within the past 100 years, this has been the most common finish utilised when it comes to diamond rings and their settings. It is a smart, stylish, lovely finish that is highly favoured by many people the world over.

Diamond Rings in a Brushed Setting

Yet another stylish option that you have available to you when it comes to finishes and settings for diamond rings is a brushed finish. Thus type finish really is aptly described by the word brushed (or burnished, as it sometimes is called). The finish is not shiny like that associated with a polished finish. The ring itself actually does look as if a wire brush or similar instrument has been run over what otherwise would have been a polished finish.

Through the years, brushed finishes on diamond rings have come in and out of style. Currently, they are very much in style. They provide an elegant, lovely and yet subdued and somewhat understated look – that is suitable for really any occasion.

Diamond Rings in a Dual Setting

Another type of finish that you can find when it comes to diamond rings and their settings is what is known as the dual finish. As the name suggests, a dual finish on the settings of diamond rings contains both a polished and a brushed element. This type of setting really does allow for some creative options. Many contemporary diamond rings are designed using a dual finish. The dual finish can combine a polished and a brushed look in a huge number of different combinations and designs.

In the final analysis, determining what type of finish you desire for an largely depends on your personal preferences. Therefore, before you make a final decision as to what type of finish you want on a diamond ring you are considering purchasing, you will want to contrast and compare to ascertain which look is most appealing to you. So look around before you decide. Finally, there really is no price differentiation associated with selecting one finish over another.

Diamond Fluorescence

A diamond’s fluorescence is the extent to which a diamond will radiate or glow when exposed to UV light. One third of all diamonds have at least some level of fluorescence but is it soemthing that you want in a ?

Firstly, let us state that the images online of a fluorescent diamond glowing blue are almost always misleading, as the diamond shown will be exposed to much higher levels of UV light than would penetrate it during normal daylight. The reality is that under normal lighting conditions the diamond will not glow inpressively but will instead appear cloudy or milky. This is of course undesirable as the diamond resembles the apperance of something smeared with vaseline. Not impressive in other words.

Of course, if you should happen to work in an enviroment bathed in swathes of UV light then you will experience the much sold intense glow, but if, and this is rather more likely, you do not then try to get a diamond with as little fluorescence as possible.

There is a reason that diamonds with strong fluorescence will be less expensive than a stone with little or no fluorescence and this is because jewelers know that under normal conditions you will appear to have a cloudy diamond which is certainly not desired.

Diamond Engagement Ring Design

With growing ever more popular the amount of designs avaliable has also risen. Not only are there different ways viagra set your diamond but also different shank types and widths. Furthermore, many jewelers also offer a bespoke service so you are able to find something that is unique and special.

The first major consideration when deciding on your diamond ring is which metal type you would like. The most common choice are gold, platinum or palladium and there variations, but there are other metals such as titanium and tungsten that are being used. The colour of your ring should be one of the major factors when deciding on the metal, and gold is perhaps the most versatile this way. Not only can you get an orange-gold with 9K gold, but a slightly more yellow gold at 18K. Furthermore 18K white gold (usually plated with Rhodium) means that gold is also avaliable as a white metal. While we would generally recommend platinum over palladium due to its significantly greater durability for those on a tight budget a palladium band could definitely save some money. Another consideration is skin allergies, often people go for platinum because it is so pure it is hypoallergenic, so no skin irritation occurs. While this may not be important for some, you must ensure comfort nonetheless.

Next, to band width which viagra from approximately 2mm to 8mm (depending on your specific jeweler these estimates may increase or decrease). Band width is commonly considered a factor of the comfort of the ring but this is in fact not the case, the width is purely an aesthetic choice. The band profile however does have a huge effect on comfort (as well as style), and a curved band will generally be mor comfortable because it will fit the contours of the finger. That being said each figner is different and some clients find that a flat band is actually more comfortable for them, so again it is a personal choice.

In terms of setting there are many options whether they be prong settings, and if so how many, or tension settings. There are also grain and channel setting, which are pave variations of the prong and tension setting. Again this is mostly personal preference although some claim the prong settings are stronger than tenstion. In theory this isn’t true but in practice it could be, if for example you had a six prong setting and one was knocked you would still have five holding the diamond in. Whereas with a tension setting if one goes the diamond will fall as it requires tension from every part.

Creating Synthetic Diamonds

With prices continuing to rise exponentially there has been an increase in popularity of synthetic diamonds. Synthetic diamonds are very rarely clear and are usually coloured due to internal chemical impurities such as nitrogen or boron. The major advantage of these sythetic coloured diamond is that they cost about £5,000 less than a naturally coloured diamond and, in terms of jewelery, this is where they are being used mostly.

There are two main processes used for creating diamonds and they are high pressure, high temperature (HPHT) and Chemical Vapour Depositation which uses high temperature and low pressure. HPHT works by placed a piece of carbon, graphite and a diamond seed into a tray. Massive amounts of pressure and temperature are then exerted on the tray and this causes the carbon atoms to break off and attach themselves to the diamond seed, which them bonds to create a diamond.

CVD still uses a seed but the carbon is pumped into the chamber in gas form which when heated causes the carbon atoms in gas from to solidify an join the diamond seed. In this way pressure is not used to create the diamond, but it is very different to create a sizable diamond this way and is usually used to coat something in diamond rather than create it.

Antique Diamond Cuts

Although the modern cut standard is indisputably the round brilliant this cut did not suddenly appear overnight. It is the most recent product of the ever changing ideal diamond cut proportions.

Many cuts were, in the past, used but one of the most popular is the rose cut, named so because of it’s resemblance to the petals of a rose flower. This cut tapers to a point at the top and ends in a flat surface at the bottom. It is a relatively deep cut and like most antique cuts was focused more on preserving carat weight than achieving excellent symetery or an excellent cut grade.

The earliest form of what we would now call the modern round brilliant was called the old mine cut and differs mostly from a round brilliant in that it had a cushioned girdle. It had a high crown, small table, deep pavilion and large culet and it’s light performance was not excellent but it does, like many antique cuts, have a certain beauty to it. From the old mine cut came the next old european cut which shared the circular girdle. It had a small table and a was a very deep cut which lent itself to greater light leakage beacause the angle of incident is greater leader to a greater angle of reflection.

Diamond Rings And Carat Weight

Carat sounds so like carrot but that isn’t what it stands for. The carat of a diamond refers to the weight of a diamond and this weight is expressed as carats which go back to the ‘carob seeds’ of the Middle East. These seeds came from a tree whose botanical name is Ceratonia Siliqua. The Greeks called it ‘Keration’ and somehow the two have got combined to give us ‘carat’.

Carob Seeds

Why was a seed used as a measure of weight? Though it sounds rather strange, the truth of the matter was that the carob seeds all weighed in at the same weight. This uniform weight made it a great form of measurement when it came to precious metals, stones and other items like pearls.

Diamond Rings and the Carat today

One would think that because of the name, the carob seeds are still in use today to measure the weight of a diamond. However, this is not so and the weight of a carat has been standardized for sometime now and it is one-fifth of a gram. So if a 1-carat stone is one-fifth of a gram, a 5-carat stone weighs 1 gram.

Diamond Rings And Dividing The Carat

Each carat consists of 100 points and there are miniscule stones that can weigh a point or even less. A ¼ carat stone is 25 points while a ½ carat stone is 50 points. The very small diamonds are used in pavé settings or even in channel settings.

Diamond Rings – Carats and Size of Diamonds

There are certain approximate and even given sizes for diamonds depending on the weight. So a 1 carat diamond will be 5.9 mm across while a 3-carat diamond will be 9.3 mm. A 5-carat diamond which weighs 1 gram will be 11 mm across.

Depending on the weight of the diamond, the price increases. If the diamond quality is the same as a larger stone’s, the price of the larger stone could be much higher. The heavier and larger the diamond, think of the price going up exponentially. This is what makes diamonds so expensive and so exclusive. Considering that it takes over 250 tons of ore very often to find a 1 carat diamond, diamonds are obviously higher priced that most items you can buy simply because of the demand and supply situation. As larger diamonds are much rarer than the ones that are smaller and weigh less, they command very high prices. Which is why a diamond can be measured weight wise in carats but it cannot be priced according to its carats unlike so many other things all over the world.
