We have access to over 1.5 million different loose diamonds worldwide.Loose diamonds as the term infers means that the diamond is not in a setting.

There are a great many reasons to buy a loose diamond.Some people like to give loose diamonds as a present so that the recipent can build a ring around the diamond.Loose diamonds can like any other diamond be certified or uncertified but we at International prefer to sell certified stones.

One might ask is there anything wrong with an uncertified loose diamond.The answer is sometimes no as the diamond can look on the face of it as good as any other diamond but often the mine will have decided that it is not going to make certain criteria and that these stones will be sold off at a discount.Sometimes an uncertified loose diamond can be available at a very substantial discount so do not rule them out.Most reputable dealers offering loose diamonds will offer to upgrade them to loose diamond later on when the finances improve.

Some people prefer to sacrifice quality for size and the trick is to find a happy medium when buying your loose diamond certified or not.

In the modern world diamonds can be transported quickly and we can get a diamond from most parts of the earth within days!Once a loose diamond has been found we can build a setting to fit around it and this is done by creating a CAD.CADS or Computer aided designs often look unattractive because of their sheer size.Do not let this put you off the designs have to be of scale in order for the cad operator to be able to see them properly.

Good luck with finding your loose diamond.We supply both loose diamonds and the complete ring and are happy to do either.

 

 

 

Have you ever looked at two different diamond engagement  rings each with the same size stone and felt one was bigger than the other? Well if you did you weren’t imagining that they were different-they were!

Diamonds spread in different ways so a little chubby  one carat diamond can look the same size as a well spread 0.80 carat diamond.Cutters given a choice will always aim for a target weight to maximise the value of a diamond.

One carat diamonds spread from about 6.0 mils to 6.5 mils so there is almost a 10 per cent differential.There is also a price differential the 6.0 mil stone will have been bought much cheaper than the 6.5 mil stone.A reputable dealer will explain the difference.

The good news is that a well spread 0.90 carat stone will look identical from the face down to the observer so a saving can be made.Always ask about diamond spread when looking for your GIA HRD or IGI certified diamond as it has a considerable effect on appearance when you are trying to create your perfect ring!

 

Lets us know if you have any queries.

 

Best wishes

A mineral composed essentially of carbon that crystallizes in the “cubic,” or “isometric,” crystal system and is therefore singly refractive. IT is by far the hardest of all known natural substances (10 on Mohs’ scale); only manmade Borazon and synthetic diamond are as hard. In its transparent form, it is the most cherished and among the most highly valued gemstones. It occurs in colors ranging from colorless to yellow, brown, orange, green, blue, and violet. Reddish stones are known, but those of an intense red color approaching that of ruby are excessively rare. Its hardness and high refractive index (2.417) permits it to be fashioned as the most brilliant of all gems, and its dispersion (.044) produces a high degree of fire. The specific gravity is 3.52. Sources include various sections of south, west, southwest and middle Africa; Russia; central, east and northeast South America; India; Borneo; and Australia. It is also found in the United State, but not in commercial quantity.

The world’s biggest diamond, believed to be twice the size of the Cullinan, has been discovered in the North-West Province of South Africa. The find has electrified the diamond community, but the circumstances of the discovery are shrouded in mystery.

The diamond is expected to attract furious bidding from buyers worldwide and could fetch up to £15m.

A spokesman for the mining house which made yesterday’s find, Brett Joli, said the diamond was being rushed to a bank vault in Johannesburg and would be kept there for a couple of days “until we calm down and decide what we are going to do”. A security company was being hired to protect the precious stone.

The mining company which made the find has not been identified.

The South Africa Broadcasting Corporation said the stone was said to be twice the size of the Cullinan diamond.

Fred Cuellar, the founder of Diamond Cutters International and author of How to Buy a Diamond, said he first heard about the find a few days ago. “I get a phone call when any rare stone around the world is found and when I heard about this one it was stunning news.

“It caught everybody in the diamond industry offside. There will be a lot of mad bidding from a lot of private individuals as to who is going to buy this stone.”

The Cullinan, which was found near Pretoria more than a century ago, was until recently acknowledged to be the largest cut diamond in the world, weighing in at 530.20 carats. In 1985 it lost the record to the Golden Jubilee, which was found in the same mine as the Cullinan and weighed 545.67 carats.

In its rough state the Cullinan weighed 3,106.75 carats. It now forms part of King Edward’s sceptre and is in the Tower of London.

The Cartier diamond, famous as a gift from Richard Burton to Elizabeth Taylor, weighed a mere 240.80 carats rough and 69.42 carats cut.

Mr Cuellar said the most important information about the latest find was yet to be forthcoming, including whether it is colourless. “The reported size of the stone is accurate, but there are all these other factors we still don’t know and what matters now is how wide, how clear and how well cut it will be.

“Will this diamond rank above the best quality diamonds in the world? I can tell you right now, no. But in as far as the list of the largest diamonds ever found in the world goes, would it make that list? Yes it would.”

He said the first seven people who looked at the stone thought it was industrial grade, but that view has changed and it now appears to be a stone that will be cut into a piece of jewellery.

The quandary facing the owner of the diamond now is how best to cut the stone he said. “The thinking usually is with these types of things, we know how big we could get it but we don’t know how much it will hurt us on the quality side.”

The Cullinan, also known as the Star of Africa, was thought by some to be part of a larger stone which still lies somewhere undiscovered.

There will be interest in who made the find and how they will be rewarded. The black miner who discovered the Excelsior, said to be the second largest uncut diamond ever found, received a horse and saddle, and a sum of money.

Rock stars

· The Cullinan Diamond was discovered in 1905 and at 3,106 carats was the largest gem-quality rough diamond ever found. Cullinan I, or the Great Star of Africa – at 530 carats formerly the largest cut diamond – was one of the 105 gems cut from it.

· The Koh-i-noor is part of the British crown jewels. It originated in India but seized by Britain as a spoil of war in 1849. The diamond supposedly brings good luck to female owners and misfortune or death to any male who wears or owns it.

· The Hope Diamond is a large (45.52 carat), deep blue diamond. It is legendary for the curse it supposedly puts on whoever possesses it. Previous owners include Kings Louis XV and XVI and Marie Antoinette.

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.
