What is an ‘eye clean’ diamond?
Being ‘eye clean’ affects the clarity and quality of a diamond, which will alter the price of any stone. If a diamond is ‘eye clean’ it does not visually show any inclusions or blemishes on the surface or interior when viewed with the naked eye. The diamond may feature an impurity, but it may only be visible with the use of a microscope.
The clarity of a diamond is one of the 4 Cs – Cut, Clarity, Colour and Carat - because it is one of the fundamental attributes to knowing how to judge a diamond. Clarity becomes especially important if impurities are noticeable to the naked eye in diamond jewellery or engagement rings.
Clarity refers to the level of inclusions such as scratches, blemishes, pockets of air and non-diamond material inside or on the surface of a diamond. Fewer or less obvious inclusions make diamonds rarer and more highly valued.
What imperfections can a diamond have?
Any rough diamond can suffer from interior or surface imperfections, known as inclusions or blemishes. Inclusions may be crystals of a foreign material or another diamond crystal, or the presence of structural imperfections such as tiny cracks that appear cloudy or white. Cracks are often known as fracture lines, needles or feathers depending on the mark they leave or their cause. Internal crystals or marks can appear as singular ‘pinpoints’ or as clusters known as ‘clouds’.
Famous Pink Diamonds of the World
Both scarce and popular, pink diamonds are extremely sought after and expensive. With the exception of a couple found in India, almost all of the world’s pink diamonds are now produced from one mine in Western Australia: the renowned Argyle Mine. This extreme rarity means that the gems discovered there are considered highly valuable. Have a look at some of the world’s most fascinating, expensive and large pink coloured diamonds!
The Star of the South

This beautiful diamond was cut into a cushion shape and is also known as Estrela do Sul, since it was found by a slave girl in a mine of the same name in Brazil in 1853. It weighs an impressive 128.48 carats (25.70 g) and is graded as a type IIa diamond, with a clarity of VS2 and a colour grading of light pinkish-brown. There is a white reflection of light from the diamond, whereas the refracted light has a definite rose tint which gives the stone a light pink and brown shade.

The Sancy Diamond

The most famous yellow diamond is the Sancy; an impressive 55 carat, light yellow diamond what fluoresces yellow and pink. However, it is the story of the diamond that makes it famous. It is thought that the Sancy originally came from India and legend has it that in 1477 the diamond was lost by Charles, Duke of Burgundy during a battle. Its first verified owner became Nicholas Harlai of Sancy, a French Ambassador, who bought the diamond in the late 1500's in Constantinople – hence the derivation of this stone’s name.

The Regent Diamond

This diamond was also commonly known as the Pitt Diamond and was discovered by a slave in the legendary Golconda mine, India, in 1698. The sparkler wasn’t hard to miss; it weighed an impressive 410 carats. However, the slave hid the stone and managed to escape to the coast – only to be murdered for the stone by an English sea captain.
The captain sold the stone to an Indian diamond merchant for an estimated £3,431. Thomas Pitt, Governor of Fort George in Madras, then bought the blue stone from the merchant in 1702 for £68,610. Thomas Pitt was grandfather to the famous American Revolutionist William Pitt and he was the one who transported the diamond to England for cutting.
The Regent Diamond is a cushion-shaped, brilliant cut diamond, white in colour but with a faint blue tinge. It now weighs approximately 140.50 carats and measures around 32mm x 34mm x 25mm. The moulding of the stone took 2 years before it was turned into the charming Regent Diamond – thought to be one of the finest cut diamonds in existence!

Diamonds: why it’s a good time to invest
This week the global gem-mining giant De Beers Group revealed that the world’s diamond supplies are running out. Despite recent economic hardships, the choice to invest in diamonds now may be a wise one.
According to the mining company, diamond mines are getting scarce and will eventually become history. De Beers has decided to reduce its production in order to extend the life of the mines.
The depletion in diamond mines will have a direct impact on the prices of stones. Diamond analyst at Royal Bank of Canada Capital Markets, Des Kilalea, explained that owing to the moderated output, diamond prices could rise by at least 5 percent every year for the next five years.
De Beers is responsible for 40 percent of global diamond sales, but this figure is now likely to decline. The company had an astonishing record of producing 48 million carats per annum, but will now reduce their diamond production to 40 million in 2011.
Are you an aspiring jewellery designer? Part Two
At Seventy Seven Diamonds we love to encourage talent and support up and coming designers in their struggle to become more skilled, successful and recognised. This is the second part of the blog series in which we identify some of the key challenges faced by jewellery designers and offer advice and information on current opportunities which they, as aspiring artistes, can use to their advantage for both creating and selling their pieces.
What can you expect?
In part one we outlined the job requirements for designers in general terms. If you’re fairly new to the game, here’s some more information about what you can expect to be involved in the job...
Jewellery designers plan the style and pattern of jewellery, silverware and other decorative metalwork products. As a jewellery designer, you could produce designs for mass production, or to be made individually or in small numbers by yourself or other craft-workers. For example, you could be commissioned to:
- Produce designs to meet the requirements of a client (known as a 'brief' or commission) or for general sale. This can include the work of large-scale designer line sales.
- Produce designs which are then made by other staff (if you work for a company).
