Where Does The Sparkle Come From?

Friday, July 9th, 2010

The UK is not exactly known as the epicentre of diamond-mine country. So where do the diamonds for our fabulous ROX jewellery come from and how are they mined? The short answer is far away and ethically.

Pure carbon + colossal pressure + millions of years = rough diamonds (which can lose 50% of their weight once cut) for export. Sounds simple doesn’t it? In reality this equation is exceptionally rare. Once a potential site is identified there are three factors to consider when judging the merits of moving forward – how stable is the land around the site? How environmentally damaging would it be to mine the area? And finally, what type of terrain must actually be mined?

South Africa is, to this day, the largest exporter of diamonds in the world. Prolific diamond mining nations are Angola, Australia, Borneo, Botswana, Canada, Congo, India (where diamonds have been mined for over 2,800 years), Lesotho, Namibia, Russia, Siberia, Sierra Leone, Tanzania and Zimbabwe.

An industry concern amongst diamond jewellery producers is the ever-present issue of conflict diamonds. Here at ROX we’ve included a special webpage to help explain a) the nature and origins of conflict diamonds, and b) a written promise to you that all our diamonds are sourced ethically. You can also be sure that diamonds from our partners like Pandora jewellery, Links jewellery and Stephen Webster jewellery carry the same promise.

Safe And Sparkling

Monday, July 5th, 2010

Whether you’ve spent a lifetime building your jewellery collection or are just beginning to gather a few key pieces, making sure your treasure is safe and insured should be a key concern.

Simply relying on your homeowner or renter insurance may not be enough to sufficiently cover more valuable pieces adequately. Check your policy thoroughly to clarify the exact parameters of what your current policy will cover.

Taking out a specific insurance policy for your collection need not be complicated. The three most common types of policy are Valued At, Actual Value and Market Value Replacement.

Valued At policies are less common due to their expense. Say your diamond necklace is worth £1000 but of great sentimental value, the insurer will accept your own valuation, for example £1500, to cover the added cost of emotional upset. You can see why these policies are expensive!

Market Value Replacement policies are essentially the same as Actual Value, though, as the name suggests, your lovely diamond earrings would be replaced with a pair at the current market value rather than compensating you in cash.

Here are some key points to check:

* What are the terms with regard to storage of your pieces?

* Are basic repairs covered by the policy?

* Is your jewellery covered in transit and abroad?

Diamonds And Colour

Tuesday, June 29th, 2010

Although most diamonds appear to be colourless (or white), they may actually have subtle yellow or brown tones that can only be seen when they are compared side by side to other diamonds. These variations in colour are caused by traces of other elements entering into the diamond’s atomic make up as they are formed in the intense conditions of the Earth’s crust. Colourless diamonds allow more light to pass through them and so emit a more radiant sparkle than coloured diamonds. This is what makes “sparklers” so valuable as jewellery.

9ct white gold diamond cluster earrings 0.36ctTo grade ‘whiteness’ (or colourlessness), a jewellery colour scale is used that starts at D (colourless) and continues down through the alphabet to stones with traces of light yellow or brown colouring. The first three grades of D, E and F are often called the collection colour and are of course the most valuable. Truly colourless diamonds are an absolute treat for the eyes and make the most beautiful diamond jewellery imaginable. Diamonds graded from G to I are graded as slightly less than colourless but will appear virtually colourless to anyone with an untrained eye.

Normally, colour being present in a diamond makes it less valuable, but some diamonds come out of the ground in incredibly vivid colours. The diamond industry’s term for these diamonds are “fancy” colours and they can be any colour from pink to green or even bright yellow. These diamonds are incredibly rare and valuable, and are a true prize of diamond jewellery.

Diamonds – The Four Cs

Thursday, June 24th, 2010

Diamonds are assessed and graded by experts within the diamond industry according to the “four Cs”: cut, clarity, colour and carat (weight). If you may soon be visiting a jewellery store to shop for diamond rings, it can be helpful to know a little about these criteria.

Cut

Contrary to popular belief, the ‘cut’ of a diamond refers to its reflective qualities rather than its shape. The brilliance of a diamond depends heavily on its cut, so the angles and finish of any diamond are the key factors in its ability to negotiate light. A good cut gives a diamond that magical brightness that seems to emanate from deep inside itself.

Most diamonds contain some minor imperfections that have occurred during their formation. Industry experts call these imperfections ‘inclusions’.  The number, size and visibility of these inclusions are what determine the overall clarity of a diamond. Diamonds rings which are free of inclusions are fantastically brilliant and so are very highly sought after.

Colour

A colourless diamond allows more light to pass through it than a coloured diamond and so creates a greater sparkle. Completely colourless diamonds are rare so the more “white” a diamond’s colour is, the greater its value.

Carat Weight

A carat is the unit of weight by which diamond jewellery is measured, with one carat being equal to 0.2 grams (200 milligrams). Larger diamonds have a greater value per carat as they are discovered much less frequently than smaller diamonds.

Diamond Clarity

Thursday, June 17th, 2010

All diamonds are unique, and most have tiny flaws or imperfections which are known in the jewellery trade as blemishes or ‘inclusions’. These imperfections can be cavities, scratches or even delicate crystals that have been created within the diamond as it was forming in the earth. The term used to describe the presence of inclusions in diamonds is clarity.

18ct yellow/Platinum brilliant diamond ring 0.28ctA diamond that has fewer inclusions has a higher clarity, and is therefore of more value. The internal characteristics that are present in diamond jewellery can only be seen by looking through a special jeweller’s magnifying glass, known as a loupe. With a loupe, diamond jewellery can be divided into six main categories:

FL
Diamonds with no inclusions are referred to as ‘Flawless’ and are incredibly rare. Brilliant, flawless diamonds are the most beautiful jewellery of all.

IF
IF means that the diamond is Internally Flawless and that no flaws are visible under magnification, only small blemishes on the diamond’s surface.

VVS
The VVS grade means that the diamond is ‘Very, Very Slightly Included’.

VS
VS stands for ‘Very Slightly Included’ and means that minor imperfections are visible under magnification.

SI
SI means that the diamond is ‘Slightly Included’ and imperfections are visible under magnification and possibly with the naked eye.

I
I stands for ‘Included’ and means that imperfections are visible with the naked eye.

Numbers are used after some categories to grade the diamonds further. For example, a VS2 will have more or larger inclusions than a VS1.

At ROX, all of our diamonds are carefully selected for their quality. Available loose or in settings for rings, diamond bracelets, necklaces or earrings, we supply a wide range of diamond jewellery.

What Are Blood Diamonds?

Thursday, June 3rd, 2010

For most of us, the first time we heard the term Blood Diamonds was when the Leonardo Di Caprio film of the same name appeared in cinemas. So what are blood diamonds, and should you take steps to avoid inadvertently buying Jewellery which contains them?

Essentially, they are the stones which appear in Diamond Jewellery which have been sold in Africa in order to fund illegal operations of rebels and other terrorist groups. Countries that have been most affected by this are Sierra Leone, Angola, Liberia and the Democratic Republic of Congo, where many people have died in conflicts which have been funded by the sale of these stones which later turn up in everything from Diamond Bracelets to Eternity Rings.

9ct white gold brilliant diamond bracelet 0.50ctsThere have been moves to ensure that our Diamond Jewellery is free from these blood diamonds. Ten years ago, South African countries with a legitimate diamond trade began a campaign to track the origins of all rough diamonds, attempting to put a stop to blood diamond sales from known conflict areas. Their efforts eventually resulted in The Kimberley Process Certification Scheme (KPCS), an international effort to rid the world of conflict diamonds, and so far appears to be seeing success.

When you are buying diamond jewellery, don’t be afraid to questions when you are choosing diamond rings or diamond earrings. Ask the dealer where the diamonds you are looking at came from, what the company’s policy on blood diamonds is, and if the company can verify the origins of the stones.

Look After Your Diamond Jewellery

Tuesday, June 1st, 2010

You could be forgiven for thinking that you don’t have to worry about diamond rings becoming worn, but this is not entirely the case. Despite diamond jewellery being made from one of the hardest substances on earth, it can become worn, so make sure you follow a few guidelines and you will avoid this. For example, if you wear any other rings next to a diamond ring some abrasion may occur, as a diamond in direct contact with other diamond jewellery will rub away at the other stone. Eventually, your diamond may also be slightly worn down if they have been placed together for too long. Wearing two rings close together can cause the abrasion of metal as well, so it’s probably best if you never take your rings off to wear them on opposite hands or a few fingers apart.

There are a number of materials that can be used to clean diamonds and their mount, including soapy water, some detergents and alcohol, but don’t use abrasive substances which may damage your diamond jewellery. diamond rings can also attract grease, and after a while if not cleaned they will lose their sparkly and can become dull. This applies to all diamond jewellery, whether it is eternity rings, cluster rings or diamond bracelets, so a little bit of maintenance will ensure that your diamond jewellery will never lose its sparkle.

Ethically Sourced Diamonds

Thursday, May 27th, 2010

Because diamonds are small enough to be extremely easy to transport but very valuable indeed, the diamond market is an ideal target for illegal smuggling operations. Coupled with the fact that most of the stones of sufficient quality to be used in fine diamond jewellery and watches are found in some of the poorest and most troubled places on Earth, there is a recipe for trouble.

In these days of heightened consumer responsibility, the way diamonds can be used by violent and vicious regimes to gain power and the money to buy arms has been brought out into the light. In the past these ‘conflict diamonds’ found their way into designer watches and diamond earrings all over the world. Even some unlucky people’s wedding rings, bought in complete ignorance of the deadly serious issue of conflict diamonds, have been tainted by it.

9ct white gold diamond trilogy earrings 0.25ctHowever, times change, and in this matter they’ve changed for the better. All diamonds coming into the EU now have to be certified to come from conflict-free, legitimate sources. No conflict diamond may now be knowingly sold here, either as part of any diamond jewellery or as a cut stone.

You can buy diamonds from ROX with the full assurance that they are conflict-free. We’re proud to be a part of the new, more socially responsible trade in precious stones. So much so that we even scrutinise all our gold suppliers to make sure their practices are safe for workers and environmentally sound. We make sure that our jewellery is ethical jewellery.

What Is A Carat?

Tuesday, May 25th, 2010

The weight (and therefore the size) of stones used in diamond jewellery is measured in carats. They are a very old measure, and these days carat weights are the standard for precious stones. For precious metals like gold, carat is a purity measure rather than an outright weight, so that is slightly different. In diamond rings, the carat value stated may be the weight of the centrepiece stone or the combined weight of all stones including small chips- fell free to ask if in any doubt about any of our diamond jewellery.

Back in the early days of diamond trading for jewellery, the stones were measured against the weight of carob seeds, which are remarkably uniform in size and weight. One carob seed came to be one carat. There is a finer measurement called ‘point’. One point is one hundredth of a carat, so a half carat diamond is a fifty point diamond.

9ct white gold pave diamond heart ring 0.18ctsWhile size certainly does matter, diamond quality is also important. Clarity and colour will also affect the price and desirability of a given stone. So will the type of cut.

One carat is 0.2g. That doesn’t sound like much, but one carat diamond engagement rings are actually quite good and the central stone in question will probably look quite impressive. Most of the stones used in diamond jewellery are smaller than that. A 2 carat diamond is on the decidedly large side, and a 3 carat diamond is truly outstanding in size. Good quality loose stones of that weight are usually sold for tens of thousands of pounds when cut, or more.
