We thought you might be interested in some of the following facts about diamonds.

1.It takes approximately 250 tonnes of earth to obtain a 1 carat diamond!

2.Only 1 diamond in a million is a weighs a carat or more.

3. 85 per cent of diamonds mined are not suitable to be used in Jewellery

4.Only a diamond can scratch or polish another diamond

5.Most diamonds are over three billion years old-some of the youngsters are 100 million years old!

6 Most diamonds are formed more than 100 miles beneath the earth’s surface.

7.At one time diamond colours were refered to only as A and B.As cutting equipment got better and it became easier to grade diamonds the range was expanded.In order to avoid any confusion with the old scale colours were started with D being the best are running all the way to Z.

 

We hope you enjoy some of these facts

 

 

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 Fluorescence refers to the diamonds tendency to emit a soft coloured glow when subjected to ultraviolet light.

Before we get into the details our overall opinion. Fluorescence should not influence your decision to purchase a diamond. Diamond Fluorescence is a hotly debated topic in the diamond industry, but a 1997 study by the GIA suggests fluorescence makes very little difference to the appearance of the diamond.

In the diamond industry, the existence of fluorescence in a diamond (caused by the natural mineral properties of the diamond), has caused many debates and has, in many instances, influenced the pricing of diamonds.

It is common to find that diamonds with colourless grades (D-E-F) or near colourless grades (G-H-I-J) are lower in price when they exhibit fluorescence.
A GIA study selected a group of similarly graded diamonds with varying degrees of fluorescence to be observed and commented on by study participants. Participants in the study included: trained diamond graders, trade professionals (e.g., jewellers), and average observers (general jewellery buying public).

Here’s a quote from the study:
“For the average observer, meant to represent the jewellery buying public, no systematic effects of fluorescence were detected. Even the experienced observers did not consistently agree on the effects of fluorescence from one stone to the next.

“In general, the results revealed that strongly blue fluorescent diamonds were perceived to have a better colour appearance when viewed table-up [ed: right-side up, as when placed in a setting] with no discernible trend table-down [ed: upside-down]. Most observers saw no relationship between fluorescence and transparency.”
In other words, for the average observer fluorescence made no difference and experienced observers (diamond graders and trade professional) did not agree on the influence of fluorescence. And contrary to previous theories, the experienced/trained observers most consistently determined that diamonds with strong fluorescence were the ones with the best color.

Bottom Line on Fluorescence
Don’t let flourescence unduly influence your choice when selecting a diamond.

If industry experts can’t agree on the influence of flourescence and constantly split hairs over its effect, we feel it falls into the range of minutiae that simply serves to confound and confuse, rather than inform the diamond buying public.

However, because of industry debate and prejudice (which appears unfounded), you may find colourless or near-colourless diamonds that exhibit fluorescence have slightly lower prices than those that do not. Our opinion? Enjoy the better value!!
