The One

Few diamonds are good enough for Whitakers and only one in a hundred, can be The One. Whitakers The One is the diamond that takes five times longer to cut perfectly. The diamonds that qualify to be The One are cut from the purest hand selected rough diamond crystals to ensure their brilliance. What makes The One unlike any other diamond is the perfectly symmetrical ring of eight hearts on the bottom, accurately aligned with eight precision cut arrows on top to ensure maximum brightness and scintillation. As a result, The One diamond truly sparkles like no other.

GIA Certified

Whitakers Jewellers sells diamonds which have been certified by the Gemological Institute of America (GIA). GIA is the world's oldest, largest, and one of the most respected independent laboratories. Unlike some other labs, GIA is not owned or partially owned by diamond wholesalers or retailers, and is a non-profit organization. GIA actually developed the "4 C's" diamond grading system (used almost universally today) to provide truly objective standards in the evaluation of a diamond.


John Whitaker has developed a framework for recommending diamonds based on his extensive training at the GIA campus. Over time, John saw the need to develop W-Certified Diamonds, which are assessed based on the GIA standard quality controls, but also on how they look. W-Certified diamonds do not come with independent certification from a laboratory but are assessed and graded by John Whitaker. These stones are hand picked from large parcels of stones to provide excellent value for money along with high quality.


The single biggest cost factor when it comes to diamonds is size; as the carat weight increases, so does the price. A one carat stone will be two and a half times the price of a half carat stone with similar cut, clarity and colour grade.
We can adjust certain qualities of a stone in order to cater for other qualities which you or your partner may consider to be more important than the others. For example if the carat of the stone matters more to you than the quality of the diamond, but you're trying to keep to a budget, we can massage the , and to ensure your priorities are met.
It's important to try and find a balance in every stone and every piece we create. and explain to us what it is you're looking for in a diamond, so we can help you find it, set it - and see it sparkle


Did you know that when a diamond is lower in colour grade, the stone has an increasing degree of yellow or brown tinge?
It's actually a lack of colour that makes a stone more precious. Colour grades are not finite - it's more accurate to think of the grades like brackets. Graders use amaster stone which has been graded to the centre of colour, and compare and contrast every individual stone to see which window it fits into on the scale. Although the white diamond is the premium or clear diamond, it can depend on the as to how highly you may want prioritise a higher colour grade.
There's a widely held fashion tip - if you want to make your teeth look whiter, wear red lipstick. This theory works on the basis that a surrounding colour can highlight and hide different things - like the whiteness of your teeth. A slightly yellow tint to a stone which is to be set in white gold or platinum would be somewhat noticeable. It's for this reason Whitakers would recommend you select a colour grading of G or better.
But if your stone is to be set in yellow or rose gold, a stone with a lower colour grading could also be a good choice as the naked eye is unable to pick up the subtle differences between the yellow colour in the gold and the yellow tint in the diamond. Setting a H colour graded stone in yellow gold can actually make the diamond look much brighter.
The colour of a stone and how heavily this should be weighted in your decision really depends on the context of your chosen setting. At Whitakers, we believe you should invest in things you can see as opposed to things you can't. Come in store and speak to one of our friendly staff - they'd love to help you decide whether colour is a worthwhile investment for your selection.


Stones are graded depending on the visibility of the marks. Think of a diamond as a 3D prism. If you zoom in closely, in some stones you'll be able to see just a few tiny cracks inside the prism. Remembering that a diamond is like a little room of mirrors, cracks can change the way light bounces inside the prism and out to your eye. For lower graded stones, these natural growth marks can impact the passage of light.
Marks which can be seen with the naked eye are classed as either P1, P2 or P3. If marks can be seen easily with a microscope, they are graded as SI 1 or SI 2. If marks can be spotted after a few minutes using a microscope, the stone is graded as a VS1 or VS2 stone. If a jeweller has difficulty spotting marks in perfect lighting conditions under a microscope, the stone is classed as VVS or loupe clean.
Marks in the SI categories can't be seen by the naked eye - they require 10x magnification for even a skilled jeweller to identify. Whitakers recommends you look at W-Certified stones, which are graded between VS 2 to SI 2, for the best value for money.


Because we would rather you invest your money in things you can see than things you can't, we'll help you strike the right balance between all qualities of a stone, so the ring you choose is just right.
The cut of the diamond is the X-Factor, and makes all the difference between a big stone, an eye clean stone - and a stone which is truly stunning. There are five cut grades, ranging from Poor, Medium, Good, Very Good and Excellent.
Consider the role of cut in the same way you would with hair, or a suit. Hair can be richly coloured and healthy, but if someone has a terrible haircut, they just won't look good! Similarly, a suit made of beautiful material will look terrible if it isn't cut well. It's exactly the same with diamonds. You may have a beautiful large, clear, white diamond - but it won't look stunning unless the cut is just right. They say there's only two weeks between a good hair cut and a bad one, but diamonds are forever... so it's important to get this cut right!
A diamond is like a little room of mirrors and windows. A stone's brilliance is determined by how well the light is let in so it can best be reflected inside the prism and out to the eye. When the light bounces around inside the prism of the diamond and back out to your eye, it creates a unique sparkle. Having a well cut diamond ensures your room of mirrors is arranged in such a way that every surface will reflect light and direct it to create a sparkle. The better your room of mirrors is arranged, the more brilliance your stone will have.
