We are specialists in diamonds and precious stones, as the owner of Jyoti Jewellers has worked across the industry and has decades of experience, having begun as a diamond cutter and polisher before eventually owning his own business.
We offer industry standard certificates of authentication for your peace of mind.
Along with all jewellery we sell in store, we can also create bespoke jewellery items which would also come with certification.
We can also take a look at older jewellery that may not have a certificate, if you would like to confirm the authenticity of the stones.
For more on what to look out for when buying or selling diamonds, the 4Cs are listed below.
What are the 4Cs?
While we may think of the diamond’s cut as shape (round, princess, pear), it’s really about how well the diamond’s facets interact with light.
The quality of cut is crucial to a diamond’s final beauty and value and is the most complex and technically difficult to analyse out of all four grades.
Natural diamonds are created deep in the earth under incredible heat and pressure. Due to this process, the diamonds can have a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes’. This is how the clarity of a diamond is determined. The closer to perfection a diamond is, the higher its value.
Evaluating the colour of a diamond is determined by the absence of colour. A chemically pure and structurally perfect diamond has no hue and so, has a higher value.
The industry standard for grading colour begins with the letter D, representing colourless and continues on with increasing colour, to the letter Z.
Many of these colour distinctions are so subtle that they are invisible to the naked eye but they make a big difference in diamond quality and price.
A diamond’s carat weight is a measurement of how much it weighs. A metric carat is the equivalent of 200 milligrams and is a measurement used to weigh not just diamonds, but also other gemstones and pearls. A carat can be subdivided into 100 points.
With everything else being equal, the price of a diamond rises with carat weight, since larger diamonds are more rare and more desirable. However, two diamonds of equal weight can have different values and prices, because of the other three factors – cut, clarity and colour.
