WHY NOT CHOOSE YOUR OWN DIAMOND? SPEAK TO US TODAY!
All diamonds are assessed and categorised by the 4 C's. Introduced by the GIA (Gemmological Institute of America) in the 1940's. These four criteria are used to determine a diamonds price - Colour, Clarity, Cut, and Carat Weight. We are happy to advise you on all diamond enquiries. Our Diamond Brokers supply us with 'Certified & Non Certified' diamonds at excellent prices. We guarantee to beat any quote you may have had on a 'Like for Like' basis.
REFERS TO THE WEIGHT OF A DIAMOND
Carat is often confused with size even though it is actually a measure of weight. One carat is equivalent to 200 milligrams. One carat can also be divided into 100 "points".
A 0.75 carat diamond is the same as 75-points or a 3/4 carat diamond.
Does a 1.00 carat diamond cost exactly twice the price of a half-carat diamond?
No! Since larger diamonds are found less frequently in nature, this places them at a rarer level. A 1.00 carat diamond will cost more than twice that of a 1/2-carat diamond, assuming colour, clarity and cut remain constant. Cut and mounting can make a diamond appear larger, or smaller than its actual weight. Stephen Jones Jewellers will take you step by step through the process of selecting the perfect mount to compliment your diamond. We also supply 'Certificated Diamonds'.

REFERS TO THE PRESENCE OF INCLUSIONS
Every diamond is unique. Nature ensures that each diamond is as individual as the person who wears it. Naturally occurring features, known as inclusions, provide a special fingerprint within each stone. Inclusions are natural identifying characteristics 'Birthmarks' from when the diamond was first formed in the earth. They may look like tiny crystals, clouds or feathers.
The position of inclusions can affect the value of a diamond. There are very few flawless diamonds found in nature, and therefore these diamonds are the most valuable. Inclusions are ranked on a scale of perfection, known as Clarity. Above we have shown a selection of five grades from the clarity scale. The clarity scale, ranging from F (Flawless) to I (Included) is based on the visibility of inclusions at a magnification of 10x. The greater a diamond’s clarity - the more brilliant, valuable, and sought after it is.
REFERS TO THE DEGREE OF WHICH THE DIAMOND IS COLOURLESS
Diamonds are found in almost every colour of the rainbow, but white-coloured diamonds remain most popular. Diamonds are graded on a colour scale which ranges from D (colourless) to Z.
Colour differences are very subtle and it can be difficult to determine the differences between two colour grades. Therefore, colours are graded under controlled lighting conditions and are compared to a master stone set for accuracy.
Truly colourless stones are graded D and are treasured for their rarity. However, colour preference ultimately depends on personal taste and budget. Ask us to explain to you about the colour grading system used for diamonds. Nature has also created diamonds with intense shades of blue, green, yellow, orange, pink or - rarest of all - red.
These natural coloured diamonds are known as 'Fancy Colours' and are extremely rare and highly priced!
REFERS TO THE PROPORTIONS, POLISH AND SYMMETRY
Nature determines so much about a diamond, but it takes a master diamond cutter to reveal the stone's true brilliance, fire and ultimate beauty.
Based on scientific mathematical formulas, a well-cut diamond will internally reflect light from one mirror-like facet to another and disperse and reflect the light back through the top of the stone. This results in a display of brilliance and fire. Diamonds that are cut too deep or too shallow lose or leak light through the side or bottom of the stone, resulting in less brilliance and are priced accordingly.
Cut is often confused with the shape of the diamond - round, square, pear, or heart, for example. A round diamond is symmetrical and capable of reflecting nearly all the light that enters it, but only if it is cut well. How well a particular diamond is cut will fall into one of these five categories - Excellent, Very Good, Good, Fair, and Poor.
