Carbon is one of the most common elements in the world, and is one of the four essentials for the existence of life. Humans are more than 18-percent carbon. The air we breathe contains traces of carbon. When occurring in nature, carbon exists in three basic forms:

      • Diamond - an extremely hard, clear crystal
      • Graphite - A soft, black mineral made of pure carbon. The molecular structure is not as compact as diamond's, which makes it weaker than diamond.
      • Fullerite - A mineral made of perfectly spherical molecules consisting of exactly 60 carbon atoms. This allotrope was discovered in 1990.

Diamonds form about 100 miles (161 km) below the Earth's surface, in the molten rock of the Earth's mantle, which provides the right amounts of pressure and heat to transform carbon into a diamond. In order for a diamond to be created, carbon must be placed under at least 435,113 pounds per square inch (psi or 30 kilobars) of pressure at a temperature of at least 752 degrees Fahrenheit (400 Celsius). If conditions drop below either of these two points, graphite will be created. At depths of 93 miles (150 km) or more, pressure builds to about 725,189 psi (50 kilobars) and heat can exceed 2,192 F (1,200 C).

Most diamonds that we see today were formed millions (if not billions) of years ago. Powerful magma eruptions brought the diamonds to the surface, creating kimberlite pipes. Kimberlite pipes are created as magma flows through deep fractures in the Earth. The magma inside the kimberlite pipes acts like an elevator, pushing the diamonds and other rocks and minerals through the mantle and crust in just a few hours.

Diamonds are not exclusive to Earth. Scientists believe that diamonds may one day be found under the moons surface. Neptune and Uranus also contain a lot of the hydrocarbon gas - methane which could possibly turn to diamond at fairly shallow depths!

Diamond Carat, Cut, Clarity, Colour

A carat is a unit of measurement, it's the unit used to weigh a diamond. One carat is equal to 200 milligrams, or 0.2 grams. Their are 100 points in 1 carat, so a 1/4 of a carat would be 25 points. Please note: diamond carat is different to the meaning of karat which is used for determining the purity of gold.

The cut of a diamond determines its brilliance. Diamonds are cut to different heights, the best type of diamond to buy is one that is not too shallow or not to high but evening proportioned with plenty of cuts/facets in order to let as much light into the stone as possible.

Polish and symmetry are two important aspects of the cutting process. The polish grade describes the smoothness of the diamond's facets, and the symmetry grade refers to alignment of the facets. With poor polish, the surface of a facet can be dulled With poor symmetry, light can be misdirected as it enters and exits the diamond. The interrelations between the different areas of the diamond as listed below are all taken into account when creating the perfect diamond, Each part of the diamond has to be cut in such a way to reflect the light to its full potential.

You can have a big diamond of poor quality which will be cheaper than say a small good quality diamond. Poor quality is determined by the amount of inclusions within the stone, inclusions can be visible to the eye by identifying grey areas within a dull stone. For small stones you will need an eye loop which is used to magnify the facets.

Diameter:The width of the diamond as measured through the girdle.

Table:The largest facet of a gemstone.

Crown:The top portion of a diamond extending from the girdle to the table.

Girdle:The intersection of the crown and pavilion which defines the perimeter of the diamond.

Pavilion:The bottom portion of a diamond, extending from the girdle to the culet.

Culet:The facet at the tip of a gemstone. The preferred culet is not visible with the unaided eye (graded "none" or "small").

Depth:The height of a gemstone measured from the culet to the table.

The different cuts/shapes of diamond that are commonly used are: rectangle, square, round, pear shape, heart shape, marquise which is a tapered oval shape.
Diamonds come in hundreds of different colours and shades, white is the most commonly used but is not the cheapest as other colours such as black have been dyed to change the colour.

Cubic Zirconias

Cubic Zirconia is well known as a substitute for Diamonds, due to its high hardness and great fire. It is a man-made, synthetic jewellery gemstone. But in recent years, it has established itself as a gorgeous gem in its own right. Cubic Zirconia is a beautiful synthetic gemstone that is durable and inexpensive and now even comes in any colour of the rainbow, making it even more desirable.

CZ Compared to Diamonds

To the untrained eye, Cubic Zirconia looks identical to a good quality Diamond, but Zirconia has slightly less brilliance or sparkle than a Diamond and more fire or flashes of colour. The overall effect is so similar that it can even fool a trained gemmologist on occasion. One great difference between Cubic Zirconia and Diamond is weight. Cubic Zirconia is about 75% heavier than a Diamond. A piece of CZ the same size as a one carat Diamond weighs about 1.75 carats. Zirconia is also more brittle than natural Diamond and softer. Cubic Zirconia is also flawless, instead of natural diamonds which usually contain impurities and inclusions. But today Cubic Zirconia can be produced in nearly all colors, also Cubic Zirconia with inclusions are made in laboratories! Gemmologists agree that Cubic Zirconia is the finest Diamond alternative because it comes closer than any other gem material to matching the characteristics of a Diamond. Most people, even trained gemmologists, cannot tell the difference with the naked eye.

Fire and Brilliance

Cubic Zirconia or CZ for short has slightly less brilliance (sparkle) than natural diamonds, while having more fire (flashes of rainbow colours). The overall effect is so similar to diamond that trained gemologists often require special equipment to tell them apart.


There are only very few substances on earth harder than Cubic Zirconia. With a hardness rating of 8.5 on the Mohs' scale , CZ comes close to matching diamond's perfect 10. Yes, Cubic Zirconia will scratch glass, just like a natural Diamond.

Jewellery Design Tips

When designing a piece of jewellery for us to hand make for you it is best to consider the overall look and feel you want to achieve, whether it be chunky or delicate, intricate/fussy or simple in appearance. A good place to start is to think which type of occasion you want to wear the piece of jewellery for and what garments you want it to match with. Once you have decided on these points you can use a ruler to work out the thickness of metal and width or length of the design, once you have worked this out you can decide on the detail which will be suitable to fit within these measurements. Think about balancing the design with a focal point, maybe you could have a nice sparkly vibrant stone in the centre and include some kind of detail on either side of the stone.

It is a good idea to set yourself a budget and work your deign around it, for example if you would like to have your design made in gold but your budget is not enough for this it may be worth considering to have a design made from silver and to have gold highlights added to it which will give it an expense look but will still be within your budget.

Please contact Thomas Nayler if you wish to discuss your design ideas and he will be more than happy to advise you.

Why Buy Custom Handmade Jewellery?
