Below you will find explanations of them however to properly understand the differences please visit us so we can show you.

Cut
When we talk about a Diamonds cut we are not just referring to its Shape, But its proportions and finish. In our opinion it is a diamond most important characteristic.

The facets of a diamond should be aligned at precise angles in relation to each other to maximize the light reflected from the diamond. If these angles stray from this ideal the amount of light being reflected is diminished and therefore the diamonds has less brilliance and sparkle. When the maximum amount of light is reflected, a diamond sparkles with fire, brilliance and scintillation.

The cut of a diamonds is the only characteristic affected by Man, All other characteristics occurred naturally as the diamond was formed millions of years ago! Don’t worry we have done the hard work for you having already selected the best cut diamonds for our showroom. Our insistence of the best from our suppliers means our diamonds stand out. This is impossible to show online but a visit to our show room will show you all you need to know.

Colour
Diamonds vary enormously in colour with most of them carrying subtle tones of yellow, and brown. Very few are truly colourless, and these are the rarest and most highly valued. The colour scale starts at D (colourless) and ends at Z with diamond drawing slightly more yellow or brown as you go through the scale.

The differences can be subtle. An unskilled eye may struggle to differentiate between two adjacent grades of Colour. Over the years of buying diamonds we have learnt no to get to hung up on a particular colour our diamonds are selected for their individual beauty, a diamonds colour is assessed under laboratory lighting from the side of the diamond, while this process gives consistent results it does not mimic the way a diamond is seen in real life. 

Diamonds are usually seen from the top in everyday lighting conditions the face up Colour of a diamonds is affected but the cut of the stone and also other factors including fluorescence which can mean not all diamonds the same colour grade look the same! Confused? Visit us and see the diamonds with your own eyes it will make more sence. 

Clarity
It is rare to find a flawless diamond. Most diamonds contain tiny imperfections, called inclusions, which are created by nature and make every diamond unique. Inclusions can range from minute dark or light solid fragments, crystals, cleavages, fractures and feathers. Many inclusions are invisible to the naked eye and can only be assessed by a expert using magnification.

The more inclusions a stone contains and the easier they are to detect will determine the clarity grade. Diamonds which have inclusions visible to the naked eye are rated lowest on the clarity scale (I1, I2, and I3.) The diamonds you will find at Tustains will always be clean to the naked eye.

Carat
Diamond weight is stated in carats, a measurement derived from the more romantic original scale of comparison using the seeds of the carob tree which were very uniform and consistent in weight. Precision balances are now used and a carat has been standardized as equivalent to one fifth of a gram.

It is important to note that diamonds of the same weight don't necessarily have the same size appearance. Those cut too shallow or deep may look small for their weight, or suffer in brilliance.
When diamonds are mined, large gems are discovered much less frequently than small ones, which make large diamonds much more valuable.

Diamond prices rise exponentially with carat weight. So, a 2-carat diamond of a given quality is always worth more than two 1-carat diamonds of the same quality.
