The Four C’s of Buying a Voltaire Diamond
Voltaire Diamonds has extensive experience sourcing gems that offer beauty, brilliance and excellent value. Every Voltaire Diamond comes with a certificate, this documents the characteristics of the diamonds quality, colour, cut, clarity and carat weight which are verified by an independent company with no conflict of interest between buyer and seller. Voltaire Diamonds only use diamond grading laboratories that have the strictest grading standards.
We strive for maximum brilliance and beauty in every Voltaire Diamond. The cut, or make of your diamond determines the level of sparkle, brilliance and fire visible in your gem.
To reflect and refract light most effectively, Voltaire diamonds must be cut to the correct proportions and polished so that each facet is precisely placed. Diamonds which are not cut and polished to these standards do not handle light correctly, diminishing both their beauty and value.
At Voltaire we insist on excellent quality of cut so our diamonds truly sparkle.
Diamond quality and value is also determined by subtle colour differences, sometimes barely discernible to the untrained eye. The best and rarest diamonds appear colourless ( white) or near colourless and are graded D to I with D and E being extremely rare. Colour quality below I then diminishes as yellow/brown tones become more evident. At Voltaire we specialise in white diamonds with colours in the range D – I.
A diamond’s clarity rating is a key measure of its overall quality. Almost every gemstone is marked with natures fingerprints called “inclusions”. The clarity grading of a diamond measures the position, volume and colour of its inclusions, which can be black or white in colour. The beauty and value of a gemstone is affected by obvious inclusions, as they affect the passage of light through the stone.
Some diamonds have no inclusions and are very rare, these are referred to as Internally Flawless. However, most diamonds have inclusions, some that are so microscopic that they can only be seen under 50 X magnification and others that can be seen by the naked eye.
The term carat refers to a measurement of weight as opposed to size. A carat is equivalent to 0.2 grams and is the unit of weight for diamonds. Carat is the most price sensitive part of a diamond as it refers to the mass and proportionate size. Diamonds are rare and as the size and carat weight increase they become very scarce.
At Voltaire, we supply all carat weights enabling you to buy the best quality and size for your taste and budget.
We only select diamonds that have no inclusions or ones that have inclusions so minute they are barely discernible, even under magnification.
