Made upon carbon, the diamond is the purest of all precious stones.
Its unparalleled strength makes it lasts forever,
perhaps that is why it has been adopted as symbol of love.
A diamond has the capability to refract more light than any other gemstone. One which is free of interior inclusions or exterior flaws has nothing to interfere with the passage of light through the stone and so is considered to be of the highest quality. Such stones are very rare and correspondingly expensive! Most diamonds contain tiny natural marks called inclusions. The number of inclusions, their size and location all affect the diamond’s clarity grade. While it is true that the clearer a diamond, the better, minor inclusions will not compromise a stone’s beauty or endanger its durability.A Hartmann diamond is guaranteed to be from the premium end of these grades. We offer a range of diamond clarity grades from Flawless to SI2.
It is the cut that allows a diamond to make the best use of light. When a diamond is cut to the right proportions, light is refracted internally from one facet to another before being dispersed through the top of the stone. If the cut is too deep, some light will escape through the opposite side of the pavilion; too shallow and light will escape through the pavilion before it can be refracted. A master cutter ensures full light dispersion, maximising the inherent beauty of the stone. A master cutter ensures full light dispersion, maximising the inherent beauty of the stone.
The size of a diamond is measured in carat-weight. One carat is divided into 100 ‘points’, so that a diamond of 75 points, weighs 0.75 of a carat. While carat-weight is the most obvious factor when assessing the value of a diamond, two diamonds of equal size can have very different values, depending on their respective cut, clarity or colour. Bigger isn't necessarily better - diamonds of high quality can be found in all size ranges. However, one diamond of one carat is normally worth more than two diamonds of 0.50ct. each.
