Diamonds
With a white lustre that never diminishes, platinum enhances a diamond’s sparkle. Platinum’s superior durability means that it is the most secure setting for precious stones.
The quality of diamonds is determined by the "4 Cs":
CUT: refers to the angles and proportions of the diamond. These determine its fire and sparkle. Cut also refers to the shape of the stone – round, square, pear or heart, for example.
COLOUR: defines the degree to which a diamond is colourless. The more colourless the diamond, the more valuable it is.
CLARITY: is determined by the number of inclusions (small markings found inside the diamond). The fewer the inclusions, the more valuable and rare the diamond is.
CARAT: describes the weight of the diamond, which is also related to its size. Smaller diamonds can be more expensive than larger ones depending on the quality of their cut, colour and clarity.
Cut
There are seven basic types of cut for diamonds and coloured gemstones. The most popular design features a center stone surrounded by diamonds or other precious gems. All the stones below can also be used as side stones, as well as baguettes and trilliants.
