Conflict diamonds, also called blood diamonds, are diamonds sold by rebel and terrorist groups to fund armed conflicts and rebellions against legitimate governments. By working only with reputable diamond companies Spheni Switzerland KlG does its best to avoid selling any diamonds from conflict areas such as Sierra Leone, Angola, Liberia, the Democratic Republic of Congo and the Ivory Coast.
Diamonds can come in wide spectrum of colours and are called fancy coloured diamonds when they are not considered as white. Red, green, purple and orange are one of the rarest colours, closely followed by pink and blue. Other colours such as yellow, brown, black and grey are enjoying increasing popularity thanks to their famous carriers. Carry Bradshaw received a black diamond ring from Mr. Big in the show “Sex and the City” and celebrities such as Adele and Jennifer Lopez have been seen with yellow diamond rings, to only name some examples.
Any other shape than a round brilliant is called a fancy shape diamond. They are a beautiful option to help you create a more unique design.
Fancy shape diamonds can be segmented into different types, from which many variations can be created:
Round-Edge Fancies: Oval, Pear, Marquise and Heart
Step Cut Fancies: Emerald cut, Asscher, Carre, Baguette and Trapezoid.
Modified Cut Fancies: Princess, Cushion and Radiant.
Depending on the shape, the light is reflected in a different way, changing the brilliance of your ring. In order to make the characteristics of a fancy shape have a positive impact into your ring’s look, it is very important to choose the right proportion of the gemstone.
Bellow you will see an example of two pear shaped gems with different proportions
Due to its proportions, the right one looks slightly more elongated than the left one:
There are many characteristics beyond the 4Cs that are almost blind to the naked eye, especially for untrained people. Diamond Fluorescence is one of those features that can change the price slightly without reducing the diamonds overall quality. The effect of fluorescence depends on the colour grade in combination with the fluorescence grade (none, faint, medium, strong, very strong) of the diamond. Fluorescence can have a positive impact on some type of diamonds or a negative one that could affect its clarity and even make it look milky or cloudy. In order to combine the characteristics perfectly, it is very important to work with an advisor you trust.
The four C’s are the most common characteristics to describe a diamonds quality, namely Carat (weight), Color, Cut and Clarity. There are many other factors that can influence a diamond’s quality and its value and depending on the certificate laboratory, the characteristics might differ from one lab to the another.
