There has been a range of posts devoted to blues, but we tried to concentrate on certain diamonds gem and jewel, while a little was said about their origin. So, now let's have a closer look at blue diamonds, their origin, price,colors and mounting.
Historically, the majority of blue diamonds have been mined in India, however lately blue and grey-blue diamonds are found in Australian and South Africa. The Cullinan Diamond Mine in South Africa is the only significant mine in the world where blues are found in plenty. Well, the word 'plenty' correlating to diamond number does not necessarily stand for a large number, as only a couple of blue diamonds are qualified by GIA and can be used in fine jewelry.
Diamond is pure carbon, but there can be some 'impurities' that give color to a gem. In case of blue diamonds, this is boron that is responsible for blue shades: from light sky blue to deep greyish blue. There is a common mistake to think that all blue diamonds are like the famous Hope Diamond. The thing is that the majority of all blue diamonds are lighter than the Hope Diamond. To differentiate the colors there is a gradation scale for blues: fancy light, fancy, intense, deep, and vivid. Though a subtle difference between fancy and intense colors, but it has significant affect on a price! Say, one carat of light blue diamond may cost $30,000-70,000 while intense can go for $100,000-250,000 per carat. Collectors and most exclusive dealers should pay from $250,000 to $500,000 per carat of vivid blue diamond, mind that fact that large diamonds can cost much expensive.
Color and size are not the only factors that determine the high price, there is also a color combination that significantly skyrockets the price. There are blue diamonds that exhibit green color, the one resembling the Caribbean ocean waters. Of course, such greenish blues feature really high price tags, so that only a few true diamond lovers can afford to purchase them. Grey can also be a secondary color in blue diamonds. It gives unique steel blue color as well as affects the price.
What is more, there is a thing that significantly influences the perception of any blue diamond – it is the mounting. The latter can be compared to the a framed picture, where a frame makes the painting. The visual perception of the blue diamond is determined by the mounting it is set in, say the same blue diamond can have different play of color when it is mounted in a prong or bezel setting. Also, you can choose to contrast your blue diamond with other colored diamonds to emphasize its color value. Anyway, it is better to ask a competent jeweler for advice, so that he could offer you the best setting to bring out the unique color of your blue diamond.
