Blue diamond gemstones loose are perhaps the best way of buying blue diamonds. You can find out quite easily if the diamonds are genuine by getting the diamonds checked. If diamonds are set into rings and other jewelery then it is very difficult to get a proper assessment of the true value of the diamond.
When buying blue diamond gemstones always ensure you get a independent gemological laboratory appraisal. This ensures that you know the value of the diamonds and can get adequate insurance also.
Diamonds can occur in nearly any color, though yellow and brown are by far the most common. Colored diamonds contain impurities or structural defects that cause the coloration, while pure or nearly pure diamonds are transparent and colorless. Colored diamonds tend to cost a lot more than the colorless. For example a one carat pink fancy diamond can sell for up to five times the price of a colorless diamond of the same quality.
Fancy diamonds are usually graded with the diamond in the face up position. This due to the fact that their cut can influence the apparent color and also because their price is based upon the face up color of the diamond. The more intense the color the higher the price.
Some diamonds are colored artificially using irradiation or a high pressure treatment. These are not worth as much as the natural colored diamond of course. The GIA does not consider treated diamonds as fancy diamonds.
Some points to keep in mind.
Always judge a diamond against a non reflective white background. A folded business card is good with the diamond placed in the fold.
If possible use comparison diamonds to determine the color grade. One cannot really rely on memory and professional grades don’t so neither should you.
Ensure you get a proper grading from a laboratory such as the GIA for example (more lab contacts are available from the laboratory list link on the left.
Keeping in mind the above it is possible to find and enjoy blue diamond gemstones loose to have set into your favorite jewelry.
