You are looking for a diamond with a good cause. You're a diamond lover. You've got countless pieces of jewelry studded with diamonds. You are looking to find an engagement ring with the right cause. You are one of those people who just can't resist the glitter and brilliance that goes with a diamond. Then you learn about the existence of blood diamonds. Your world is suddenly turned upside down.
Before diamond grading reports became so popular, there was a widespread preference in the trade for stones with fluorescence. These diamonds were called "blue-white" diamonds, and long time diamantaires can recall a time when many buyers would insist on diamonds with fluorescence. The preference began to decline after the FTC outlawed the misuse of the term "blue-white".
Harry Oppenheimer was the son of the founder of the company that would become the most successful cartel of the twentieth century - De Beers Consolidated Mines, Ltd. The South African company incorporated in 1888, during the burgeoning local diamond rush. At its formation and over the ensuing years, De Beers would successfully acquire countless interests in diamond mines and production facilities throughout the world. Diamond fluorescence indicates that the diamond emits light when exposed to Ultraviolet light (long-wave radiation) or sunlight. Diamonds exhibit fluorescence when small amounts of the element boron are present in the stone. Blue is the most common color of fluorescence, but other colors are also possible. The majority of diamonds don't exhibit fluorescence.
The impact of fluorescence has long been debated; in the Winter 1997 issue of GIA's Gems & Gemology, William E. Boyajian, President of the Gemological Institute of America, had the following to say on the topic: Opinions of even the most experienced trades people vary widely. With great conviction, some say that blue fluorescence of different strengths typically enhances a diamond's overall appearance. Others, as convincingly, say that it has a negative effect.
In addition to "Certificate of Origin", some countries have set up their own measures in order to ensure that blood diamonds are not released in their markets. Stricter measures and even stricter implementation is needed in order for this system to work efficiently.
