Natural diamonds occur in many different colors, from pink and yellow, to brown, blue and even black. But that’s not what is meant by diamond color.

This year, the diamond industry is celebrating the 100th anniversary of the “Brilliant Cut Diamond”. The round brilliant, which remains the most popular, classic diamond cut until today, was developed by a young engineer and diamond cutter called Marcel Tolkowsky, when he was just 19 years old.
