Blue Diamond
Blue Diamond (pronounced: /bluː ˈdaɪ(ə)mənd/) is a type of diamond that contains trace amounts of boron that give the gemstone its blue color.
Etymology
The term "Blue Diamond" is derived from the Old French word diamant, which is in turn derived from the Greek word adámas, meaning 'unbreakable', 'proper', or 'unalterable'. The prefix "blue" refers to the color of the diamond, which is caused by the presence of boron impurities.

The most famous blue diamond is the Hope Diamond, which is a deep-blue diamond and weighs an impressive 45.52 carats.
