3-Rubies, sapphires and emeralds are all more rare than diamonds.

4-Not all diamonds are transparent. They come in a variety of colors (called "fancies"), including yellow, green, blue, orange, brown ("champagne"), purple, grey, black (called carbanado, recently shown to be meteroic), milky white, pink, and red. Red is by far the rarest.

5-Antacids taste like chalk because they ARE chalk, a.k.a. calcium carbonate.


Hope this helps, Give a thanks ! Haha
