This page, ironically, is coal; you WILL help by expanding it.
A gem (also called a gemstone, gemmie, 'emmie, fine gem, jewel, precious stone, or (((semi-precious stone))) is a piece of mineral which is made in a cut and polished form, it is used to make jewelry and other adornments, it also has other uses since its hardness has given it many uses. However, certain rocks (such as lapis lazuli and opal) and occasionally organic materials that are not minerals are also used for jewelry and are therefore often considered to be gems as well. Most gems have low malleability and high brittleness, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. It's artificial rarity is another aspect that lends much value to a gems and gives the ownership of gems status.
The link between gem and coal is not random as some people may think, gems are most of the time shown with a human made picture of a big shiny blue diamond. Diamonds are made of carbon and are created by extreme heat, pressure during long periods time. The fact that coal too is mostly made of carbon imply that even coal can become gem under specific condition, hard work and long time, and lets not forget that gems true quality and beauty is shown only after they are CUT and POLISHED. So your polishin can make it happen.
