Various Facts About Diamonds

Diamonds are naturally occurring on earth and they stand out as a unique material. Here are some facts about diamonds:

- diamonds are made of pure Carbon atoms

- diamonds are the hardest naturally occurring substance on the planet

- graphite is also made of pure Carbon and is the more stable form of that element

      - because of this, diamonds naturally degrade into graphite, though it would take millions of years to be noticeable

- diamond sizes are measured in carats

      - 1 carat is equal to 200 milligrams (or 0.00705 ounces)

      - larger carat diamonds are worth much more than smaller, so two 1-carat diamonds are worth much less than one 2-carat diamond

- diamonds must be cut in order to be pretty for jewelry

      - cutters must cut along the diamond's tetrahedral plain, where it is weakest

      - roughly 75% of a diamond's weight is lost in cleaving, sawing, cutting and polishing

      - so a 4-carat diamond in the ground may only be about 1 carat by the time it is in jewelry

- approximately one ton of earth must be moved for every one carat of diamond mined

- the word "diamond" comes from the ancient Greek word "adamas", which means invincible

- Diamonds are rated as a 10 on Mohs Hardness Scale used by mineralogists

      - 10 is the highest on the scale, while 1 is the lowest (Talc is rated as a 1)

      - Window glass is rated as 5.5, so harder minerals (like Emarald, Topz, and Tungsten) can also scratch glass

      - Because diamonds are rated as highest (10), so other naturally occurring substance can scratch diamonds

- Diamonds are rated as a 10 on Mohs Hardness Scale used by mineralogists
