Coal (graphite) is black and diamonds are clear because of the way carbon atoms are connected. In diamond each carbon atom is connected to the others forming points of a pyramid. In graphite (coal) the atoms are connected forming flat planes. These planes can absorb light of all wavelengths and hence are black. The pyramids in diamond, on the other hand cannot absorb any visible light and reflect all of it and thus are transparent.

Yes, if the cut of the two stones is the same. The whole purpose of the color alphabet is to identify the intensity of the color.AnswerNot necessarily - while a higher color is usually more expensive, if the lower color grade diamond is cut to much better standards, then it can be more expensive but of lesser color. Cut is very important as it controls the brilliance. When a diamond cutter has to cut a piece of rough, they have to balance the final carat weight with how beautiful they want to make it. Example, compare the cost of a regular round brilliant versus a hearts and arrows cut round brilliant. The hearts and arrows will be noticeably more brilliant, but also more expensive.
There are a few, but all are synthesized (lab grown) and not naturally occuring. The list would be: Rhenium Diboride(ReB2), Ultrahard fullerite (C60), and Aggregated diamond nanorods, or ADNR. All three are able to scratch diamond. The hardest of all known materials is aggregated diamond nano-rods, which are ultrahard fullerenes forced together, creating small diamond rods in a random arrangement (versus the orderly arrangement of diamond).
The input of a pencil sharpener is a pencil, which typically consists of wood, graphite, and sometimes a metal ferrule with an eraser. The output is a sharpened pencil, producing a fine point for writing or drawing, along with wood shavings and graphite dust as byproducts. Essentially, the sharpener removes a portion of the pencil's material to create a usable writing tip while generating waste in the process.
The word versus is a preposition; therefore, it doesn't have tense.
You don't need to defeat the Elite 4 20 times, your rival is at the Fight Area every Saturday.
To me 'Versus' means 'against' as in 'Portsmouth versus Manchester United'.
You can review the chart, below, to determine the specific gravity of diamond versus other gemstones, including several different types of rubies. From the chart you can deduce that depending on the type of ruby, it may or may not be exactly comparable to diamond.
The ISBN of Aliens versus Predator versus The Terminator is 1-56971-568-8.
What is the difference between the first and second phases of the prewriting process? O A. Outlining versus writing B. Brainstorming versus editing O C. Organizing versus writing D. Generating versus organizing
The diamond necklace plays a central symbolic role in the story. It represents appearance versus reality, as well as materialism and pride. The main character borrows the necklace to appear wealthy, but losing it leads to years of hardship. In the end, the revelation that the necklace was fake highlights the irony of her suffering and teaches a powerful lesson about vanity, honesty, and societal pressure.
