From Galleries: "Diamond's Crystal System is isometric; 4/m bar 3 2/m. Crystal Habits include isometric forms such as cubes and octahedrons, twinning is also seen."
From Wikipedia:" Type IIa diamond can be colored pink, red, or brown due to structural anomalies arising through plastic deformation during crystal growth. These diamonds are rare (1.8% of gem diamonds), but constitute a large percentage of Australian production."
That depends, some gems are being made now to look almost completely like the real thing. However these are marked specifically because they are so hard to tell from natural diamonds. However, cheap diamonds that are crystal or glass will be obvious form the naked eye due to the clarity, and color.
Blue diamonds are blue due to the inclusion of very trace amounts of boron. Blue diamonds are white diamonds that happened to grow near a source of boron. The boron is included in the diamond crystal and substitutes in a few spots for carbon. Boron has three electrons: carbon has four. When combined, this creates an opening allowing some light energy to be absorbed. Incoming red light is thus filtered out returning a blue color to your eye. The Hope Diamond is the most famous of the blue diamonds. You can read the link, below, to learn more details of how boron makes diamonds (and LED's) blue.
yes diamonds are rare and beautiful
Diamonds are not necessarily disappearing. Diamonds are being mined all over the world, every day.
The structure of the carbon atoms make diamonds hard, the hardest natural mineral. Their crystal habit is octahedral and their crystal system is isometric-hexoctahedral.
A raw diamond has these geometric characteristics: its crystal habit is octahedral, and its crystal system is isometric-hexoctahedral (cubic).
Diamonds.
According to the Galleries site: " Diamond crystal system is isometric; 4/m bar 3 2/m and its crystal habits include isometric forms such as cubes and octahedrons, twinning is also seen."
Diamonds, emeralds, saphires, peridot, and topaz are some crystal gems.
Isometric
Diamonds are a natural occurring crystal form of carbon. They can be artificially made.
Carbon in a tight crystal lattice form can be found in all diamonds.
Crystal chandeliers, diamonds, etc.
Herkimer "diamonds" are twinned quartz crystals and so could be recognised by crystal shape alone. also, diamonds superior hardness would make it stand out from a Herkimer "diamond" if you were to test the two against a beryl or corundum crystal.
This will be a crystal dragon.
