Diamond forms under high temperature and pressure conditions that exist only about 100 miles beneath the earth’s surface. Diamond’s carbon atoms are bonded in essentially the same way in all directions. Another mineral, graphite, also contains only carbon, but its formation process and crystal structure are very different. Graphite is so soft that you can write with it, while diamond is so hard that you can only scratch it with another diamond.
HOW TO PURCHASE A DIAMOND ENGAGEMENT RING
It should be one of the most memorable moments in your life. You pull an engagement ring out of your pocket and ask the love of your life to be your wife. You desperately want her to say yes and fall in love with her ring too, right?
You can make sure that happens if you follow these tips to pick out the perfect engagement ring:
Clarity grades assess the number, size, relief, and position of inclusions and blemishes.
The less color, the higher the grade. Even the slightest hint can make a dramatic difference in value.
Cut (proportions, symmetry, and polish) is a measure of how a diamond’s facets interact with light.
Rarity means larger diamonds of the same quality are worth more per carat.
