'Beautiful' is a judgement call. You are the judge.
Most man-made diamonds are coloured, because of the introduction of impurities into the process, and tend to be sized in the one to one-and-one-half carat size, because of the time it takes to 'grow' a diamond of this weight.
Both natural diamonds and lab-created diamonds are made from carbon, and in that sense are similar. A lab-created diamond has less monetary value than an equally graded natural diamond.
A certified gemologist will be able to determine the source of any diamond, to help you buy knowledgeably.
Because it is rare, beautiful, and timeless -- its natural assets are unmatched by any other gemstone.
A gold journal would be the best metal, since it does not oxidize (rust). A stone journal made of diamond would be the strongest, since it is the hardest natural stone.
diamond because it is beautiful and the hardest type of rock
No. Diamond is the hardest natural mineral on earth.
You might be asking whether or not you could damage a diamond using a hard stone. With that assumption, here is one answer. If you strike the diamond 'just right' and the diamond has an inclusion or flaw along a stress point that you happened to hit 'just right' with the large stone, you may be able to damage the diamond. Otherwise, a diamond is the hardest mineral known. And because of its value, you might not want to experiment with one using a large stone to damage it.
Yes, diamonds found in America are natural stones.
Yes, you can buy one, or inherit one. Note that a gemologist can confirm that the diamond is a natural yellow and not an enhanced stone.
"Beautiful" is relative. Some of the most valuable diamonds are large and show off the natural beauty of a cut and polished stone in the ways that it reflects and refracts light. You can explore a partial list of these stones, below.
The chemical boron is available with the carbon when the diamond forms, rendering the stone blue.
A diamond can be either, depending on the natural colour of the stone.
A cultured diamond is made in a laboratory and is not a natural stone, even though it is manufactured from carbon. Industrial diamonds have been made in laboratories in America since the 1950s, and gem-stone quality diamonds only recently. What can be inferred from the phrase in your question is a description of a gem-stone quality diamond (which is always less valuable than a natural diamond).
