Diamond can be safely called the world's most popular gem. Most valued are diamonds, that is, cut diamonds. The stone is a mineral of the carbon group, undoubtedly the most beautiful among other minerals.
Instructions
Step 1
A transparent crystal with a bright play of light and a wide range of refraction is a diamond. The most common diamonds are white, they are virtually colorless and have a bright brilliance. The most expensive are black and pink diamonds. In general, the color gamut of these stones is very wide, therefore they are classified according to the predominant shade. Typical diamonds are stones in the spectrum from white to yellow, the rest are considered atypical, rare.
Step 2
Pure diamonds are expensive, most often there are stones with black inclusions in the composition, this is carbon. Jewelers have learned to get rid of "debris" by drilling it out with a laser, but the quality of the stone is reduced because of this, although the tunnels are not visible.
Step 3
We can say that a diamond is the only precious stone in every sense. If prices for other stones can change, then falling, then rising, the cost of diamonds is growing steadily. It's all about not only the beauty and unique properties, but also the rarity of this mineral. The price of a diamond in the entire modern history has decreased only once, when a large deposit was discovered in Brazil. However, over time, it depleted, and the value of diamonds began to rise again.
Step 4
The diamond is believed to have received its name from the Greek word Adamas, which means "indestructible." At first, mankind valued diamonds only for their physical properties, for their extreme hardness. In the rank of precious stones, diamond was lower than emerald and ruby until the Middle Ages.
Step 5
Diamonds can be precious and industrial; their main difference from precious stones is that they do not have unique beauty and aesthetic appeal. Such diamonds can be used in production. Approximately three quarters of the stones after extraction go not to jewelers, but to other industries.
Step 6
Stones with purity and transparency, without spots and flaws, are used only in jewelry. To turn a diamond into a diamond, only circles with diamond chips are used when cutting - nothing else can give the desired result.
Step 7
Interestingly, in its composition, diamond is almost identical to simple graphite, which we use, say, in pencils. And this graphite does not have such strength, the whole point is not in the composition, but in the crystalline structure.
