The stones in the jewelry store, the stories behind them are better than you think. Today, eight colds, each of them refreshs your understanding of the jewels。
It's a new time frame. It's a big reward. Pass
Cold knowledge 1: diamonds and pencil cores are the same element - carbon
Diamonds are one of the most hard natural substances in the world (most 10 degrees hard) and pencil cores are one of the softest things - they consist of exactly the same elements: carbon (c). The difference is only in the manner in which the carbon atoms are organized: diamonds form the four-faced structure (the diamond structure) of each carbon atom and the four carbon atoms around them, and the pencil core is the layer in which the carbon atoms are organized (the graphite structure). The heat pressure deep in the crust turns carbon atoms into diamonds, and the low temperature pressure on the surface makes it loosely organized into graphite. It's carbon, too, with different fates。
Cold knowledge 2: rubies and sapphires are the same minerals
Rubies and sapphires sound like two completely different gems, but their "mothers" are exactly the same — they're all gooks. Gwangyu itself is non-colored, but red when it contains trace chromium elements — rubies; blue when it contains iron and titanium — sapples. The other colours are called "colour sapphire". So strictly speaking, rubies are "red sapphires". In mineral science, only the red jade is named ruby, and all other colours are called sapphire。

Cold knowledge 3: pearls are afraid of water - though it grows in water
The pearls are from water, but the pearls themselves fear water. The main components of pearls are calcium carbonate (over 90 per cent) and organic shell angular protein (around 4 per cent). Calcium carbonate encounters water (especially chlorine in piped water) with slow reactions that damage the light of pearl layers. Even more serious is the fact that if the water penetrates a small hole inside the pearl (the perforated pearl), the remaining water causes organic decay and the pearls are yellow and degenerated from within. The pearls are properly maintained by taking them off in the shower, swimming them off, drying them with a soft cloth after sweating, and storing them in isolation from other jewellery。
Cold knowledge 4: europo contains up to 20% of water - water loss breaks
Opal is the most "waterful" jewel - can contain as much as 10-20%. Opor's charming colours (coloring effects) are derived from the distillation of light from numerous tiny silicones inside it, which are filled with water. When europo loses moisture (long-term dry environment or high temperature), the ball structure shrinks, resulting in small cracks on the surface of the europol — a line called “truck cracks”. Once the tortoise cracks cannot be repaired. Therefore, the maintenance of the europo is special: it cannot be placed in a dry environment, and it has been suggested that europe should be regularly "reduced" in clean water (controversially, some experts believe that bubble water is accelerating deterioration)。

Cold knowledge 5: kazayu is not named by birth
Many people think that "hakujia" is the jade of xinjiang and the field -- in ancient times, but not in modern times. According to the national standard gb/t 16552: kazayu is a jade stone, the main component of which is tremolite, regardless of origin. In other words, xinjiang's tremolite is called kazayu, and qinghai, russia, and korea's tremolite is legally called kazayu. The certificate only says "yazawa" and no place of origin. That's why it's the same "takuta" certificate, 10 times the price -- the place of production is the price, but the certificate doesn't tell you。
Cold knowledge 6: purple crystal colours come from natural radiation
Purple of the crystal is not "natural" but the radioactive elements in the earth's crust (e. G. Potassium-40) radiationed the iron elements of the crystal for millions of years, resulting in price changes in iron ion to produce purple. And even more amazing: heat the purple crystal up to 300-400°c, purple fades into yellow -- yellow crystal. A lot of cheap yellow crystals on the market are made of purple crystals. Heated to higher temperatures, it could turn green -- that's one of the sources of green crystal。

Cold knowledge 7: dove red is not really like dove blood
"dove red" is the best-quality commercial term for rubies, but it's not really like blood. The dove's red red is a "pure, saturated, slightly blue red" line termed "red in flames" instead of "black blood". The term is derived from the local saying in burma that the red is called dove blood only when it's a dove-eye iris. The dove's red ruby is actually closer in colour to "the red with a twilight" and very rich but not dark. International certificates such as grs (swiss gems institute) have strict standards for dove blood, and not all red rubies can be called dove blood。
Cold knowledge 8: cat-eye effect is not special material, it's sort of a package
Cat eyestone sounds like a special gem, and in fact the cat eye effect is an optical phenomenon — when there are a large number of parallel needles or tube-shaped packages inside the gems, a bright light belt appears in the light, like a cat's eye. Many precious stones produce cat-eye effects: golden eye, beige eye, moonlight eye, sea sapphire eye. Only the golden emerald cat eye can be called "cat eyestone" (others must be prefixed, such as "cat cat eye". The value of the cat's eye effect depends on the sharpness of the light belt and the flexibility of movement — the light belt shines more and more and more。
Reread the scriptures: fight the legends and fight the sand today
The world of jewels is much better than the lights in the counter. There are hundreds of millions of years of geological evolution behind each stone, and you know this, not just stone, but the history of the entire planet。
