1, black diamond

The mysterious black diamond may be an alien visitor?

Black diamond, also known as black diamond, has a black porous structure and its hardness is equivalent to that of other diamonds. But strangely, only Central African countries and Brazil can find black diamonds, and a small part of them are found in South African countries, not in kimberlite where diamonds are usually found.

The origin of black diamonds is not clear. On February 30th, 2006, in Astrophysics Newsletter, 65438, some experts pointed out that there might be black diamonds in the universe long before the birth of the earth. Scientists have found a lot of hydrogen in black diamonds, which shows that it comes from outer space rich in hydrogen.

2. Precious black diamonds

Since 1900, about 600 tons of ordinary diamonds have been mined, polished and traded and regarded as treasures. But in all the diamond mines, no black diamonds were found. Black diamonds are particularly precious because they are rare.

Many people think that the clarity of black diamonds is very low, but this is not true. The clarity of black diamonds is not low, but black diamonds usually have low clarity grades. We must understand that the grading system of colorless diamonds is not suitable for black diamonds.

3. Black pointy crystal

Black spinel has sub-diamond luster and hardness of 8, which is mainly produced in Mexico.

Spinel is composed of magnesia-alumina oxide, which contains different chromogenic elements and has rich and varied colors. When the iron content reaches a certain level, spinel will appear black.

Black spinel is a kind of diamond with sub-diamond luster, which is not as shiny as black diamond, and seems to reveal a thick dark atmosphere in mystery. If you are a staunch supporter of Gothic style, then black spinel will be a good choice.

Its high temperature resistance and colorfastness make black spinel an easy-to-maintain gem.

4, black agate

Black agate has glass luster and hardness of 6.5-7. High-quality black agate is mainly produced in Brazil and South America.

Pure black agate is rare in nature, because agate contains a lot of organic matter, and uneven organic matter content will show bands of different shades. These bands can have different colors (red, blue, purple, green, black, white, etc. ). If it is black and white, it is called black agate; Those with red and white stripes are called silk-wrapped black agates.

Some people think agate is not a precious gem. In fact, there is a big difference between gem-grade agate and jewel-grade agate. Because agate contains uneven organic matter, there are few agates with pure and flawless color. Therefore, agate that can appear as a gem is one in a million.

Maintenance of black agate

I'm afraid of heat

Attention should be paid to avoid heat sources, such as sunlight and stoves, because black agate will expand when heated, and the increase of molecular volume will affect jade quality, and continuous contact with black agate at high temperature will also lead to black agate bursting.

Moisten me

In addition, black agate should maintain proper humidity, especially water-filled black agate contains natural moisture during its formation. If the surrounding environment is very dry now, it will cause the evaporation of natural water inside, thus losing artistic and economic value.

5. Black Pearl

At present, there are only two main natural producing areas of black pearls:

One is Tahiti in Polynesia, which produces 95% of the world's black pearls;

Followed by Penglin Island and Majushiki Island in Cook Islands, accounting for 4% of the total output.

These two areas live together in the south-central Pacific Ocean, so they are also called black pearls as black Nanyang pearls.

Fritillaria, which produces black pearls, is a kind of black butterfly shell that secretes black nacre. The beauty of black pearl lies in its natural black tone and various colorful colors, among which the most appreciated are malachite green, deep purple, navy and other rainbow colors. Its strong metallic luster will change with the rotation of the pearl, which is incomparable to other color-changing pearls.

There are also natural and cultured black pearls, and natural black pearls are more precious, because the growth process of black pearls is very difficult, and its formation is very strict with various external factors such as growth environment and temperature.

Even in the case of artificial breeding, there is only a small chance to breed black pearls, so the annual output of black pearls is estimated to be no more than 6.5438+0.5 million, and a large part of them will be sold through international auctions every year.

Before you buy black pearls, you should know.

1, look at the color

The true natural black pearl has different shades from light gray to black, and its beauty lies in its halo. Turn the black pearl slowly, and you can see the slight rainbow-like flash changing constantly. Natural black pearls are not pure black, but malachite green black, dark blue black, gray or black with bronze hue, with a slight rainbow-like flash.

Generally speaking, pearls with darker halo are more precious, so half of malachite green and black pearls will be more expensive than gray ones.

You can also tell whether the black pearl is true or not by observing the color. After dyeing, the color of black pearls is uniform, and the black color gathered in holes and cracks is dark, which belongs to color deposition.

Step 2 look at the smoothness

The so-called pearls are round and jade-like, which has a deep reason. High-quality black pearls should be full-grained, round, close to standard spherical, without scratches, flaws and traces.

The surface of high-quality black pearls should be very smooth, and there are almost no tiny concave and convex surfaces under the light. The appearance should be brilliant, which can reflect the changing and charming halo color to the light source.

Step 3 look at the size

Most of the natural black pearls are Pinctada maxima, which breeds large nuclear pearls. Generally, the particle size is rarely less than 9 mm, so those less than 8 mm are round black pearls, mostly irradiated products. Black pearls discolored by radioactive radiation are rich in halo spectrum and accompanied by strong metallic luster. The treated nacre of this pearl is inert to long-wave ultraviolet radiation.

4. Look at the luster

When rating pearls, the "glossiness" among them is considered to be equivalent to "floodlight". High-quality natural black pearls reflect light evenly and strongly, and the image is very clear. At the same time, each black pearl has a unique color and halo, and we can see the change of halo when we observe it. Every angle has color change, and the gloss is very strong, which belongs to the top grade.
