What are gold pearls used for?

Pearls are formed by two ways: natural formation of pearl mussels and artificial intervention.

A pearl is formed by an external foreign body entering the pearl mussel and touching its mantle, allowing the nacre secreted by the mantle to wrap layer by layer. It is mostly round and has tiny pores on the surface, and a multi-colored luster can be seen when observed. If you bite it with your teeth, it won't make a crisp sound and it won't leave a tooth mark.

When placed in the sun, it will be translucent and textured.

Features of pearls:

The appearance and characteristics of pearls are mostly spherical, different sizes, with a unique silver-gray-white brilliance, hard texture, layered sections, odorless, slightly salty.

In particular, it is better to have large particles, round shapes, pearlescent shining, smooth and delicate, and layered layers on the surface. Pearls are so beloved for their smoothness, roundness, brilliance, and brilliance that they have always been compared to gemstones.

The pearls in bubble tea are made of sweet potato powder, that is, starch dumplings, which are then soaked in syrup after being made into flour balls, which is to ensure that the flour balls can still maintain their sweetness in the sweet milk tea. Generally, the diameter of the round is about 7mm or more, and if it is too small, it is easy to become "full of pearls" when using a tea straw with a large caliber, and it is not convenient to taste the bite of the mellow aroma.

Introduction to bubble tea.

Bubble tea is now a very popular casual drink, especially among young people, this drink is handed down from Taiwan, China, and after adding the flour balls to milk tea, it becomes bubble tea. Bubble tea is one of Taiwan's "bubble tea" culture, and although it is only added to tapioca flour balls, it has become one of the most representative drinks and snacks in Taiwan.

Bubble tea generally uses larger granules, and the diameter after cooking is about 7 mm or more, otherwise the diameter is too small, it is easy to fill the mouth with pearls, and it is not convenient to swallow and chew. However, most bubble tea merchants still offer small pink pearls. Of course, there is also an "amber pearl", which is made with 100% brown sugar.

Pearls are hard, sleek products produced by mollusks, mainly oysters.

The color of pearls is related to the type of mother-of-pearl, and different mother-of-pearls secrete different colors of "natural pigments". For example, the mother oyster of the South Sea pearl is a golden-lipped pearl, and its edge is golden, so it can produce golden pearls; The black mother-of-pearl is a black lipped oyster, which is gray and black in color, and has a strong halo, so it can produce a lot of color changes.

How to care for pearls:

1. Avoid acidic and alkaline substances.

In order to avoid the pearl quickly turning yellow and tarnishing, it is the key to avoid touching acidic and alkaline substances, in daily life, do not wear makeup when wearing pearl jewelry, because when applying cosmetics, it is inevitable to touch pearl jewelry, which is easy to cause pearl jewelry to lose luster or turn yellow.

2. Avoid water.

Many people think that pearls are the product of mussels, and mussels live in water, and think that pearls should be able to soak in water, but this is actually wrong. There are two situations in which pearl jewelry can be soaked in water, first, water can enter the small holes of the beads, which is not only difficult to dry, but may also ferment inside, and the bead thread may also turn green. Second, if moisture penetrates into the pearl jewelry, it will cause the pearl layer to detach and damage the pearl.

3. Oil smoke. When wearing pearl jewelry, you can't touch the fumes, because there are tiny pores on the surface of the pearls, and if the fumes are inhaled into these small pores, the pearls will turn yellow, so the fumes are forbidden to touch.

4. Pay attention to safekeeping.

When wearing pearl jewelry, you must not put it together with other jewelry, because the surface skin of pearls is easy to be scratched, and when placed together with other jewelry, it is easy to rub, resulting in many scratches on the surface of pearls.

Pearls are not artificially made, but are produced in pearl oysters and mother-of-pearl mollusks. Pearls are calcium carbonate-containing mineral beads produced by the endocrine action of shellfish, which are composed of a large number of tiny aragonite crystals. There are many variety, different shapes, and colorful colors.

According to geological and archaeological research, pearls were already on the earth 200 million years ago.

In the international gem world, pearls are also listed as the lucky stone for the June birthday, and the 13th and 30th wedding anniversaries.

The quality is hard, difficult to break, and the section is layered. There is a cracking sound when it is burned with fire. There is no gas, and the taste is slightly salty.

The shape of the pearl is similar to that of natural pearls, but the surface luster is weak, and there are round sand grains or stone cassia fragments on the cross-section, and there is a real pearl layer on the surface. Only the pearl layer is used for medicine.

1. The smoothness of gold pearls is best to be smooth and unmarked. However, gold pearls generally have more or less cracks, scratches, unevenness, white spots or other imperfections, which can affect their value.

2. The shape of the gold pearl is as round as possible, that is, the "rolling bead" mentioned in the ancient book is the best. In addition to round, special-shaped or symmetrical shapes in good condition are also expensive.

3. The luster of gold pearls, the luster is the so-called "pearl" treasure, and the luster of the pearls is very important. The luster of a good gold pearl is that it radiates from the inside, and the light is strong and dazzling, uniform and distinct.

Pearls are products of mollusks, mainly oysters, and are hard and rounded. It is generally used in the jewelry and treasure industry. These animal-specific epithelial cells secrete calcium carbonate, mainly aragonite and calcite held together by chitosclecin. This blend is known as nacre.

Origin of Pearls:

In the case of injuries to the coat and carapace, the pearl will be secreted to the wound as a wound suture. Artificial pearls, on the other hand, are infused with nacre nuclei surrounded by a layer of foreign epithelium. The pearls secreted by these animals form from a few months to a few years.

The formation of large particles of pearls is likely to be fatal for the animal. In addition to pearl clams, there are other methods of producing pearls using other mollusc species with a nacre layer in their shells, such as some gastropod species such as abalone and snails.
