How to identify red corals and where to identify red corals

I don't know much about it in a nutshell:

1. The coral ornaments imitated by sea willow and sea bamboo have obvious longitudinal textures and single colors, giving people an unvivid feeling and no unique pore characteristics of coral jade.

2 Filler coral dyeing is made of shallow sea dendritic reef coral with loose texture, which is filled and dyed by glue injection, and its surface is smooth, but it is actually rough and brittle, and the color is easy to fade.

3 Synthetic coral dyeing is a variety of coral shapes made by grinding various shellfish or reef-building corals into powder and molding, with no natural texture, and almost every coral is the same.

4 All kinds of jade imitation coral are dyed with dolomite or calcite, and the color is uniform but easy to fade and have no luster.

Corals are divided into two categories:

One is our common shallow reef-building coral, which has a loose texture and cannot be processed into beautiful jewelry;

The other type is gem-quality corals with dense texture and rich color.

Gem-quality corals are very selective in their living conditions: 200-2000 meters deep in the deep sea; The water temperature is around 13 degrees; The water is slower and the water is clearer.

Such a living environment is destined to slow growth, scarce yield, and difficult mining, which is also the reason why red coral is high in the market.

Due to historical reasons, the mining, processing and sales of red coral all over the world are basically completed by Taiwan, so we are accustomed to calling red coral Taiwan red coral.

Red Coral】 Hardness:

Specific gravity: varieties: deep-water, momo, sardine, acre, of which acre is the most valuable.

Maintenance of red coral].

In addition to the general maintenance methods of red coral like other gemstones, due to its special physical and chemical properties, it is destined to be complicated to wear and maintain.

Red coral jewelry should not be worn in the following situations:

strenuous physical activity;

Bathe; Cook;

Swim; Sweating, etc.

If it is black and dirty, please take it to a professional red coral company and have it re-polished by a professional.

Hope this information is helpful to you hehe.

First of all, what varieties do you have to distinguish, aca, sardine, mo, deep water? With the same quality, ** decreases in turn, and then depends on the color, weight or diameter, the redder the color, the larger the diameter, the more expensive. From a few hundred dollars to several thousand dollars.

If the diameter is more than 10mm, don't consider Aka, a bead will cost thousands, and the most crimson will cost tens of thousands. But many merchants sell dyed coral, generally dyed with white coral, known as "natural coral", this is true, white coral is also natural, but it is not red coral after all, the color is also dyed, and the real ** string is only a few dozen yuan. Appraisal reports are also of little use.

The certificate does not tell you what breed it is, it just indicates whether it is natural or not. Appraisal agencies are also not fully credible, and some also give certificates for white coral dyeing. Because it is indeed "natural" as well.

Summary. Dear, hello, I'm sorry, I've been waiting for a long time, the place to identify red coral: Peking University Gem Identification Center:

It is an academic authoritative jewelry testing and appraisal institution with an independent legal person established on the basis of the gem appraisal laboratory of the former Department of Geology of Peking University. Backed by Peking University, the country's highest university, a century-old famous university, it has extremely strong technical strength. It has a high reputation and social and international credibility!

How to identify the authenticity of red coral?

Dear, hello, I'm sorry, I've been waiting for a long time, the place to identify red coral: Peking University Gem Identification Center: It is an academic authoritative jewelry testing and identification institution with an independent legal person established on the basis of the gem identification room of the former Department of Geology of Peking University.

Backed by Peking University, the country's highest university, a century-old famous university, it has extremely strong technical strength. It has a high reputation and social and international credibility!

It's too far. Identifying the authenticity of red coral: 1

Look at the texture: red corals have longitudinal stripes parallel to the direction of coral growth, and the arrangement is relatively tight. The cross-section of the red coral has rings like tree rings, and these two textures should be noted when identifying them with the naked eye.

2.Look at the color: The color of red coral is a vivid and vivid red, whether it is light or dark, it is alive, not s i, not depressed!

The red coral has a bright waxy luster, while the dyed red coral has no luster and the color is also depressed.

3 .Listen to the sound: Real corals look delicate but have a crisp and hard sound when they collide with each other.

Generally, plastic or other imitation coral does not exhibit this hard and crisp sound. This sound is especially evident on the branchy corals. 4.

Weight: Coral has a good sense of weight, generally placed in the palm of the hand will give people a sense of heaviness that does not match its delicate feeling, this weight is also one of the bases for distinguishing red coral from some inferior imitations.

Red corals can be wiped with alcohol, real red corals are stupid after contact with alcohol, there is no change, and fake ones will fade. You can also observe the color of the surface, the color of the true red coral is naturally bright, and the color of the false red coral is a little dull. You can also observe the surface lines, there are growth lines on the surface of true red coral, and there is no trace of lines on the surface of false red coral.

1. Alcohol identification red coral can be wiped with alcohol, wipe the red coral with cotton swabs and cotton balls dipped in alcohol, or directly wipe the red coral with alcohol wipes, the real red coral has no change, and the fake red coral will fade.

2. Color identificationRed coral can observe the surface color, and the color of the surface of the real red coral is naturally bright, showing wax or oil luster. The color of the surface of the fake red coral is a little dull, and there is only a touch of light on the surface, which looks a little dull.

3. Texture identification of red coral can observe the surface texture, and there are growth lines on the surface of real red coral, which is the trace of polyp growth. The surface of the fake red coral is very smooth, without a trace of lines, and some are smooth and translucent.

Summary. After all, the natural special growth mode of red coral leads to a very special texture of red coral, and all fake red corals cannot be the same as the lines of real natural red corals. For example, sea bamboo dyeing and red coral, or red coral colored with animal bones, the lines are different from natural red coral, after cutting, the cross-sectional lines are radial and very obvious, but the lines of natural red coral are relatively inconspicuous, and are distributed in the form of flowing water or swirls.

The most effective and intuitive way to identify red coral, that is, to look at the lines, after all, the natural special growth mode of red coral, resulting in red coral has a very special pattern, all fake red coral, the texture can not be the same as the real natural rotten next to the red coral. For example, sea bamboo dyeing and red coral, or red coral colored with animal bones, the lines are different from natural red coral, after cutting, the cross-sectional lines are radial, and very obvious, but the lines of natural red coral, Hunger Xun is less obvious, and is water-like or vortex-like distribution.

I'm sorry I don't understand, but can you elaborate on that?

Besides, the only way to do it is to do the appraisal!

Real red coral, one is according to the certificate, if there is a test certificate issued by a formal testing agency, the ** and the real thing on the certificate is one-to-one, that is to say, each object has a unique certificate, if you weigh this, if it meets, it can be basically determined that it is true.

The second is to look at the real thing, the natural red coral is observed with a magnifying glass, and its practical eyes can also be seen with the naked eye, with red and white stripes, which is a more typical feature.

When it comes to this bracelet of yours, the red color is very bright. For natural red coral, this color is very good, ** not low, such bracelets on the market are generally Italian sardine red coral.
