Look at the color. This color can be used to identify emeralds. The color of emerald is a special and crystal emerald, and its green beauty is incomparable to any green gem, while the fake emerald gives people a dim and gray feeling. Weigh.
If the color of water is green from any angle, it means it is really emerald. If not, it is synthetic. Emerald is characterized by transparent emerald, and its color is a special and crystal emerald, and its green beauty is incomparable to any green gem.
The main difference between them is that most synthetic emeralds are usually bright and uniform in color. Different from natural emeralds, they have higher clarity, strong red fluorescence and bright red color under Charles filter.
Looking at the appearance of natural emeralds, most of them will have flaws and cracks, similar to rubies. Most of their defects are "cotton wool"-like, and sometimes some impurities such as black mineral inclusions can be seen. Synthetic products are mostly clean, or there are a few bubbles.
The identification methods of emeralds include color, transparency, cutting method, refractive index, heavy liquid method and Chelsea filtration method.
How can emeralds distinguish between true and false?
1. Professional jewelry appraisers need to carry out basic gemological tests on emeralds to identify the authenticity of emeralds. Basic gemological detection includes: refractive index, absorption spectrum, ultraviolet fluorescence, magnifying observation, etc.
2. Look at the contents. The most prominent feature of natural emeralds is internal inclusions. Most natural emeralds have defects and inclusions mixed with solid, liquid and gas. Synthetic emeralds are often clean, and the inclusions in them are mostly gas or gas-liquid mixture, often in the form of smoke clouds or plumes.
3, put the gem in red charcoal, charcoal incense, fire immediately put out, this is the real thing. The colors are mostly transparent, bright emerald, yellow-green and so on. The appearance is soft and fluffy, and the inclusions in the polarizer are bright. It rotates 360 degrees, and there are four kinds of light and shade changes. It is not an isotropic body, but an object.
What is the difference between emeralds and emeralds?
1. Emerald is a polycrystalline aggregate jade, and emerald is a single crystal gem. Jade, also known as jadeite, jadeite, jadeite and Burmese jade, is a kind of jade.
2. Emerald is a kind of jadeite mineral, which consists of many different very fine minerals. Therefore, the chemical composition and physical properties of emeralds and jadeites are completely different, which is one of the differences between emeralds and jadeites.
3. Different categories: they are different in composition. Emerald is a gem, which is a single large mineral particle and presents the glass luster of a gem. Emerald is composed of many small minerals, from transparent to opaque, showing the luster of wax to glass, and the color is richer.
Identification of Emerald How to Identify Emerald Jade
1, look at the shape. Most natural emeralds have flaws and cracks, similar to rubies. Defects are mostly "cotton wool"-like, and sometimes some impurities such as black mineral inclusions can be seen. Synthetic products are mostly clean, or there are a few bubbles. Look at the color.
2. Distinguish emeralds from jadeites by looking at varieties, colors, minerals and hardness.
3. Different colors. Emerald is a color with a little blue hue, even, delicate, pure, saturated, rich and deep. Different hardness. The hardness of jadeite is undoubtedly greater than that of jadeite. The hardness of natural emeralds is Mohs 5~8, while that of jadeite is Mohs 5~7.
What is the difference between emeralds and emeralds?
1. Emerald is a polycrystalline aggregate jade, and emerald is a single crystal gem. Jade, also known as jadeite, jadeite, jadeite and Burmese jade, is a kind of jade.
2. Emeralds of different colors are very rare gems. Its color is even and crystal clear. Visually, it contains blue emerald. Compared with jadeite, emerald is more uniform, rich, soft and transparent.
3. Different texture: Emerald is a single crystal gem, unlike jadeite, which is composed of tiny minerals, showing the glass luster of gemstones. Emerald is a polycrystalline aggregate jade with jadeite mineral as the main component, and its color is uniform.
Emerald and emerald are two completely different substances according to their chemical and physical properties. Emerald is a rock and emerald is a mineral; Emerald is jadeite, translucent, and emerald has glass luster; In addition, there are differences between colors and impurities.
5, texture. Jade and jadeite are quite different in texture. Emerald is a kind of single crystal gem with Mohs hardness of about 5~8. Jadeite belongs to polycrystalline jade, which is an aggregate mainly composed of jadeite minerals, and its Mohs hardness is between 5 and 5. Color.
