What are synthetic gemstones and the difference between synthetic and lab grown gemstones

Synthetic gemstones are made in a laboratory or processing plant, not from rocks. Their chemical composition and crystal structure are similar to those of natural gemstones, so their optical and physical properties are also very similar. However, it can be identified by its inclusions.

Many gemstones have been synthesized in laboratories, but only a few are produced commercially and are generally used in industry and scientific research.

Shape and color.

Depending on how they are formed, synthetic gemstones may be somewhat different in shape and color from their natural counterparts, which can help to identify them.

For example, corundum lines made by flame melting are curved because the ingredients are not sufficiently agitated; Some synthetic gemstones have uneven color distribution; Flame fused spinel.

It can be used to imitate ruby, sapphire, aquamarine, blue zircon, tourmaline, noble peridot and chrysoberyl, etc.

Unique Inclusions.

Synthetic gemstones have different inclusions than natural gemstones, and the best way to identify them is to look at them with a lens or microscope. Synthetic inclusions are some kind of processing or some kind of synthetic gemstones.

unique. For example, the outline of the bubbles in the Verney ruby is very clear;

Emeralds, which are fused with fluxes, form a unique "veil" and "feather" pattern.

Natural gemstones. 1) Natural gemstones.

Naturally occurring monocrystalline minerals.

2) Natural jade.

Naturally occurring polycrystalline rocks. 、

3) Natural organic gemstones.

Materials formed in relation to animals and plants and meet the requirements of the process, such as pearls, coral, tortoise shells, amber, coal essence, ivory, etc.

Improve gems.

1) Optimize gems.

It refers to the improvement of the appearance of gems and jade, such as luster, color, transparency, etc., without damaging and damaging the various physical properties of gemstones and jade, so as to make gems and jades beautiful, such as the stewed wax of jadeite and the heat treatment of red sapphire.

2) Dealing with gems and jade.

In order to make the appearance of gemstones more dazzling, often filling, coloring, coating and other treatment of some poor quality gems and jades, these effects often have certain damage and damage to the structure, solidity and other physical properties of gemstones, and its appearance will change to varying degrees soon after treatment, such as bleaching and filling treatment of jadeite and diffusion coloring treatment of red sapphire.

3) Flattening the gemstones.

Assembling gemstones generally refers to two or more parts of the same kind of gemstone or heterogeneous materials bonded and pressed together into jewelry, the most common on the market is opal two-layer stone and three-layer stone, some of the gems and jades pressed by fragments such as turma, amber, etc. also belong to this category.

3 Artificial gemstones.

1) Synthetic gemstones.

Synthetic gemstones refer to artificially produced materials that are basically the same as the chemical composition, physical properties and structural structure of natural gems and jade, such as synthetic corundum, synthetic crystal, etc., also known as synthetic materials.

Artificial gemstones. Artificial gemstones refer to man-made materials that are produced by nature and have no counterparts that are similar in appearance to gemstones, such as cubic zirconia, silicon carbide, yttrium almandine, etc.

Imitation gemstones. Controlled gemstones refer to man-made materials or some natural gemstones that are basically similar in appearance to a certain natural gemstone, but completely different from the chemical composition, physical properties and structural structure of this natural gemstone, such as cubic zirconia, silicon carbide and natural zircon, which are similar to diamonds in appearance, but the chemical composition, physical properties and crystal structure are completely different from diamonds, and are often used to imitate diamonds.

Material and **.

1. Material. The material of synthetic gemstones is relatively coarse, and the material of lab-grown gemstones is relatively smooth.

2、**。Synthetic gemstones are in the thousands, and lab-grown gemstones are in the tens of thousands.

1. Different properties: artificial gemstones are completely or partially artificially produced or manufactured, and are used as materials for jewelry and ornaments. Synthetic gemstones, on the other hand, are crystalline or amorphous bodies that are wholly or partially manufactured and have known counterparts in nature.

2. Different compositions: synthetic gemstones are artificial gemstones generated by artificial crystallization or recrystallization methods according to the chemical composition of some natural gemstones, simulating the physical and chemical conditions when they are formed in nature. Artificial gemstones are not.

3. The naming method is different: in addition to the heat-treated gemstones, the gems optimized by other methods must be added with the word optimization, otherwise it will be regarded as deception. Synthetic gemstones are not.

1. Synthetic gemstones: they are manufactured in laboratories or processing plants, not from rocks;

2. The chemical composition and crystal structure are almost the same as those of natural gemstones, so their optical and physical properties are also very similar;

3. Many gemstones have been synthesized in laboratories, but only a few are produced commercially and are generally used in industry and scientific research;

4. Due to the different ways of formation, synthetic gemstones may be somewhat different from natural genuine products in shape and color, which is helpful for identification;

5. The corundum lines made by flame melting method are bent, because the ingredients are not fully stirred;

6. The color distribution of some synthetic gemstones is uneven;

7. Flame liquid lead disturbance fusion spinel can be used to imitate ruby, sapphire, aquamarine, blue zircon, tourmaline, noble olivine and chrysoberyl and other irritation;

8. The inclusions of synthetic gemstones are different from those of natural gemstones, and the best way to distinguish them is to use an inch mirror or microscope to inspect them;

9. Synthetic inclusions are unique to a certain processing process or a certain synthetic gemstone.

Summary. Hello, dear, very happy for your question, what are the advantages of synthetic gemstones over natural gemstones, help you find out that the synthetic output is large and stable, the gemstone particles are large, the internal flaws are few, the color is bright, and it is much cheaper than the natural one, I hope mine can help you, I wish you good health and a happy mood!

Hello, dear, very happy for your question, what are the advantages of synthetic gemstones over natural gemstones, help you find out that the synthetic output is large and stable, the gemstone particles are large, the internal flaws are few, the color is bright, and it is much cheaper than the natural one, I hope mine can help you, I wish you good health and a happy mood!

Pro, the synthetic yield is large and stable, the gemstone particles are large, the internal blemishes are few, the color is bright, and it is also much cheaper than the natural one. Natural gemstones are produced by nature, with beauty, durability and scarcity, and can be processed into mineral single crystals (can contain double crystals) for jewelry, such as natural diamonds, ruby sapphires, emeralds, etc. Synthetic gemstones, crystalline, amorphous or II-like mixtures wholly or partly manufactured and with known counterparts in nature, have essentially the same physical properties, chemical composition and crystal structure as their natural jewelry counterparts.

However, they are formed in different environments, and the formation cycle is also very different.
