The difference between natural and non-natural red sapphires

Because natural gemstones are rare and expensive, it is difficult to meet the needs of market consumption, especially some natural high-quality, colorful, large-scale rubies, sapphires, etc. are more difficult to see in the market, and the high price is fascinating. Today, some physicochemical properties are basically similar to natural gemstones, and the price is cheap and good. The artificial gemstones with the main purpose of decoration are put on the market, which is undoubtedly a supplement to the natural gemstone resources. At the same time, due to the disparity in value, it also brings to the consumer market of natural gemstones. It is impossible to make up for the great panic. For business operators, even if an artificial gemstone is inadvertently sold as a natural gemstone, it will damage its reputation, so it is very important to accurately identify these artificial gemstones during the gem trade transaction.

Natural gemstones are single crystals (which can contain double crystals) produced by nature, beautiful, durable, rare, and can be processed into decorative minerals.

2. What is an artificial gem?

A crystalline or amorphous body that is artificially manufactured and has no known counterpart in nature is called an artificial gemstone.

3. A crystalline or amorphous body which is wholly or partially manufactured by hand and has a known counterpart in nature, the physical properties, chemical composition and crystal structure of which are substantially the same as the corresponding natural gemstone.

Natural red sapphire, artificial red sapphire, synthetic red sapphire features:

1. Natural:

1 Ruby: The color is bright and bright but very uneven, and there are different shades of the ribbon. The inclusions are arranged in a certain direction. The fibrous rutile and the fingerprint inclusion are the most common inclusions, and the crack faces are jagged or along. The texture on the crystal face develops flat.

2 sapphire: the color is uneven, visible in parallel with different shades of light and straight growth lines, in addition to the crepe, the inclusions also have a large number of gas-liquid inclusions, they are in the same plane, forming a unique Feathery, lotus-like, diffuse inclusions.

2 sapphire: crystal color is more uniform, less internal defects, less inclusions, common teardrop-like, beaded circular bubbles.

3. Synthesis:

1 Ruby: Fluorescence is stronger than natural ruby, bright red under ultraviolet light; after processing, dichroism can be seen on the surface of synthetic ruby ​​facet, while natural ruby ​​only shows dichroism in the waist direction.

2 Sapphire: Same as ruby.
