  Synthesis principle

  The real alumina (Al2O3) natural powder and colorant are dissolved in a hydrogen-air flame at about 2000°C, and then cooled and solidified to form a single crystal ruby.sapphire red color，

  Surface area characteristics

  1. Initial crystal form: The original crystal form of ruby synthesized by flame smelting method is pear-shaped crystal, which can also be damaged with pear-shaped crystal and sold as ordinary ruby wool in the production area or mining area.

  2. Chroma: It is a kind of synthetic ruby that uses flame smelting method to find the phase, and the color is purer and more pleasing to the eye than organic rubies. With the development of the activity process, the chromaticity of the ruby synthesized by the flame smelting strategy is becoming more and more abundant, and the color can only be used as a part of the auxiliary detection attributes.

  3. Fissure-like surface area texture: Sometimes the dressing procedure of artificial ruby is not paid enough attention, in fact, it is easier to create a fissure-like area structure.
