Types of Synthetic Corundum
8 Cushion Cut Ruby Corundum
Synthetic corundum is a remarkable achievement in human materials science, referring to crystals created in laboratories that possess identical composition (Al₂O₃ + Cr) and physical properties to natural rubies. With its exceptional hardness, stable physical and chemical characteristics, and vivid, enduring red color, it is both a favorite in the jewelry industry and a vital pillar for high-tech industries.
Rectangle Ruby Corundum
Beyond serving as a primary material for jewelry, its consistent optical properties and physical stability have led to widespread application in high-tech fields such as medical laser equipment, aerospace instrument windows, and high-precision mechanical wear-resistant components.
Round Green Corundum
Synthetic corundum is produced in laboratories or industrial settings through artificial intervention to synthesize corundum crystals. The primary component of corundum crystals is aluminum oxide, identical to natural corundum.
Pear Ruby Corundum
Its physical properties are exceptional: high hardness grants it remarkable durability, making it ideal for daily wear; stable chemical composition ensures resistance to acid and alkali corrosion; and outstanding optical characteristics yield a rich, pure red hue.

Features of Synthetic Corundum
Hardness
With a hardness of 9 on the Mohs scale, synthetic corundum is extremely resistant to scratches, second only to diamond.
Colour
The colour of synthetic corundum can vary depending on the elements added during its manufacture. For example, chromium produces red rubies, while iron and titanium produce blue sapphires.
Purity
The manufacturing process allows inclusions to be controlled, making the stones often clearer and purer than their natural counterparts.
Transparency
Synthetic corundum can be manufactured to achieve high levels of transparency, which is ideal for high quality jewellery.
