The chemical composition of Ruby Gemstone is Aluminium Oxide (Al2 O3). [17] In nature, there are rarely pure hues, so when speaking of the hue of a gemstone, we speak of primary and secondary and sometimes tertiary hues. Synthetic gems have the same chemical, optical, and physical properties of their natural counterparts, but are a more cost-effective alternative to a natural gem. After cooling the color of the paste is fully transparent and dramatically improves the overall transparency of the ruby. Filling the fractures inside the ruby with lead glass (or a similar material) dramatically improves the transparency of the stone, making previously unsuitable rubies fit for applications in jewelry.
