.Ruby Rods

  Ruby is another name of Red Sapphire,The crystal is doped with about 0.05% (weight ratio) of Cr2O3. The Cr3+ density is approximately 1.58×1019/cm3. Cr3+ is uniformly distributed in the crystal instead of the Al3+ position, optically belonging to a negative uniaxial crystal.

  The size of Ruby is limited by it's grow method, for now the maximum size Ruby rod we can supply is around D50 x 50mm.

  Typically, ruby is used as a mechanical bearing or as a tiny mechanical part such as a wire hole, mainly because it has a surface hardness second only to diamond, making it a wear-resistant, reliable mechanical component. Rubies are used instead of white because the red color of rubies makes these tiny parts easier to find, and to some extent, rubies can make devices look more high-end, a typical example of which is the ruby bearings used in mechanical watches. 

   Ruby rods can be roughly divided into two types according to their uses, one is mechanical use, that is, used as bearings or plungers, and the other is used as a gemstone laser. These two different uses of rubies determine the price gap between them, and if it is a mechanical grade ruby rod, the price will be much lower than that of laser grade rubies. Therefore, please inform us of your specific use when inquiring, if you do not disclose the use, we will generally quote you according to mechanical grade rubies.
