Very rare to find a completely natural ruby - almost all rubies have been treated in some way to improve the color or strength . Therefore, it is important to understand the different treatments , how they affect the ruby, and what to tell your jeweler if you need a treaty worked jewels.
The most common treatments applied to ruby jewelry is a heat treatment, surface diffusion , fracture filling, and filling the cavity.
heat treatment
The number one most common treatment for ruby is heat treatment . This involves heating the rock at very high temperatures ( in the neighborhood of 3,000 degrees Fahrenheit ) , infused with a deep red color , rich. A side effect of heating is small fractures are healed and filled with residual heat. These effects are permanent and can not be detected by an expert gemologist .
Heat treated rubies are color stable and powerful (if not more ) than natural stone , but if you need to have the work done in stone , it is important to tell the jeweler that has been treated .
surface diffusion
The application of a heat treatment at a ruby , in the presence of a coloring agent , to create a strongly colored surface layer on the surface of the stone. It is therefore extremely pale ruby , sapphire or clear.
On Ruby is nothing more than a red sapphire, and a clear sapphire treated in this way is considered a true (but not all-natural ) ruby . Surface diffusion is a stable and permanent treatment under normal conditions , but can be destroyed if the ruby is cut .
filling fractures
Sometimes the petroleum resin or color is used to fill small fractures in ruby . This also improves the color and clarity of the stone , but it results in stability and exceptional strength. Exposure to heat or chemicals can damage the loads that are commonly used.
Fill the cavity
This is a similar fracture filling process , and is very common. As with fracture filling , this will improve the color and clarity, but the exposure to heat and chemicals can destabilize rock slightly.
