Ruby, the birthstone of July, is also known as the king of precious gemstones. Symbolizing love, passion, and success, this vivid red gem had its name derived from the Latin word ruber, which means red. In addition to being the July birthstone, ruby is traditionally given for the 15th and 40th wedding anniversaries.
Rubies come in various tones of red, with the most valuable of rubies holding a deep red colour that resembles life force blood, or pigeon’s blood, hence why the more expensive gemstones are also known as pigeon blood rubies. Some rubies are more discolored than others so in order to fix this, they are often heat treated to remove discolouration to achieve a purer red colour. Due to it being the second hardest stone compared to diamond, the gems can be treated this way.
However, some rubies may also be subjected to lattice diffusion treatment and dyeing. In lower-quality gemstone, surface-reaching fractures and cavities may be filled with a glass to decrease their visibility so the gem appears more transparent. Some of these treatments may make the ruby more vulnerable to damage during normal wear and care.
In most cases, the July birthstone can be safely cleaned with warm soapy water and a soft brush. Ultrasonic and steam cleaners are usually safe for untreated, heat-treated and lattice diffusion–treated stones. Glass-filled or dyed stones should only be cleaned with a damp cloth. So be sure to know the quality of the ruby first before having it undergo a cleaning process. (Source: GIA)
