Prices of ruby jewelry rings are mainly determined by color. The brightest and most valuable rubies – called pigeon-blood red – command a huge premium. Similar to diamonds, a clear ruby will command a very high price, but a ruby without any needle-like inclusions may indicate that it has been treated. Almost all rubies are treated in some form, with heat treatment being the most common practice.
Rubies are purported to have very powerful healing properties. Ruby jewelry rings are first and foremost supportive of the heart. They are said to balance love and spiritual endeavours, to boost self-esteem, and to prevent miscarriages.
Tales of transport and trading of the spectacular red gemstones used in ruby jewelry rings pop up regularly in historical records. One such mention was trading of rubies being carried westwards from China along the North Silk Road, about 2,200 years ago.
