Rubies

Passion, love and power.  With its intense colors and qualities, rubies have inspired mysticism in man since their discovery.  Ruby, the birthstone of July, is said to assure the owner a life lived in peace and concord with all men; neither his land nor his rank will be taken from him, and his house and garden would be saved from damage by tepests. Christians, Jews, Hindu all believed rubies to be the most precious and powerful of the gemstones, calling it the King of Precious Stones.  Other cultures believed rubies to have healing properties.

 

The ruby is a member of the Corundum family and relies on aluminum and oxygen to create its crystal and chromium and oxygen to give its vibrant red coloring.  Rubies come in a range of hues from purplish red to orangish red.   The color is magnified by the nature of a ruby’s crystal.  The natural fine particles help to scatter light throughout the stone’s facets. Ruby is a hard mineral, rating a 9 on Mohs scale, but must be handled with care as it can be very brittle.  Technology has brought with it treatments of rubies using heat to intensify the color.  Heat-treatment reduces value in the stone.

 

Rubies are mined all over the world, but mainly in Southeast Asia and Africa. The origin of a ruby affects its characteristics and value.  Burma rubies which are mined in the Myanmar region and Thai rubies are among the most desirable.

Sapphires

Loyalty, sincerity and faithfulness. Sapphire, the birthstone of September, is the gemstone of the soul and autumn; and in ancient times was said to protect the wearer from envy and attract divine favor.  Bishops have worn sapphires in their ecclesiastical rings since the 12th century and is said to be the stone used for Moses’ tablets.

 

Interestingly, the sapphire come from the same mineral family of Corundum as the ruby. But unlike the ruby’s one intense red color, sapphires come in colors that span the spectrum.  Fine blue sapphires are among the most ideal and desired.  But sapphires are also found in pink, yellow, green and violet. The combination of iron and titanium is credited for the color of sapphires although there is evidence of other causes.   Sapphires are found in India, Myanmar (Burma),  Ceylon, Thailand, Vietnam, Australia, Brazil and Africa.  The most desirable origins are Burma, Ceylon and Kashmir as they are known to produce the most beautiful sapphires each with unique attributes.

 

Sapphire rates a 9 on the Mohs scale of hardness and like all gemstones must be handled with care in order to prevent cracking, chipping and shattering.  Technology has brought with it treatments of sapphires using heat to intensify the color.  Heat-treatment reduces value in the stone.
