July Birthstone

 

Ruby is the birthstone of July.  

The name comes from the Latin word rubeus, which means red. Rubies have been celebrated in the bible and ancient Sanskrit writings as the most precious stone.  Rubies in Sanskrit were called ratnaraj, which means "King of the precious gems." According to Hindu lore, the vibrant glowing red color of ruby is caused by eternal flames burning within them that cannot be extinguished.  It was claimed that the owner of a ruby was guaranteed a peaceful and harmonious life, as well as brought luck and good fortune.  Rubies are also legendary symbols of everlasting love.  Rubies are very hard and resilient gems, second only to diamonds.

The most valuable rubies are sourced from Burma, but all high quality rubies have been depleted in this area.  The brightest and most valuable red color is called "pigeon blood".  Today many rubies are sourced from Madagascar but their color and brilliance does not come close to Burmese rubies and are worth much less.

A 32.08 carat ruby ring was sold for $6,742,440 at Lily Safra's jewelry auction in 2012.  The auctioned price was the highest ever price for a ruby sold at auction.

Rubies come from the family of corundum.  This is the same family as sapphire.  The intensity and brightness of the color is what differentiates pink sapphires from rubies.  Some dark pink or red sapphires are called rubies but they are not true rubies according to GIA (Gemological Institute of America) standards.  When you buy rubies you must be careful that it is not a sapphire which are less valuable.

Today a lot of rubies have many different treatments.  The only acceptable treatment for fine jewelry is heat treatment.  All other treatments are highly disapproved of and significantly reduce the value of the stone.  Such treatments, for instance include inserting glass pieces to fill up small gaps left after the cut.  There are also many synthetics on today's market.  Falsifications can only be identified by a professional.  This is another reason why it is crucial to buy rubies from an expert.
