You’d be hard pressed to find someone who doesn’t love rubies, with their beauty and incredible color. Their durability and value is legendary. (Use them for shoes, however, and they can get a house dropped on you.) For those born in July, rubies are a special birthday gift they didn’t even have to ask for.
In their finest quality, rubies are a brilliant red almost unmatched by any other gemstone. (The Black Prince’s Ruby, found in the British Imperial State Crown, is really a huge red spinel. Had everyone fooled for a long time.) Yet there are lots of rubies that are not the finest quality. What makes a good ruby?
First, that brilliant red color. Rubies are red. A “light” ruby—meaning leaning toward pink or purple rather than red—may be called a ruby, but it’s considered in gemological circles to be more accurately described as a pink or purple sapphire.
