Red Spinel
 
Prior to the late 18th century all red gemstones were called rubies as stones were classified solely by color. It wasn’t until 1783 that red spinels were chemically differentiated from rubies and a specific gemological hierarchy was established.  Red spinel ranges in color from orangy red to purplish red, with a pure medium to dark tone red considered the very finest. 
 
One of the most well-known red spinels, the Black Prince’s Ruby, is a large, irregular cabochon weighing 170 carats. This iconic stone sits above the Cullinan II Diamond on the British Imperial State Crown. It has been cherished by England’s rulers since it was first presented in 1367 to its namesake Edward of Woodstock, the “Black Prince.” 
 
In the last several decades the demand for fine red spinels of good size has far exceeded the available supply, making them highly desirable to jewelers and collectors alike. And unlike rubies, which are typically treated to improve their color, spinels have no need for such enhancement, making them a true connoisseur’s gem.
